Description

Escape the daily grind and immerse yourself in the natural world. Rich in imagery, sound, and information, BirdNote inspires you to notice the world around you.

Episode Date
Insects Are Essential
00:01:39

Insects sustain our ecosystems, as a food source and pollinators of 90% of all plants. But their numbers have dropped by half in the last 50 years, so it is now critical to help foster insects. One concrete way to help is to grow native plants that provide food and shelter for insects like caterpillars. Growing such plants directly benefits birds and helps insects keep the natural world ticking.

How the Woodcock’s Journeys Connect Us
00:01:45

In this show, Marcus Rosten shares his involvement in a study of the American Woodcock with the New York State Department of Environmental Conservation. The study revealed the surprising journeys of one of North America’s quirkiest birds. One woodcock caught near Buffalo flew nearly 400 miles south without stopping, en route to spend the winter in North Carolina. Migrations like the woodcocks’ help connect people all over the continent and highlight the importance of making sure these birds can find safe places to live throughout their range.

Lilli Holden on Birding with Students in Chicago
00:01:45

Lilli Holden is an emerging environmental leader in Chicago. She visits local schools and leads students outside to see birds. Lilli says the students’ enthusiasm while birding is contagious. But while visiting various neighborhoods in Chicago, she sees stark differences in access to nature, tied to the history of segregation and divestment in Black communities. She says that people’s needs for viable forms of public green space should receive more attention going forward.

Lauren Pharr on Being a Black Field Biologist
00:01:45

For her PhD, Lauren Pharr took on a challenge: studying Red-cockaded Woodpeckers, which make their nests high in pine trees. But as a Black woman working as a field biologist in the rural South, Lauren says she faces higher levels of risk than her white colleagues. Lauren co-founded an organization called Field Inclusive that raises awareness about how to promote the safety of people from marginalized backgrounds in the field.

The Freedom Song: Harriet Tubman’s Barred Owl Call
00:01:45

Harriet Tubman was a heroic abolitionist in the cause to end chattel slavery. She was also an excellent astronomer and naturalist — and an expert birder. She mastered the hoot of the Barred Owl, using it as a signal throughout the Underground Railroad to let freedom seekers know she had arrived.

City Gulls - Rooftop Nesters
00:01:41

Juvenile Glaucous-winged Gulls are taking flight over downtown Seattle. In Chicago, young Ring-billed Gulls are heading for Lake Michigan. And before long, juvenile Herring Gulls will be soaring over the Atlantic Ocean. More and more, some gulls are raising their families in the city. They nest on flat, sunny rooftops that are generally inaccessible to humans. When chicks like this Western Gull fledge, they’re soft brown, and won’t have adult plumage – that flashy white and gray or black crispness – until they’re four years old.

Barn Swallow, Natural Pest Control
00:01:45

Barn Swallows have adapted to nesting near people, and build their cup-shaped mud nests in barns or garages, or on protected ledges, often near each other. The good news? These twittery, flittery birds love to eat the insects that humans consider pesky.

Imagine: 60 insects per hour, a whopping 850 per day. That's how much each bird eats.

The Secretarybird of sub-Saharan Africa looks like a slim eagle set on the long, slender legs of a crane. Secretarybirds can fly but prefer to hunt on foot, walking over 20 miles a day and dispatching their prey with powerful kicks of their taloned feet.

Climate change poses a big threat to all life on earth, and birds are no exception. Garry George is the director of the Clean Energy Initiative for the National Audubon Society, and he says that wind turbines are essential to meet our carbon reduction goals. But they can also kill birds. Garry and his team at Audubon provide guidance on how to make wind farms safer for birds.

Voices and Vocabularies - Robin's Evening Song
00:01:41

During the day, an American Robin, a member of the thrush family, sings a lovely, familiar song of rich phrases. But as the sun begins to set, robin song takes on a different character. From sunset until dark, a robin adds ethereal whispered notes to its carol, creating a song of remarkable grace and complexity. In the high latitudes, where twilight lingers late into the evening, a robin may expand its daytime carols into a twilight symphony that continues for hours.

Voices and Vocabularies - Songs Long and Short
00:01:41

When a Sage Thrasher, perched on a clump of sagebrush, tips its head back to sing, the notes rush forth. They often sing non-stop for at least two minutes. In stark comparison, the song of this Brewer’s Blackbird lasts barely a second. And the Henslow’s Sparrow values brevity even more. But whether they’re long and drawn out or short and sweet, bird songs are all about the same things: territory and breeding.

Drinking on the Wing
00:01:35

Many birds drink while standing — dipping their beaks into a pond or birdbath, taking a beakful, and then tossing their heads back to swallow the water. But drinking on the wing suits swallows best. They walk awkwardly on the ground, and their long wings are cumbersome. So it’s far more efficient to grab a drink on the glide. This adaptation holds true for some other birds, too, including Common Nighthawks and swifts. Swifts have such short legs that they never land on the ground — so a sip on the wing is essential.

Western Tanagers Are Flashes of Bright Color
00:01:45

Western Tanagers dart from tree to tree, on the lookout for delicious bugs. They’ll find them by scanning the tree bark — or maybe snatching them from mid-air during flight — a tactic called hawking. Come winter, these lovely songbirds head south, where they fit right in with the other brightly colored tropical birds they’ll spend the winter with in Mexico and Central America.

Instrumental Bird Sounds
00:01:41

Birds communicate with a fascinating array of instrumental sounds, and nearly all are made with their feathers or bills. The territorial drumming of a woodpecker - like this Black-backed Woodpecker - is one example. American Crows clatter their beaks to make rattling sounds. And the remarkable drumming of a Ruffed Grouse is produced by a rapid beating of its wings.

Birds that Sound Like Cats
00:01:45

Named after their distinctive cat-like “mew” call, Gray Catbirds are mimic thrushes, related to mockingbirds and thrashers. They can imitate a wide variety of noises, from songbirds to mammals to frogs. Noisy and boisterous in the spring, a migrating flock of catbirds can fill a city park with sound.

Brooklyn's Blue Jays
00:01:37

Brooklyn’s Prospect Park covers more than 500 acres — many of them covered in trees. One bird species that calls the park home is the strikingly beautiful Blue Jay, which nests, forages, and roosts in trees. In the eastern US, you can invite Blue Jays into a small yard with just a decent tree or two. It’s the volume of branches and leafy habitat overhead that matter to the jays.

Bee Hummingbird
00:01:40

The Bee Hummingbird, found only in Cuba, is the smallest bird in the world. An absolute miniature, even among hummingbirds, it measures only two and a quarter inches long. Often mistaken for bees, they weigh less than a dime. The female builds a nest barely an inch across, and lays eggs about the size of a coffee bean.

The Eyes of an Owl
00:01:41

Peer into an owl's face – there is something almost human about its large, forward-facing eyes. The Great Gray Owl, which stands two feet tall and weighs 2 and 1/2 pounds, has eyes larger than those of most humans! Enormous eyes enable owls to see in near darkness. An owl's retinal anatomy is similar to that of cats, which rival owls in seeing in dim light. You can learn more about owls' eyesight from the World Owl Trust.

Chickadees Clean Up After the Youngsters
00:01:45

Imagine this Black-capped Chickadee flying toward its nest, carrying fresh insects for its chicks. A moment later, it emerges with a tiny white pouch in its bill. The chickadee drops the object into the vegetation below. That outgoing payload is a fecal sac, a remarkable adaptation found in nesting songbirds. Nestlings — often within seconds of being fed by an adult — excrete waste in tidy little sacs. Then the dutiful parent switches tasks, from meal delivery to waste management.

The native pinewood forests of the Scottish Highlands are home to many species, but among the most striking is the Western Capercaillie – the largest living grouse species. Their future in the highland forests is under threat. But a conservation task force headed by the Royal Society for the Protection of Birds and backed by landowners and the government is striving to reverse their decline.

What Are Birds Saying
00:01:27

A bird’s crest is made up of a slender array of feathers on top of its head. These feathers are a bit longer and can be spiked up or slicked back, depending on what the bird is trying to communicate. Even birds without crests, like crows or sparrows, sometimes puff up their short crown feathers.

A Drive Along on a Bar Ditch
00:01:32

In the rural Southeast, roadside ditches – known as “bar ditches” – carry on for miles. The term bar ditch probably comes from their construction, when dirt was "borrowed" to build up the road. The ditches are full of water and full of life, these narrow wetlands. Herons stalk the shallow water, stabbing at minnows. Common Gallinules, like this one, swim on the surface. Reeds and bulrushes provide cover for secretive marsh birds like King Rails. Red-winged Blackbirds flash crimson epaulets as they sing, and Boat-tailed Grackles offer their own rough music.

Great Horned Owl III
00:01:39

This Great Horned Owlet - about 2-1/2 months old and already as big as its parents - is quite well feathered, although its underparts remain downy. Its wing and tail feathers are developing nicely, and it has begun to make short flights. By mid-May, the owlet still relies almost entirely on its parents for food, and will stay with the family for months to come.

American Kestrel
00:01:45

The American Kestrel is the smallest, most numerous, and most widespread North American falcon. This bird is built for speed, its long pointed wings often bent back at the tip. While hunting, kestrels hover above an open field. These days, the lack of suitable nesting cavities, which limits American Kestrel populations in some areas, has lead to public interest in installing wooden nest boxes.

Pigeons, one of the most ancient of domesticated animals, feed their nestlings a peculiar, milky substance, straight from the adult’s beak to the baby’s throat. It’s called pigeon milk, a fat-rich substance loaded with antioxidants and immunity factors that enhance the survival of newborns — much like mammals’ milk does.

How Much Birds Sing
00:01:35

A typical songbird belts out its song between 1,000 and 2,500 times per day. Even though most bird songs last only a few seconds, that's a lot of warbling! A Yellowhammer, a European bunting, may sing over 3,000 times a day. But the Yellowhammer doesn't even come close to the North American record-holder, this Red-eyed Vireo. One such vireo delivered its song over 22,000 times in ten hours!

