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
Bald Eagles' Daredevil Cartwheel Flight
00:01:34

Two eagles locking talons high above the ground might look like they’re risking injury, but it’s a normal courtship behavior called the “cartwheel display.” Fully entangled, the two birds begin spinning to the earth, disengaging just before they smack the ground. Their clasp could last for hours. At last, the eagles unlock talons and fly off. Rival adults sometimes perform the same flight. Learn more at BirdNote.org.

Pterodactyls and Birds
00:01:39

Pterosaurs—the giant, leathery flying creatures of the age of the dinosaurs—were giant reptiles, NOT dinosaurs. The pterosaurs had slim bodies and thin-walled, lightweight bones, ideal for flying. They thrived for 160 million years, passing into history after the same asteroid strike that finished off the large dinosaurs. Today’s birds are modern-day dinosaurs