Piping Plovers are tiny, sand-colored shorebirds that nest on the beach. They’re threatened in much of their range. But plovers have gotten a boost from something rather surprising: hurricanes. Superstorm Sandy left behind plant-free, sandy beaches on barrier islands in New York and New Jersey, which actually offers better camouflage for nesting plovers. Where these hurricane-created habitats were protected, Piping Plovers have boomed.

First is The Western Tanager or Why Montana, a villanelle reflecting on why people choose a home. Then, In Houston examines the intimacy of quiet moments and the surprising sounds that can be heard when we really listen. And finally, Silas Fishing 1967 shows how connecting with even small moments in nature can have a transformational effect.

A Lost Hummingbird is Found Again
00:01:45

The Santa Marta Sabrewing is a hummingbird species so rare, they’ve only been documented twice in recent years. Native to the mountains of Colombia, they were officially described in 1946. No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to find them. Then in 2022, Yurgen Vega was studying the birds of a mountain range called the Sierra Nevada de Santa Marta. He snapped a photo of an unusual, large hummingbird – and the sabrewing was lost no more.

A pair of White-throated Swifts twists and turns, sailing through the air. Dashing headlong across the canyon toward an unyielding wall, the birds disappear at the last second into a slender crevice. This swift is aptly named — and doubly so. The White-throated Swift is among the fastest of all birds. And its lyrical, scientific name suits it perfectly: Aeronautes saxatalis - sailor of the air who dwells in the rocks.

The Early Bird
00:01:45

We've all heard that the early bird gets the worm. But research shows that birds dining early and heavily may lower their life expectancy. Socially dominant birds stay lean (and agile at avoiding predators) during the day, and then stoke up later, before a cold night. Subordinate birds have to look for food whenever and wherever they can find it, and carry fat on their bodies to hedge against unpredictable rations.

Then, a new Phoenix would rise from the ashes.

What’s a Field of Grass to a Bird?
00:01:45

Although a field of grass might not seem like valuable habitat at first, many birds have adapted to nest in grassland habitats and nowhere else. In North America, birds such as the Bobolink seek out grasslands to raise their young, deftly hiding their nests within the dense vegetation. Very few grasslands and savannas have been protected compared to the area that’s been lost, making them the most at-risk ecosystem on the planet. That means every acre of grassland remaining is even more precious — to birds, to plants, and to people.

House Wrens and Dummy Nests
00:01:37

There may be no busier bird during the nesting season than a male House Wren. Just a day or so after completing his spring migration from the tropics, the male House Wren claims a territory and checks out several potential nest cavities. And in each of these locations, he builds a starter nest using virtually anything twig-like to get the job done — from nails and bits of wire to paper clips and hairpins. The male House Wren stays at it until a female pairs with him. Then she picks one of the starter nests and takes over construction.

Raising the World’s Deadliest Bird
00:01:41

You might think the first bird species that humans raised in captivity would be a relatively small one, like a chicken. But evidence suggests that people in New Guinea reared the cassowary, often called the world’s deadliest bird, as much as 18,000 years ago, long before the domestication of chickens. The remains of cassowary eggs and bones at archaeological sites in New Guinea indicate that people gathered the eggs, possibly allowing the more mature eggs to hatch into chicks.

Spring Migration Across the Globe
00:01:41

Each spring, millions of birds head north. From Ecuador, beautiful Scarlet Tanagers fly to the eastern US and Canada, many traversing the Gulf of Mexico, an arduous journey. Across much of southern Europe, Common Nightingales – small thrushes with russet feathers – are arriving, having traveled northward from Africa across immense deserts. In northern Asia, petite songbirds known as Siberian Rubythroats — like this one — are arriving en masse, some winging their way across the South China Sea from the Philippines, others over the mountains from Thailand.

Great-tailed Grackle
00:01:45

Great-tailed Grackles live up to their name. The glossy black males trail their long, V-shaped tails behind them as they fly, almost like a plane towing a banner ad. And while not quite as flashy, the brown-feathered females have impressively long tails, too. Also known as the Mexican Grackle, this species lives in all sorts of habitats from the northern coasts of South America to the western U.S. Their ability to live in both cities and farmland has helped Great-tailed Grackles expand as far north as Iowa.

Brewer’s Sparrow, Sagelands Singer
00:01:41

One of the most musical and complex bird songs in the US is that of the Brewer's Sparrow. It's a veritable aria, ringing forth from the sagebrush of Eastern Washington's Columbia Basin. Shrub-steppe is disappearing from the interior west as it is cleared for irrigated crops. The quintessential drylands bird, the Brewer's Sparrow can survive for an extended period of time with no supplemental water, getting all the water it needs from seeds and arthropods.

The Eagle Eye

Magpies Help Each Other Remove Tracking Devices
00:01:45

Tracking birds can be tricky — even with GPS technology. Around 70% of bird species are just too small to carry a GPS battery. But recently, Australian scientists developed GPS trackers that looked like little backpacks, weighed less than a gram, could charge wirelessly and could be quickly released with a magnet. When the researchers tested the trackers on Australian Magpies, though, the birds managed to pinpoint a tiny weak spot in the backpack and helped each other peck the trackers off. This showed evidence of altruism, a rare behavior among birds.

A Kettle of Vultures
00:01:42

In the daytime, hot air rises as the sun heats the ground. The rising column of air is called a thermal, and it’s the perfect way for a Turkey Vulture to hitch a ride. Like an elevator to the skies, the thermal gently wafts the vultures upward. They move in a slowly ascending spiral around the thermal, rarely flapping and instead coasting on the breeze. When many vultures ride the same thermal, it’s called a kettle.

The Ruby-crowned Kinglet is one of the smallest songbirds on the continent, weighing in at just a little more than half a chickadee. Mostly green and hard to spot, it hovers in mid-air as it catches tiny insects. In early spring, the kinglet's rollicking song echoes from the forest edge in the lowlands. By late May, he is singing and nesting at mile-high altitudes in mountain forests.

Nest Building
00:01:45

Want to try building a nest? Consider this... An average American Robin weighs less than three ounces. An average person weighs 170 pounds, or 1,000 times as much as a robin. A robin's nest, made of grass and mud, weighs about seven ounces, so yours will weigh 450 pounds. You'll need to collect about 350 strands of grass, each about four feet long. And don't forget the mud: 150 pounds of it. You have five days to complete the job. That's 300 mouthfuls of mud.

Cuckoos - Tent Caterpillar Birds
00:01:39

One of two species of cuckoos in North America, the Yellow-billed Cuckoo, pictured here, lives in broadleaf forests throughout the East and riparian stands in the Southwest. They were common breeding birds in the Pacific Northwest as late as the 1920s, but then they disappeared. The Black-billed Cuckoo is a more northerly species that lives in dense woodland, even conifer forests. Cuckoos perch quietly and scan their surroundings for food. Hairy tent caterpillars, shunned by most birds, are often on their meal ticket.

From Bobwhite Coveys to Pairs
00:01:45

Throughout winter, Northern Bobwhites gather in groups called ‘coveys’ to search for food during the day and share warmth at night. These small quail arrange themselves in a circle, with their tails in the center and heads outward, huddled up like a wreath of plump birds to survive frost and snow. But as spring arrives, the coveys disband and bobwhites seek out mates. Males whistle from shrubs and tufts of grass, hoping to catch the attention of a female.

Monk Parakeets
00:01:34

If you live in the U.S., parrots might seem like ambassadors from far-off rainforests. Especially since the Carolina Parakeet, a native species once common in the South and Midwest, went extinct in the early 20th Century. But more and more parrots are finding a home here. Since the 1960s at least, Monk Parakeets have been free-flying and reproducing in the U.S. Over twenty introduced parrot species are now nesting in the US, with hotspots in Florida and California.

Camille T. Dungy on Nature and Motherhood
00:10:39

Writer Camille T. Dungy’s book Trophic Cascade deals with themes of nature and becoming a mother. The title is an ecological term, referring to the far-reaching changes on an ecosystem caused by the removal or introduction of a top “trophy” predator. In the case of Camille’s book, that “trophy creature” is her daughter. Camille performs three poems from Trophic Cascade reckoning with these changes to her own ecosystem.

Scientists have long thought that new species took a very long time to emerge. This thinking has now changed dramatically. On an island in the Galápagos, researchers Rosemary and Peter Grant discovered that a hybrid union of two distinct species of finch produced descendants different from any of the island’s known species — and the speciation happened in just two generations.

Kari Sasportas on Advocating for Autistic Birders
00:01:45

For Kari Sasportas, who helps lead the Feminist Bird Club of Boston, birding is a way to become absorbed in the sensations of the outside world —  something that can be difficult for them to do elsewhere as an autistic person with an auditory processing disorder. Kari advocates for making the birding world more accessible for neurodivergent people. While they have seen programs designed specifically for autistic children, Kari says it’s important to ask autistic adults what they want from birding, too.

A Natural Feast for Hummingbirds
00:01:45

Hoping to attract hummingbirds to your yard or balcony? One way is to grow native plants. Native plants provide cover, and they offer nectar in spring and summer. They also attract insects, the most important part of a hummingbird’s diet. Just add a source of water for drinking and bathing, and you’ll have a hummingbird haven. This Anna's Hummingbird is feasting on red-flowering currant.

Kingbirds Steal from Wasps
00:01:37

Kingbirds are robin-sized flycatchers that excel at plucking insects from the air. They’ll even tackle prey as big as cicadas. Finding naturally-camouflaged cicadas hidden among the leaves is hard work. But two species of kingbirds in Arizona found a shortcut — stealing them from cicada-killer wasps! The female wasps, nearly two inches long, paralyze cicadas and bring them to their burrows for their young to eat. The kingbirds have learned to ambush wasps carrying cicadas on the way back to their burrows.

Robins and Earthworms: The Backstory
00:01:45

When glaciers pushed south into what is now the U.S. around 20,000 years ago, they scraped off the soil layer and spelled the end of native earthworms except in the southern states. So the earthworm plucked by the robin in the park or on your lawn is probably a relatively new arrival, most likely a species Europeans conveyed to the Americas in plant soil or the ballast of ships.

A clean feeder is a life-and-death matter to some birds. To protect the birds at your feeder, clean it at least once a week, more often if necessary. Rake the ground underneath, too. Pine Siskins are especially prone to salmonellosis, a bacterial disease. You can learn more about feeding backyard birds at Cornell's AllAboutBirds. California Partners in Flight has more suggestions about feeding birds safely!

Melanin Makes Feathers Stronger
00:01:32

Many species have black feathers on the trailing edge of their wings, regardless of what color most of their feathers are. Birds as different as gulls, pelicans, storks, and flamingos all have black-tipped wings. These flight feathers are rich in a pigment called melanin. But melanin doesn’t just provide color. It also helps make feathers stronger. Feathers with melanin have a tougher layer of keratin, the same substance found in human fingernails, compared to feathers without. So the black feathers actually help protect a wing from wear and tear.

Birds Expanding the Human Imagination
00:01:45

Glenn Albrecht grew up in a “bird lover’s paradise” in western Australia. But when he saw how coal mining displaced communities, polluted the air and water, and decimated bird populations, Glenn lacked the words for his emotions. He created the concept of ‘solastalgia’ to describe the pain of witnessing environmental harm where you live. He imagines a possible future era, called the ‘Symbiocene,’ when human activity will, once again, be fully interconnected with the ebb and flow of the rest of nature and therefore cause no more destruction of life on Earth.

People often say that spring “bursts” forth. But this seasonal change isn’t like flipping a switch. It’s more like a series of waves breaking slowly. Robins and bluebirds return north in March. During April, more songbirds migrate north from the tropics, adding to spring’s growing chorus. As late as June, birds such as Willow Flycatchers and this Mourning Warbler arrive from South America. By this time, those early robins may be feeding their second brood. For them, spring has been bursting for over three months.

American Woodcock

At sunset, the male American Woodcock - a plump, robin-sized bird - walks slowly on short legs from the cover of the forest to a nearby clearing. After a few sharp calls, the woodcock takes flight. As it spirals upward, slim, stiff feathers at its wingtips create a curious twittering. At the apex of its flight, the woodcock circles, then descends in a slow spiral, putt-putting like a tiny car about to run out of gas. The woodcock's odd looks and sounds have earned it many colorful nicknames. The most memorable? Timberdoodle!

Zone-tailed Hawks of the American Southwest look a lot like Turkey Vultures. And they often soar among groups of Turkey Vultures. By consorting with vultures, Zone-tailed Hawks gain a distinct advantage as predators. While doves and lizards would quickly flee the flight silhouette of a Red-tailed Hawk, they seem to ignore the shadow of a vulture overhead. So floating among the vultures, Zone-tailed Hawks can sneak up on their prey undetected.

How Do Birds Brake from Flight?
00:01:45

Birds are often admired for their ability to fly. But braking just in time to avoid a crash landing is amazing by itself. How does a robin go from full-out flight to a dead stop at a tree? If we could watch in slow motion, we’d see it raising the angle of its wings higher and higher from the horizontal. A hawk dives a bit below where it wants to perch, then pulls into a steep climb, slowing its momentum. And this female Wood Duck will use a combination of raised wings and a bit of hydroplaning with her wide, webbed feet to land on water.

Drumming with Woodpeckers
00:01:45

Like a jazz player beating out a drum roll, a woodpecker uses its bill to rap out a brisk series of notes. Early spring resounds with the percussive hammering of woodpeckers. Their rhythmic drumming says to other woodpeckers, "This is my territory!" We also hear them knocking on wood when they carve holes in trees to create nest cavities or reach insects. For any woodpecker, it’s all about proclaiming a signal as far and as loud as possible. Look for Yellow-bellied Sapsuckers, like this one, in the Northeast and farther north, and Red-breasted Sapsuckers in the West.

Bushtits

Weighing about as much as four paperclips, Bushtits are smaller than many hummingbirds. And they take full advantage of their diminutive size. While larger insect-eaters forage on the upper surfaces of leaves, Bushtits hang beneath them, plucking all the tiny insects and spiders hiding out of sight. They pair off to nest. (This male Bushtit is working on his nest.) Where they live in Western suburbia, a flock of Bushtits can help rid a garden of harmful aphids and scale insects. Shun the pesticides and let these guys do the work!

But genetic data revealed that Magellanic Plovers are neither plovers nor doves — they’re the only species in the family Pluvianellidae. Genetically speaking, they’re one of a kind.

The World's Most Abundant Bird
00:01:42

An estimated 1.5 billion Red-billed Quelea live in Africa today, making them the most abundant of all wild birds. The sparrow-sized Red-billed Quelea flock together in groups so large, from a distance they appear to be clouds of smoke. Red-billed Quelea are in the weaver family and create tens of thousands of carefully woven nests in their enormous colonies.

Black Swifts Reach for the Moon
00:01:42

Tracking devices revealed that Black Swifts spent over 99% of their time in the air during the winter, almost never touching the ground for months. What’s more, the swifts flew to incredible heights, reaching the highest altitudes on nights when the moon was full – sometimes over 13,000 feet! It’s the first time scientists have seen birds changing their altitude along with the cycles of the moon.

Adaptations for Flight
00:01:45

Birds evolved not only wings, but many other adaptations that make it possible to fly. Feathers provide insulation, waterproofing, and a lightweight means to become airborne. Birds have honeycombed or hollow bones, reducing body weight. And instead of weighty jawbones and teeth, birds evolved a light and serviceable beak made of keratin. Most birds consume energy-packed foods rich in calories – like seeds, fruits, and meat, which add as little as possible to a bird’s payload. And what they eat is processed rapidly, so they aren’t weighed down by waste.

Birds Move from Fresh to Salt Water
00:01:42

To hear a Common Loon in the wild during summer, you’ll need to find a northern, freshwater lake where a pair is nesting. But to find that same Common Loon in winter, you’ll likely need to look on a saltwater bay. This shift from fresh to salt water would kill most animals. But loons — along with many ducks and other water birds — have evolved to make that move. It’s possible that breeding adults nest on fresh water in order to save their energy for raising chicks.

Sage Thrasher and Sagebrush
00:01:45

The glorious song of the male Sage Thrasher rings out every spring from tracts of sagebrush throughout the West. Sagebrush was once widespread in the Great Basin region, and so were the thrashers. But huge areas of sagebrush were turned into alfalfa and potato farms, and the songs of the thrasher aren't so common today. Sagebrush badly needs advocacy. The Important Bird Areas program works to protect key habitats for birds.

To Beta or Not to Beta
00:01:42

Male Lance-tailed Manakins pair up to perform choreographed courtship displays for females. Known as cooperative courtship, it involves one alpha male and one beta male, who are not closely related, working together to attract the female. While it might not seem like a good deal for the beta male, the betas gain experience in courtship that could come in handy when they attain alpha status.

Diving Birds Are Dense
00:01:37

While many birds have hollow bones that make flying a breeze, diving birds are built differently. The bones of divers such as Common Loons are denser than those of songbirds and other expert fliers. With a lightweight skeleton, they’d be too buoyant to dive and chase fish. Instead, loons can kick their powerful legs and webbed feet to swim 200 feet or more underwater!

Dreading the Terns
00:01:45

In June of 2022, Adé Ben-Salahuddin worked as a volunteer research assistant on a tiny island off the coast of Maine at a Common Tern breeding colony. Every once in a while, the colony would suddenly go dead silent as all the adult terns took flight and dove over the rocky cliffs, returning soon afterward. This strange behavior is called a “dread,” and sometimes occurs without a predator nearby. It remains unclear why terns do it.

Northern Saw-whet Owl - A Bird with a Lot to Say
00:01:32

For such a small owl, the Northern Saw-whet has a lot to say. And a lot of ways to say it. Males weigh about as much as an American Robin. And they send out at least 11 different calls, including “toot-toot-toot” advertising calls, from late January through May. The rate of calling is partly determined by the nighttime temperature. And perhaps to keep other Saw-whets out of a food-rich territory, males may toot more frequently when their favorite prey, white-footed mice and deer mice, are plentiful.

Rough-legged Hawk
00:01:45

After breeding on Arctic cliffs and tundra hillsides in summer, Rough-legged Hawks winter throughout the Northern Hemisphere. Open country is their ideal territory, where the small rodents they depend on are usually so plentiful that the hawks have enough to eat. But the rodents are cyclic, with lower populations in some years, and in those winters, Rough-legs may migrate farther and be more abundant in the contiguous United States.

Common Eiders Favor Close Relatives

Some species of birds try to save energy by tricking others into incubating their eggs. But if the parasitic female is a related species, she may have an advantage. After studying the nests of Common Eiders, such as the one pictured here, researchers at the University of Gothenburg in Sweden determined that trickery among close relatives of the nest owners caused no aggression. But the attempts of unrelated females often resulted in conflict.

New Sam Peabody
00:01:41

In late winter, White-throated Sparrows erupt into song, easily set to human words: “Old Sam Peabody, Peabody, Peabody.” Or “Oh, sweet Canada, Canada, Canada.” But something changed since those classic memory aids were coined. Sixty years later, the bird sings a simpler, shorter song. Bird song, like human language, changes. By the 1960s, the bird’s longer song became rare. Researchers suggested that the “classic” song had — for some unknown reason — died out, to be replaced by a shorter version.

Annakacygna – The Ultimate Bird
00:01:45

Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers who first described these species to dub them “the ‘ultimate bird’ that ever existed.”

Wilson’s Phalarope
00:01:41

If any bird is an anomaly, it’s the Wilson’s Phalarope. In a birdbook, Wilson’s Phalaropes are found among the sandpipers. But they forage while swimming. Spinning like tops, they create an upwelling, pulling food to the surface. The breeding of Wilson’s Phalaropes is anomalous, too. Females are the brightly colored sex, and courtship roles are reversed: female phalaropes compete for males, and, once they lay eggs, leave all parental duties to the males. In common with many birds, though, Wilson’s Phalaropes face conservation challenges.

Most wrens in North America are small, furtive birds that stay deep in the vegetation. But the Cactus Wren is large, bold, and brassy. These wrens are well adapted to the desert and can get all the moisture they need from their food. Cactus Wren nests are a regular sight in their range of dry habitats from West Texas to California. The nest looks like a football made of twigs, stuck horizontally in a thorny tree or cholla cactus. It’s easily seen but well guarded by the spiky vegetation.

00:01:45

For some birds, love is in the air. When a pair of White-throated Swifts wants to get to know each other, they meet up — on the wing — high above the ground. The birds grasp one another and, clinging together, tumble downward, for over 500 feet. Just before striking the earth, they separate, flying nonchalantly back up the canyon wall. Visit a Western canyon, and you might see a pair of swifts literally falling in love.

That’s not a distant dog barking. It’s a Black Skimmer in flight, at the Chincoteague National Wildlife Refuge in Virginia. This striking, black-and-white bird with a red bill and red feet has a most unusual way of feeding. It flies low along the surface of the water with its beak open. Closely related to terns, skimmers nest on sand islands in closely packed colonies. They depend on undisturbed islands and abundant small fish in coastal lagoons for their survival.

When smaller birds join forces to ward off larger birds, it's called mobbing. This behavior — like calling your family for help — is used by many bird species. The best time to observe mobbing is spring and early summer, when breeding birds are trying to protect their nests and young. Birds including swallows, blackbirds, and even these American Crows, seen here mobbing a Red-tailed Hawk, know that there is strength and power in numbers. And they've learned to join forces to protect themselves.

House Finches are evolving rapidly and visibly. In 1941, some captive House Finches from California escaped near NYC. They spread rapidly and are now found across most of the US. We know the finches have evolved, because those that survive differ from their parents. Size is one example. Male House Finches in recently established populations are larger than the males that escaped. Females have become smaller and survive better than larger females as nestlings. Evolutionary changes are occurring visibly all around us.

Turkey Vultures and Gas Pipelines
00:01:38

Do vultures detect carrion by sight or by smell? The lightbulb moment came to ornithologist Kenneth Stager when a Union Oil employee told him of vultures congregating at the spots along pipelines where gas leaks were occurring. Why would they do that? Because a key ingredient in the odor of carrion is ethyl mercaptan — the same substance companies add to odorless natural gas in their pipelines, so they could smell if there was a leak. So now we know that vultures can spot carrion by either sight or smell.

Birdhouses in Turkey
00:01:41

It’s easy to imagine that putting up a birdhouse or nestbox is a relatively recent practice. But in Turkey, it has a long history. Since at least the 13th century and continuing through the period of Ottoman rule, birdhouses were placed on all sorts of structures: mosques (like this one – the Yeni Valide Mosque in Üsküdar, Istanbul, Turkey), schools, libraries, houses, tombs, bridges, and palaces. In this culture, birdhouses were viewed as an expression of love and compassion for animals. The Ottomans even endowed charities to provide food and water for birds and to care for sick birds.

Clever Nuthatches
00:01:40

Of the four nuthatch species living in the United States, the most common are the Red-breasted Nuthatch, seen left here, and the White-breasted Nuthatch, on the right. The nuthatch's insistent call matches its aggressiveness. As it works its way down a tree trunk, the nuthatch can spot-and eat-all the tasty morsels missed by the rest of the birds working their way up the tree.

Birds Winter at the Salton Sea
00:01:41

California's Salton Sea is hot and smelly - and it's also a Mecca for thousands of wintering birds. This inland sea formed when the Colorado River breached floodgates in 1905, forming a lake 45 miles long. The lake has diminished in size and greatly increased in salt concentration, but a single introduced fish - the African tilapia - persists in abundance. Seabirds visit the Salton Sea to feed on them. The smell comes from occasional massive die-offs of the fish, so abundant that their bones make up the shoreline. Every winter, the salty waters support hordes of water birds, including shorebirds, herons, cormorants, pelicans, and waterfowl. Check it out!

Northern Cardinal - Meet the Cardinal
00:01:45

Is there any doubt about the identity of America's best known red bird? Surely it's the cardinal or, as you'll find it in a bird book, the Northern Cardinal. The beautiful bird seen on so many bird feeders takes its name from the cardinals found in the Vatican, whose hats and robes are red. Only the male cardinal — seen right here — is red; females are a tasteful olive-brown with red highlights. Share this show with someone who likes cardinals. Thanks!

Common Poorwills Can “Hibernate”
00:01:36

Common Poorwills don’t sing much when the mercury drops. But they can do something else that is remarkable. As the winter cold deepens, these petite members of the nightjar family can enter a hibernation-like state — and stay like that for hours — or even weeks! Scientists call it torpor. It happens when an animal slows its body functions to conserve energy and heat.

Woodpeckers Love Ants

Woodpeckers, as a group, eat far more ants than most other birds do. Many other vertebrates tend to avoid ants because of their stings or because of the noxious chemicals they contain, like formic acid. But woodpeckers just love them. A Pileated Woodpecker’s diet may be up to 50% ants!

Dave Mull is not your typical birder — he's a professional skateboarder, or a “skatebirder” as he puts it. He brings binoculars with him when he skateboards and doesn’t mind putting his board down to check out a bird. But the birds aren't really a distraction for Dave. Tuning into his surroundings, including the birds, helps him stay in the zone and provides inspiration for tricks.

Identifying a Bird in Flight
00:01:41

One of the most difficult skills to pick up as a birdwatcher is how to identify birds in flight. You have to sort through a series of visual clues all at once, at high speed: silhouette, wing shape, how fast it flaps, and patterning. An experienced birder will take in all these and other clues that are hard to put into words — and might say something like: “Look! A hawk! Must be a Cooper’s Hawk — it has that giss.” In other words, it has all the telltale signs. But where did this bit of birdwatching slang originate?

Thick-billed Euphonia - Deceitful Mimic
00:01:32

Northern Mockingbirds can learn to mimic the sounds of just about any bird. They mimic to show off, not to deceive. But this Thick-billed Euphonia, a tiny songbird in South America, employs what scientists call “deceitful mimicry.” When frightened by a predator near its nest, a Thick-billed Euphonia imitates the alarm calls of other birds nesting nearby. This stirs them into action as they rush in to harass the predator. The euphonia, meanwhile, sits tight while others do the dirty work.

Yellow-rumped Warbler - The Winter Warbler

By winter, most warblers have migrated south. But the Yellow-rumped Warbler, which birders affectionately call “butterbutt” is a lesson in adaptation, notes Bryan Pfeiffer, a writer, naturalist, and educator who lives in Vermont. “In winter, when most of their kin are enjoying insects in the tropics, Yellow-rumps are finding food across parts of the West, the southern U.S. and north into New England,” he says. “With insects in short supply, the Yellow-rump turns to fruit . . .”

The Music of Herring Gulls

For some of us, it’s hard to get excited about gulls. But they are just as fascinating – and have as much to tell us – as other birds. Take the Herring Gull, for example. Its appearance is striking, and its voice is unforgettable. Along the Atlantic coast of North America, the nesting population of Herring Gulls numbers in the hundreds of thousands. But as recently as 1900, feather and egg hunters had wiped out virtually all nesting Herring Gulls south of Maine. Fortunately, conservation laws have enabled the gulls to recover.

Bohemian Waxwings Wander South

In winter, when snow blankets the northern states, nearly all of the songbirds that graced the days of summer are gone. But there’s one special winter visitor that fills the absence: the Bohemian Waxwing. In autumn, waxwings wander south from the boreal forest into the northern states and along the Rockies. Sometimes, they venture even farther south. In fact, it’s this itinerant life that earned them the name “Bohemian.”

Long-tailed Ducks are back for the winter from the north, where they nested on tundra ponds and marshes. These diving ducks spend the winter in deep salt water, often in sheltered bays. Long-tailed Ducks are far more vocal than most ducks, a feature that has earned them a host of charming nicknames, including "John Connally," "My Aunt Huldy," and, from the Cree language, "Ha-hah-way."

National Audubon's Corkscrew Swamp Sanctuary is birdy at any time of year. But in winter, this mixture of cypress swamp and pineland comes alive with migratory songbirds. On a warm, sunny morning, birds are active all around, from the tops of the tall cypresses to the shrubs along the boardwalk. An Eastern Phoebe, after spending the summer in Pennsylvania, calls from a dead branch over the water. A Palm Warbler, all the way from Ontario, moves through the undergrowth. And this Blue-gray Gnatcatcher, having migrated from a similar swamp in Georgia, forages in a willow. Many birds find the habitats they need in the Corkscrew Swamp Sanctuary.

For small songbirds, surviving a cold winter night can be challenging. Their bodies lose heat faster than those of larger birds. So little birds have found resourceful ways to stay warm — like huddling close together with other birds. But the Verdin, a tiny bird of the Southwest, does something few other birds do to keep warm: it builds extra nests to roost in, in the winter.

There’s no mistaking this striking hawk for any other; the front of its body glows bright chestnut, the back boldly spangled black and white, the shoulders, that same blazing chestnut. Roughly crow-sized, Red-shouldered Hawks are found throughout the eastern U.S., retreating from the north in winter. Distinctive populations inhabit Florida and California west of the Sierra Nevada.

A close look at this Red Crossbill reveals a curious adaptation. The long tips of the upper and lower bill don't meet, but instead cross over each other. The Red Crossbill bites between the scales of a cone and pries them apart by opening its bill, then dislodges the seed with its tongue. Red Crossbills search for cones on the tops of the trees, climbing around using their feet and bills, much like parrots. And strangely, they’ll breed in winter, if the cone crop is good enough.

Attu and Its Island-hopping Rock Ptarmigan
00:01:44

Attu, at the western end of Alaska’s Aleutian chain, is home to the Rock Ptarmigan. Although grouse are not long-distance fliers, Rock Ptarmigans can cross open water, so they occur from one end of the Aleutians to the other. They are supremely adapted for high latitudes, with thick feathers, each with two shafts. During winter, even their toes become feathered. They ride out blizzards by burrowing deeply into fresh powder snow and roosting there. When spring finally arrives, the snow-white male will flutter into the air, then glide to earth while calling loudly. He fans his black tail in spectacular display before the female. And a new year begins!

All it takes is a breeze from the wind, or from flying, to move all that heat away from the surface of the feathers.

The Scaly-breasted Wren lives in Central and South America, and has a lengthy song of whistled notes separated by pauses. By analyzing song recordings, researchers found that Scaly-breasted Wrens can precisely measure out pauses  — even as they increase to several seconds. The findings suggest that the wrens have an internal metronome as accurate as a highly-trained musician playing a solo.

But it's not certain if the "mobbers" hope to drive away the predator, or simply draw attention to the threat.

A Bird Walk 65 Million Years Ago
00:01:41

For today’s bird walk, we’re going to need binoculars, sunscreen, hiking boots, annnnnd a time machine. Let’s set our course for the late Cretaceous Era, 65 million years ago. Stay alert! There are dinosaurs all around us, of all sizes — and appetites — including some of the earliest birds, like this Ichthyornis.

Of Grouse and Gizzards
00:01:45

During winter, the Greater Sage-Grouse is wholly reliant on its namesake species — sagebrush — for both shelter and for food. Scientists call this bird "sagebrush obligate," meaning it needs this plant to survive. In the spring, its diet shifts to insects and plants, as it gets ready for the most fantastic mating show in the west — the lekking season.

Downy and Hairy Woodpeckers
00:01:45

These Downy and Hairy Woodpeckers appear nearly identical, but the Hairy Woodpecker is larger than the Downy, with a distinctly longer bill. And it doesn't have the black spots on its outer tail feathers like the Downy. But even if you can’t observe these spunky birds, you can identify them by listening carefully. The call of the Downy Woodpecker is soft and downy, like a duvet. The call of the Hairy Woodpecker is loud and hairy, like a heavy metal band!

Clark’s Nutcracker and the Whitebark Pine
00:01:45

Clark’s Nutcracker is a clever corvid that has a special relationship with a tree called the whitebark pine. The tree’s cones don’t open on their own, and Clark’s Nutcracker is one of the few species that can pry them open. When the nutcrackers cache the seeds for the winter, they’ll leave a few behind, helping spread the next generation of whitebark pines.

Wing-clapping
00:01:36

For most birds, wings are for flying. But for Rock Pigeons, they’re also for clapping. When the pigeons erupt into flight, some may slap their wings together above their bodies in a “wing clap.” A male Rock Pigeon will also do this when courting. Short-eared Owls, like this one, have evolved wing-clapping, too. When a male displays to a female or attempts to warn off an intruder, he snaps his wings together below his body in a burst of two to six claps per second, producing a sound that sounds remarkably like . . . applause.

Puffling Patrol
00:01:37

Just off the southern coast of Iceland, the Westman Islands are home to many of the country’s several million Atlantic Puffins. When puffin hatchlings, known as pufflings, get confused by the lights of the city, volunteers of all ages search for wayward pufflings on the street and bring them in for health checks. After the puffins get the green light, the volunteers release them along cliffs and beaches.

Wilson's Warblers Benefit from Shade-grown Coffee
00:01:45

Early this fall, the tiny Wilson's Warbler began its long migration to Belize, where it winters. Navigating by the stars, the 1/4-ounce bird made a series of night flights spanning more than 2500 miles. This warbler returns to the same coffee plantation each year. Taller trees that shade the coffee are a winter home for many migrants from North America.

By buying shade-grown coffee, you can help migratory birds, including the Wilson's Warbler.

Diving Birds – Below the Surface
00:01:35

By December, an array of diving birds that nested at far northern latitudes are wintering on temperate waters across the continent. If we could watch them under water, we'd see this Common Loon racing like a torpedo. A goldeneye dives under water and swims about 10 feet from the surface, while scoters get down to 30 feet in search of clams and mussels. But if one bird stands out as the most beautiful diver, it has to be the Long-tailed Duck. Propelling itself beneath the surface with its wings, it seems to fly through the water, sometimes to depths of more than 60 feet!

Strange Places for a Nest
00:01:45

Birds are resourceful. Wherever they live, even in the biggest cities, they find clever places to build their nests. An initiative from the Cornell Lab of Ornithology called Celebrate Urban Birds, once asked people to share the funkiest and funniest places they’ve seen a bird nest. Among the highlights were a family of robins set up shop in a coiled cable hung near a welding rig, a wren nest in an old car motor, and a tiny hummingbird nest perched precariously on an outdoor string lightbulb.

Are Northern Forest Owls Coming South This Winter?
00:01:37

The boreal forest stretches across Canada and Alaska, a huge expanse of woods, wetlands and wilderness. And it’s full of magnificent forest owls that depend on mice and other rodents for food. Those populations can boom and bust, so in lean years, hungry owls often fly as far south as the northern U.S. to find food.

The Woodcock’s Silly Walk
00:01:45

When it comes to silly walks, no bird outdoes the American Woodcock’s one-of-a-kind strut. It goes like this: take one step forward, then rock your whole torso forward and back a few times before sliding another foot forward — all while keeping your head perfectly steady. It looks like a bird with an undeniable sense of rhythm. It’s not entirely clear why woodcocks walk this way. It’s another of the bird world’s little mysteries — and one of its grooviest dance moves.

Dowitchers Get a Second Wind
00:01:36

The two American species of dowitchers, Long-billed and Short-billed, are similar in appearance but have distinctive calls. And they’re some of the continent’s most dramatic songsters. On their northern breeding grounds, Short-billed Dowitchers ascend as high as 150 feet in the air then glide slowly earthward, singing. At the end of the glide, they may take off again for another bout of song.

New Homes for Cockatoos
00:01:40

The alpine forests of Australia’s southeast are home to an iconic pint-sized gray parrot with a bright red mohawk, and a call that’s been described as a “flying creaky gate”. The Gang-gang Cockatoo has seen significant habitat loss in recent years, especially after the 2020 wildfires. It’s now listed as an endangered species. A new national working group is coordinating recovery efforts. Researchers and community scientists are trialing an innovation on the Gang-gang population called the “Cockatube” — a PVC tube designed to host a cockatoo nest.

Why Birds' Feet Don't Freeze
00:01:45

Have you ever watched ducks walking around in freezing temperatures and wondered why their feet don't freeze? And how do birds, including this Northern Flicker, sit on metal perches with no problem? Birds' feet have a miraculous adaptation that keeps them from freezing. Rete mirabile — Latin for "wonderful net" — is a fine, netlike pattern of arteries that interweaves blood from a bird's heart with the veins carrying cold blood from its feet and legs. The system cools the blood so the little blood that goes down to the feet is already cold, so the birds don't lose much heat. The small amount that goes to the feet is likely just enough to keep the feet from freezing.

The Avocets of Bolivar Flats
00:01:43

The shallow waters and wide mudflats of the Bolivar Flats Shorebird Sanctuary northeast of Galveston, Texas, are alive with thousands of gulls, terns, and shorebirds. American Avocets are often among the most abundant birds, with 5,000 or more here most winters. The avocets have sensitive bills that curve upward. As they wade, they sweep their heads back and forth and snap up the tiny crustaceans that touch their bills. This tactile feeding method is unique among the birds here. The Bolivar Peninsula is famous for its big flocks of water birds and concentrations of migrating songbirds. Both National Audubon and American Bird Conservancy have designated it an Important Bird Area, or IBA.

Spark Bird: Maya Higa and Bean
00:01:45

When Maya Higa started interning at a zoo, she wasn't especially into birds — until she began rehabilitating a Red-tailed Hawk named Bean. Meanwhile, Maya was doing live-streams of herself singing and playing guitar on the website Twitch, just for fun, to a pretty small audience. The video went viral, and Maya's audience grew from there. Thousands of viewers watched Bean's rehabilitation on her streams, forming a bond with the bird. And this reminded Maya of her education work at the zoo. She has since founded the Alveus Sanctuary, a nonprofit animal sanctuary and virtual conservation education center.

Titmice Lead the Way
00:01:36

In winter, many songbirds join flocks made up of multiple species that travel around looking for food, benefitting from safety in numbers. But a bird flock that doesn't move in the same direction soon scatters to the wind. It turns out that the Tufted Titmouse, a small gray songbird, is often the one leading the flock. Researchers studying the flight paths of flocks found that the paths taken by the titmice best reflected the direction of the group as a whole, compared to other species in the group. This was especially true when the flock moved quickly between sites, when staying organized is key.

Snake-Eagles Are Awesome
00:01:45

When a soaring Short-toed Snake-Eagle spots a delicious snake, it swoops down, grabs it with its talons, then tears off the snake’s head. Still on the wing, it swallows the entire snake, head first. Smaller than Bald Eagles, they live mainly in Africa and have legs and toes covered in thick scales to protect them from bites. Snake-Eagles take on some of the swiftest and deadliest snakes in the world, like cobras and black mambas.

Molly Adams on Birding with Long COVID
00:01:45

For Molly Adams, the founder of the Feminist Bird Club, getting COVID didn’t just mean a week or two under the weather. Like other people with long COVID, they’re continuing to have chronic symptoms after the viral infection. Fortunately, before COVID they had learned about a technique called atlasing — observing birds closely to figure out if they’re breeding in a certain habitat. The observations become part of a record called a breeding bird atlas. Molly says atlasing is a more soothing, slowed-down approach to birding and involves getting to know birds as individuals.

Bird Names in Meskwaki

The poet Ray Young Bear writes in both English and Meskwaki, his first language. He says that the task of passing on Indigenous languages feels especially urgent now as linguistic scholars predict the loss of languages. 

The Meskwaki language is rich with bird names, like Tti Tti Ka Kwa Ha, the name for the robin, which emulates the bird’s song, he says. After decades of creating poems, novels, and songs, Ray Young Bear has dedicated himself to preserving and teaching his language and culture.

Return of the Snowbird
00:01:41

You may see Dark-eyed Juncos in the summer, but come fall, many more — those that have been nesting in the mountains or farther north — arrive to spend the winter. These juncos often visit birdfeeders for winter feasting. Dark-eyed Juncos forage on the ground. The flash of white tail-feathers when one is alarmed alerts other members of the flock, and is also used as part of the courtship display.

A bird’s bill is an incredible multi-tool — good for preening feathers, building a nest, self-defense, scratching, displaying, building a nest, and egg-turning. And a bill must be the right size and shape for the bird’s diet, whether that’s probing for worms, cracking open seeds, or tear apart prey.

Partial Migration - Killdeer Play Leap Frog
00:01:45

The cries of a Killdeer are familiar across most of the US during spring and summer. But where do they go in winter? Killdeer that breed in the southern half of the US and along the Pacific Coast are year-round residents. But those that breed in the northern US and Canada, where winter conditions are more severe, migrate south to Mexico and Central America. Because the northern Killdeer fly south — right over the region where other Killdeer reside year-round — they are known as leap-frog migrants.

Bears at the Bird Feeder
00:01:34

In bear country, food left outside or uncovered trash cans can become irresistible targets for bears looking for a quick snack. But even if you’ve put away any human food, don’t forget about bird feeders. Bears are omnivores and won’t hesitate to grab a bird seed snack. The New York State Department of Environmental Conservation recommends that people take down bird feeders between April 1st and November 30th, when black bears are most active. During the winter, the bears return to their winter dens and bird feeding can resume.

Geese in V-formation
00:01:44

Autumn…and geese fly high overhead in V-formation. But what about that V-formation, angling outward through the sky? This phenomenon — a kind of synchronized, aerial tailgating — marks the flight of flocks of larger birds, like geese or pelicans. Most observers believe that each bird behind the leader is taking advantage of the lift of a corkscrew of air coming off the wingtips of the bird in front. This corkscrew updraft is called a tip vortex, and it enables the geese to save considerable energy during long flights. The V-formation may also enhance birds’ ability to see and hear each other, thus avoiding mid-air collisions. Small birds probably do not create enough of an updraft to help others in the flock and don’t fly in vees.

Consider three species of raptors: the Barn Owl, Peregrine Falcon, and Osprey. They’re on every continent except Antarctica. Each has a specialized hunting prowess distinct from the other. They can fly great distances. And like many birds of prey, they mate for life. The Barn Owl, pictured here, has long been considered the single most widespread land bird in the world. But Ospreys and Peregrines have proven equally adaptable.

Boreal Chickadees Stay Home for the Winter
00:01:43

Boreal Chickadees live in the boreal forest year-round. How do they survive the harsh winter? First, during summer, they cache a great deal of food, both insects and seeds. Then in fall, they put on fresh, heavier plumage. And their feathers are denser than most birds', creating a comfy down parka. Most impressive? The chickadees lower their body temperature at night from 108 degrees to just 85 degrees, conserving their stores of insulating fat. Hats off to the Boreal Chickadee, a truly rugged bird!

For biologist and writer Wenfei Tong, the line between people and animals has always felt fuzzy — or maybe feathery, in the case of birds. Wenfei loves to highlight commonalities we share with birds, like how young adult Acorn Woodpeckers sometimes stay with their parents if there aren't good territories available for them to move into right away. She thinks that seeing ourselves in birds could be a boon for conservation.

Screech-owls are opportunistic diners. In the Pacific Northwest, they’ll prey on small birds, crayfish, large ants, or earthworms. In Arizona, pocket mice and pack rats. And in Ohio, biologists who noticed a fishy smell around Eastern Screech-Owl nest boxes found the remains of dozens of shad. It’s clear that screech-owls may be a consistent nocturnal predator on fish, especially in cooler months, when other prey are dormant.

Pulling Rank at the Birdfeeder
00:01:42

Birdfeeders full of seeds or suet can spark nonstop action. Chickadees flitter in and out. Finches expertly crack one seed after another, while jays, doves, woodpeckers and sparrows all join the flurry. This might bring to mind a neighborly picnic — but it’s not quite as friendly. At any given moment, there’s a distinct hierarchy in effect. More dominant birds are usually able to displace lower-ranking birds. But not always! The next time you’re watching a birdfeeder, try to figure out who’s in charge.

Providing Homes to Purple Martins
00:01:45

In the Southeast, on the lands of the Cherokee, Chickasaw, and Choctaw, Purple Martins nested in dried gourds hung up by Native Americans. This relationship might have developed because Purple Martins defend their turf, says Kelly Applegate, a tribal member and Commissioner of Natural Resources for the Mille Lacs band of Ojibwe. White settlers copied the practice and put up gourds and birdhouses, too. But they also cleared forests where martins once nested and introduced House Sparrows and starlings that drove them out of woodpecker holes. Purple Martins now depend almost entirely on artificial nest boxes to survive. Kelly is encouraging people to provide homes for martins.

A fledgling Great Horned Owl calls to be fed. Judging from the young bird's persistence, the parents seem to be responding only with calls, not with food. These entreaties can go on for weeks. Both parents let the fledgling know that it's time for him to feed himself. They've been bringing voles and rabbits for months. Silence and surprise are keys to the owls' success as hunters, so it's hard to imagine the juvenile Great Horned Owl improving his chances by being so vocal!

Who’s Afraid of Corvids?
00:01:45

Of all the birds out there, the corvid family — the crows, ravens, and jays — might have the spookiest reputation. But this idea that corvids are spooky is far from universal — it's mainly in the Western world, as corvid researcher Kaeli Swift explains.

Frigatebirds - Seabirds That Can't Get Wet
00:01:37

Frigatebirds are seabirds, but one thing you’ll never see is a frigatebird floating on the ocean. Why not? Because their feathers, unlike those of nearly all other seabirds, are not waterproof. Instead, frigatebirds are masters of staying aloft. They soar above the ocean, riding a complex roller coaster of air. Intentionally flying into a cumulus cloud, which has a powerful updraft, they may rise as high as 2.5 miles into the frigid atmosphere. From this high point, frigatebirds — such as these Great Frigatebirds — can glide more than 35 miles without flapping their wings. Which is how these seabirds survive over the open ocean.

Designing a Spider Web to Evade Bird Collision
00:01:45

One of the lesser known hazards of a bird’s life — when flitting from shrub to shrub — is collision with spiders’ webs. And when a bird flies through a web, it’s the spider’s hard work that takes the hit. It can take a spider an hour just to repair the damage and get on with the task of snaring its next meal. Some spiders have evolved a behavior to give birds advance warning of their webs. They weave into the structure visible designs of white, non-sticky silk, called stabilimenta. These make it easier for birds to see it — and avoid it.

The Five Birds You’re Scared Of
00:01:45

Author and bird enthusiast Ashley C. Ford says that it’s good to have a list of at least five birds that you’re scared of — like the six foot tall cassowary — just to keep you honest. “It's very important to humble yourself and to understand where you actually lie on the food chain,” she says. But despite the goose’s mischievous reputation, she’d never have them on her list. “I grew up in the Midwest,” she says. “And I know personally I'm not scared of no goose.” Hear more of Tenijah Hamilton’s conversation with her birding heroes, Ashley C. Ford and Tracy Clayton, on the Bring Birds Back podcast.

Geese Whiffling in for a Landing
00:01:41

Looking at a Canada Goose, you might not think their bodies are designed for fancy flying. But watch as a flock of geese comes in for a landing at a lake and you might be surprised. If the flock comes in too fast or too high above the water, geese have a little trick to slow themselves down for a safe landing. The geese stop flapping and then quickly roll their bodies upside down, while twisting their long necks the right way up. Finally, they rotate again to right themselves just in time to gently splash down. It’s a maneuver called whiffling. It seems to help the geese slow down quickly – but sometimes it might just be for fun.

Meet the Blue Jay

If we had to pick one bird’s voice to symbolize our Eastern woodlands, the Blue Jay’s voice would likely be it. And as a frequent visitor to back yards and bird feeders, the Blue Jay is among the most recognized birds of the region. Nearly a foot long, Blue Jays can be loud and assertive when they approach a bird feeder, pushing smaller songbirds aside. But when nesting, the same jays can sneak to and from their nests with uncanny secrecy.

Spark Bird: Kenn Kaufman
00:01:45

As a young child, Kenn Kaufman ventured into his neighborhood in search of the tigers, bears, and dinosaurs, but quickly found that Indiana doesn’t have those. So he set his sights on the next best thing: figuring out which birds were in his family’s yard. Though he’s now a world renowned birder and field guide author, he says his progress was slow. Today’s novice birders have access to mobile apps and websites that put photos, bird calls, and range maps at your fingertips. But whatever tools you choose, Kenn says there’s no substitute for getting outside and experiencing the birds for yourself.

Powder Down
00:01:35

Hidden below the outer breast feathers of herons, pigeons, doves, tinamous, bustards and some parrots are patches of special down feathers. These feathers are never molted, and they grow continuously. The tips break down into a dust the consistency of talcum powder. Using a fringed claw on its middle toe, a heron collects some of the dust—or powder down—and works it into its feathers. Sort of like the way you might work conditioner into your hair.

Bird Sound Types and Qualities Part I

Since it’s often hard to see a bird, veteran birders characterize the sounds of birds in order to identify them. So what words do they use? Well, they use “whistle,” for example, to describe the sound of this Olive-sided Flycatcher. And "rattle" for that of the Belted Kingfisher. There's the trill of a Dark-eyed Junco. And the House Wren's “cascade!" The song of a Downy Woodpecker is a sort of “whinny." Listen again and see if you can recognize the types of sounds.

An Inclusive Approach to Bird-a-Thon
00:01:45

Bird-a-thon is Massachusetts Audubon’s biggest fundraiser. Teams of birders spend 24 hours competing to observe as many bird species as they can, to encourage people to donate. But Meghadeepa Maity, who helped organize Bird-a-thon in 2021, realized that not everyone can spend all day traveling to find birds. They started to think of other approaches. Meghadeepa, who’s also an organizer for Birdability, helped create an inclusive Bird-a-thon experience: a stationary count circle at a wildlife sanctuary. The event had a great turnout — and plenty of birds.

Team Nuthatch competed in the 2022 World Series of Birding. The team was organized by Birdability, a group that promotes accessibility in birding, and consisted of people with different disabilities. Despite challenging weather, the team persevered and won an award in the competition. Team member Jerry Berrier says that the team had to work together to find wheelchair accessible locations and quiet space for those with sensory concerns. And the group bonded quickly, like when Jerry volunteered to teach a teammate how to guide a person who is blind.

Ravens and Crows - Who's Who?
00:01:45

Is that big black bird a crow or a raven? How can you tell? Ravens (seen right here) often travel in pairs, while crows (left) are seen in larger groups. Also, study the tail as the bird flies overhead. A crow's tail is shaped like a fan, while the raven's tail appears wedge-shaped or triangular. Another clue is to listen closely to the birds' calls. Crows give a cawing sound, but ravens produce a lower croaking sound.

00:01:36

Smaller than a pigeon — but fierce enough to knock one from the air — are the powerful, compact falcons known as Merlins. Climate change is pushing ranges of many birds farther north, but more and more Merlins have been nesting farther south, in towns and cities across the northern United States. Merlins will take over old crow nests, especially in conifer trees, in parks, cemeteries, and neighborhoods.

In the center of Oakland, California, is Lake Merritt. People row in it, picnic and jog around it, and it's a place of respite within the city. And it hosts waterbirds such as ducks, geese, egrets, pelicans, cormorants, and coots. A beautifully illustrated field guide by Alex Harris, The Birds of Lake Merritt, describes the birds found around the waters of Lake Merritt, its history since the Ohlone peoples have populated it, all the way till today.

Listening in on Birds
00:01:45

Collecting data on wild birds is crucial for their conservation. But it requires huge amounts of effort. One way to help streamline the process is with gizmos called autonomous recording units, or ARUs. For days or months, these recording devices eavesdrop on the environment around them, including the songs and calls of the local birds. Identifying the songs picked up on recordings can be almost as time-consuming as in-person field work, but new AI tools are quickly making it easier to analyze the audio.

Ancient Murrelet Migration
00:01:41

We're used to birds migrating north to south and south to north. But the Ancient Murrelet migrates east to west and back across the North Pacific. These plump seabirds nest in colonies in old-growth forests, in burrows and rock crevices. But where do they go in winter? After breeding, many Ancient Murrelets migrate westward. Around November, they end up in the Yellow Sea or the Sea of Japan. Two months after that, they head back, reaching British Columbia in March, and the cycle begins anew.

In the Departamento de Maldonado of Uruguay, lives a biologist, Nicolás Marchand, who has been working with ranchers to make conservation and sustainability compatible with raising cattle in grasslands. A kind of approach that makes sure pastures for livestock also help host birds like the Buff-breasted Sandpiper, which spend their winters here. He wants to keep enhancing connections with ranchers, restoring pastures, and creating management practices that benefit wintering shorebirds — all to avoid losing more of these crucial ecosystems.

To help backyard birds through the winter, do less. Leave the leaves or rake them under plantings. The tasty insects and spiders underneath will be food for the towhee and this Song Sparrow. Don’t deadhead. Pine Siskins and goldfinches love to snack on dead flowerheads. Make an insect hotel out of natural objects, flower pots, or other “found” items to create hidey holes for insects. They will become food for wrens and other birds.

Acorn Woodpecker Granaries
00:01:38

The Acorn Woodpecker is found in parts of the western US. It chips small recesses out of trees to fit the acorns it will harvest throughout the fall. A family of Acorn Woodpeckers may use this storage tree, or granary, for generations. Some of them hold as many as 50,000 acorns. So does the Acorn Woodpecker just kick back and munch acorns all winter? Nope! In the weeks after a fresh acorn is lodged in a hole, it dries and shrinks. So Acorn Woodpeckers spend much of the winter shuttling acorns from one hole to another, finding just the right fit.

Some ducks don't sound like ducks at all. Some, like the Harlequin, squeak. Harlequins are unique in other ways, too.

If you're lucky enough to spot a Harlequin Duck, you may guess how it got its name. Dressed in vivid multi-colored patches, Harlequin is the jester of traditional Italian comedy.

The Green Heron forages on the banks of small bodies of fresh water. Relying on its plumage for camouflage, it perches motionless — body horizontal and stretched forward — waiting for small fish to come close. This heron may use "bait" while hunting for fish. It drops a feather, a live insect, or a twig on the water's surface. Then it hunkers down and waits for unsuspecting prey to venture within reach. Clever heron!

The White-vented Storm-Petrel is a small black and white seabird found off the coasts of Chile and Peru. Storm-petrels spend their entire lives at sea, except when nesting. Scientists had long been mystified about just where this species nests. A search lasting eight years led them to a site 50 miles inland in the Atacama desert, a place often compared to the surface of Mars. They employed dogs specially trained to sniff out seabirds. The dogs helped locate White-vented Storm-Petrel nests tucked into mineral deposits deep in the desert.

Recent research has demonstrated that birds with access to salmon have higher survival rates. And they are 20 times more likely to attempt to raise two broods in a season, the most important contributor to population growth.

The feathers of a bird are, for their weight, among the strongest structures in the world. The bones of this Magnificent Frigatebird weigh less than its feathers! To further reduce weight while maintaining strength, many bird bones are fused. In addition, the pectoral and pelvic girdles and ribs are joined to make a rigid box that supports those long wings, just as the wings support the bird.

The Bird of Freedom

There’s a bird in Cuba with plumage in blue, red and white — the same colors as the nation’s flag. The Tocororo, or Cuban Trogon, is the national bird of Cuba. When the Tocororo is kept in a cage, they often die. This fact has become a metaphor of freedom embraced by Cubans. The Cuban Trogon is a medium-sized bird often found in pairs. Its song sounds like its Spanish name, “Tocororo.” While el Tocororo is currently abundant, its population is declining due to loss of habitat.

The White-throated Sparrow’s melancholy whistle is hauntingly beautiful. But when you hear an adult sparrow performing, just know that the bird wasn’t always an expert singer. In the fall, listen for White-throated Sparrows rehearsing their song. Inexperienced young birds sometimes begin with disorganized jumbles of notes known as sub-songs. As winter deepens, the first-year birds begin to get the syllables of their songs down, but they might sound shaky and off-key. But by summer, hopefully, all the new adult birds will be virtuosos.

The cheerful-voiced Chestnut-collared Longspur shares its northern prairie breeding range with grazing cattle. Although heavy grazing can have adverse effects, breeding densities of longspurs jump by two, three, or even 10 times when ranchers graze their cattle responsibly on native prairies. Two centuries ago, the birds were probably more abundant on prairies used by bison than on untouched stands of tall grass.

One such species is the Western Sandpiper, here known as el playerito occidental, wants to eat. But wetland habitats where they find their food are affected by the shrimp farming industry. Juanita Fonseca works with the Western Hemisphere Shorebird Reserve Network and with Manomet, creating guidelines that help shrimp farmers share the coastline with shorebirds.

The Feminist Bird Club
00:01:45

The Feminist Bird Club, or FBC for short, is a birding group that’s intentional about making sure people from all backgrounds feel welcome, says FBC board member Jeana Fucello. At this group’s events, birding and social justice go hand-in-hand, says Kasia Chmielinski, the co-founder of the Jersey City FBC chapter. The group discusses the history of the place they’re visiting, from the original inhabitants of the land to the legacies of polluting companies — helping contextualize the place and its wildlife.

An Albatross Surfs the Wind
00:01:27

By moving from the faster high air to slower low air, or vice versa, an albatross can propel itself forward. In a series of sinuous loops, the albatross surfs the wind, up and down, repeating the pattern over and over again as it moves thousands of miles across the ocean.

Why Are There Flightless Birds?
00:01:45

The ability to fly seems to define birds. But there are more than 50 species of flightless birds throughout the world — from the Ostrich and Kiwi to flightless rails, ducks, and this Humboldt Penguin. Why did they evolve the inability to fly? Many dwelt on islands. Others evolved until they were huge -- like the extinct 12-foot-tall Moas of New Zealand. And the penguins? Unlike most flightless birds, they still have the strong flight muscles and keeled breastbones of flying birds. They are supremely graceful flyers. But they do it under water.

 In this episode of BirdNoir, the P.I. gets a call from someone desperate over a bird stealing a tuft of her precious Pomeranian’s fur. The detective is able to ID the thief, a bird with so light a touch that it can take fur from a snoozing dog without waking it. The motive: nice, warm lining for the bird’s nest.

Putting the Hum in Hummingbird
00:01:45

To figure out the source of a hummingbird’s hum, scientists built a special rig to measure air pressure, twelve high-speed cameras, and over 2000 microphones to observe hummingbirds fluttering in place at an artificial flower. The researchers found that the hum derives from the difference in air pressure between the top and bottom of the wings, which alternates forty times a second as the hummingbird flaps. The rapidly shifting air pressure produces a harmonic set of sounds, from low to high, creating that iconic, musical hum.

Connecticut Warbler
00:01:41

Connecticut Warblers nest in the northern boreal forests, migrate through the Midwest, and winter in the rainforests of South America. Even with all that traveling, you rarely see one of these birds. Though their loud, ringing song might be easy to identify, it often seems to emanate from low in a tree when the warbler is perched high in the crown, frustrating birders from Canada to Brazil.

Inspired by A Lake and a Sister
00:01:45

Marina Castellino and her sister Marcela share a love of birds, especially those living in Mar Chiquita, one of South America’s largest wetlands. Marina got inspired from seeing her older sister’s love for shorebirds. The two sisters helped get Mar Chiquita declared a National Park and National Reserve for Argentina. That supports birds like sandpipers that migrate between South and North America. So if you see one near you, efforts from Marina may have helped you see it there!

Nuthatches Sweeping the Nest
00:01:27

White-breasted Nuthatches aren’t the toughest birds on the block — but when it comes to their nests, they know how to put up defenses. Squirrels could easily duck inside a nest cavity and gobble up the eggs. That’s why you might see nuthatches sweeping around their nest hole with a beetle or other insect. It’s thought that chemical compounds from the insect smell bad to squirrels, driving them away. And if that doesn’t work, nuthatches try to make themselves look as big as possible.

All Those Fish in a Puffin's Beak
00:01:45

Puffins fly under water into schools of slender fish, filling their large beaks. Fish are wedged into the gape, the stretchy skin at the beak hinge, but the bill edges still line up neatly. The dangling fish won’t slide out because the puffin’s tongue and roof of the mouth are heavily lined with backward-angled spines. When its beak is full, the adult flies back to its nest and feeds it all to a single chick.

Snail Kite - Bird of the Everglades
00:01:41

When Florida became a state in 1845, the legislature declared the Everglades, America's largest wetland, totally worthless. In 1905, Napoleon Bonaparte Broward was elected governor on a campaign to drain them. So over the years, the slowly flowing "River of Grass" has been replaced by a series of reservoirs with little water movement. The endangered Snail Kite feeds only on the Apple Snail. And neither kites nor snails flourish in places that are permanently under water. Learn more at StateOfTheBirds.org.

Warbler Migration in Ohio with Kenn Kaufman
00:01:45

Every spring in Northwest Ohio, the shores of Lake Erie transform into a birder’s paradise. Birder and author Kenn Kaufman, who lives in this area, says that of the many species that migrate through here, one group of vibrant, vivacious songbirds stands out from the rest: warblers. Trees leaf out later in the season along the lakeshore, making the tiny warblers easier to see as they forage for food. Northwest Ohio has earned a reputation as the Warbler Capital of the World among birders in the know. But Kenn wishes everyone could glimpse the beauty of warbler migration, even if they don’t make it to the Warbler Capital.

Catching Kori Bustards for Science
00:01:45

In the animal world, large, charismatic species tend to get the most attention. But for the Kori Bustard, the largest flying bird in Africa, that attention hasn't translated to a ton of scientific research. Katherine Mertes, a research ecologist at the Smithsonian Conservation Biology Institute, tracks animals for a living, and a few years ago she was focused on Kori Bustards. Her team used solar-powered tracking devices to study the bustards’ movements. But first, they had to catch the birds — and trying to gently herd a bustard into a giant net is quite a task.

Birds Can Eat Toxic Berries
00:01:45

Many bird species can eat the fruits of plants that are toxic to humans —even the white berries found on poison ivy. These birds just aren’t sensitive to the compounds in the berries that are irritating or poisonous to people. While you probably want to stay away from poison ivy, you can improve habitats for birds by planting native fruit bushes and advocating for wildlife-friendly gardening in public green spaces.

Marcela Castellino works as a conservation specialist for Manomet’s Flyways team, visiting wetlands, salt lagoons, and salt flats around Mar Chiquita in Argentina, one of South America’s biggest salty wetlands. She surveys shorebirds to track their populations and strengthen their conservation. One species she studies, Wilson’s Phalarope, travels from their breeding grounds in North America to winter in huge numbers at Mar Chiquita. As they feed, they swim in circles, swirling the water and stirring up things to eat.

A Bird Migrates South, Step by Step
00:01:42

Wood Thrushes migrate more than 2,000 miles each way, between their summer breeding territories in the US and Canada to where they winter in Central America. During migration, the birds will fly for hundreds of miles at night, then stop for days or weeks to refuel. In the spring, they’ll head north three times as fast as they did during their southbound fall migration.

The Fine Art of Dabbling
00:01:32

Picture this Gadwall duckling swimming slowly across a pond, skimming the water’s surface with its broad, spatulate bill. This behavior is called dabbling. Along with the pond water, multitudes of tiny particles pass through the duck’s bill. Somehow it sorts out and swallows the edible seeds and invertebrates, while rejecting the tiny, inedible bits of grit, mud, and debris. To see how a duck pulls this off, we need to pry its bill open and look carefully inside.

Jaegers Give Chase in September
00:01:45

A tern or gull plunges headfirst into the water, then bounces aloft grasping a small fish in its bill. But before the bird can swallow its catch, a Parasitic Jaeger swoops in. The jaeger nips the bird's wing, and it drops its hard-won fish. The pirate catches the fish in mid-air and gulps it down. The jaeger (German for hunter) is built for sprinting speed and predatory feats.

Bald Eagles Fledge
00:01:37

When young Bald Eagles fledge, the event is the culmination of nearly a year’s work by the parents. Let’s recap how it might have gone: male and female build a nest over the winter. By March, they have two eggs. The female incubates the eggs for about a month, with the male taking an occasional turn. The result? A couple of tiny, three-ounce chicks. At eight weeks, they’re as heavy as the adults — 10 to 14 pounds. Two weeks later, they make their first flights. But it will take another 10 weeks of practice flights and provisioning by the adults before the young birds are ready to strike out on their own.

Banding Birds
00:01:45

Willistown Conservation Trust in Pennsylvania carries out bird banding to help researchers understand bird populations. Led by licensed bird banders, a team of volunteers catches birds using mist nets — 8-foot tall nets made of fine nylon string that practically disappear when strung out between poles. After carefully untangling birds from the net, volunteers weigh and measure the birds, affixing a small metal band to their legs with a unique ID. Compiling records for many banded birds helps keep track of whole species.

Including Female Birds in Conservation Plans
00:01:45

For many species of birds, scientists know more about the males than the females. And that’s a problem when making a conservation plan for a species that maps out which habitats to protect. Joanna Wu, a PhD student at UCLA, says that in some species of warblers, males and females live in completely different habitats during the winter. Joanna hopes to study how to better incorporate female birds into conservation efforts and ensure that the whole species is protected.

By late summer, the male Mallard’s need for fancy feathers to attract the females has passed. These birds have molted, and their bright feathers are replaced with mottled brown ones. Subdued colors help camouflage the male ducks, protecting them from predators. Come fall, the male Mallards will molt again and become the colorful dandies we remember.

Owls Migrate, Too
00:01:45

When you think of bird migrations, you might think of a bluebird or a robin first. But some owls do migrate – such as the Short-eared Owl, which flies south for the winter. Northern Saw-whet Owls were once thought non-migratory, but in fact they travel at night, unseen. Snowy Owls breed in the Arctic then wander toward the south, staying wherever they can find food. Some Burrowing Owls spend their whole life in one place. But others migrate every spring and fall with the regularity of a bluebird.

Jays Identify Good Nuts by Shaking Them
00:01:38

Some birds stash unopened seeds for use later. But how do they know which seeds are worth the trouble, before expending the energy to open them? A team of scientists from South Korea and Poland may have an answer. As part of a series of experiments, the scientists observed the behavior of Mexican Jays presented with peanuts in their shells. The research team documented the birds shaking nuts in their beaks to assess the weight and possibly listening for the nuts rattling. In other words, jays use the same types of sensory cues that humans do when choosing a melon in the supermarket.

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and cinnamon belly, and chase down swifts, dragonflies, and the bats that give them their name. Ornate Hawk-Eagles stand over two feet tall and are capable of catching monkeys.

August Molt
00:01:45

By August, many birds have just completed the intense rigors of nesting and raising young and now undergo a complete molt. Molt is a cyclic process of feather growth. As new feathers grow in, they push the old ones out. Why molt? Because feathers wear out. Songbirds that migrate long distances need to complete this process on a tight schedule, to be ready when it's time to strike out in September. You might not even recognize this American Goldfinch in its winter plumage.

Protecting Petrels that Live on a Volcano
00:01:45

The ‘Ua’u or Hawaiian Petrel is an endangered species once thought extinct or nearly so. But in recent decades, biologists have relocated some of their well-hidden nests — such as underneath the lava fields of Mauna Loa, an active volcano. Areas where the lava has long since cooled have deep tubes in which the ‘Ua’u can make their burrows. Despite their secretive burrows, the ‘Ua’u are still at risk of predators such as feral cats. A fence completed in 2016 keeps predators away from the petrel burrows, giving them a space to thrive.

Lights Out for Bird Migration
00:01:38

Many birds migrate at night, taking advantage of less turbulent conditions and cooler temperatures. But that also means that migrating birds  can get disoriented by bright lights and collide with a building. Julia Wang is the project leader for BirdCast, which provides forecasts for bird migration so that people know when they should keep their lights off. Turning off the lights during peak migration times can save birds and save energy at the same time.

Public radio station WYSO in Yellow Springs, Ohio, renovated a historic schoolhouse to move into. But there was a bird problem: the old chimney had to come down, and Chimney Swifts were known to nest in it. So the station decided to custom-build the swifts a new home: a Chimney Swift tower right on the front lawn. The builders worked quickly to finish the tower ahead of the Chimney Swift’s spring migration, and WYSO staff members played recordings of swift calls to help attract them to the new home.

The ‘Alalā is a crow species that only lives on Hawai’i. In the 1990s, the species was on the verge of extinction. So biologists decided to raise ‘Alalā in captivity, aiming to release them once the captive population was big enough. But these intelligent birds have to learn many skills to survive in the wild, such as communication skills and avoiding predators. Several ‘Alalā were released and seemed to get the hang of avoiding hawks. These experienced birds returned to captivity and could help pass on their knowledge to the next generation.

How Birds Stay Cool
00:01:45

On a hot summer’s day, watch a bird such as a crow — or this Purple Martin — very carefully. You’ll never see them sweat, because birds don’t have sweat glands. So how do they keep cool? One way is panting. As the bird breathes rapidly, heat is carried out of its body through the lungs and air sacs. Bare skin on the legs, face, and beak also help with cooling. So do puffing out feathers, fluttering wings, or splashing in a puddle or birdbath. And soaring birds like hawks can simply ride the updrafts far above ground to cooler air.

Saving Honeycreepers from Avian Malaria

Avian malaria has devastated native Hawaiian birds called honeycreepers. And now, climate change is allowing the mosquitoes that carry the disease to spread into the last mountain refuges of highly endangered honeycreepers on the island of Kauai. However, there’s hope that a new tool could eradicate the disease. Researchers are raising mosquitoes in the lab infected with Wolbachia, a bacterium that makes them infertile. When these males mate with wild female mosquitos, they fail to reproduce. While they wait for the mosquito solution to become available, biologists are carrying out last-ditch efforts to keep the species alive in captivity.
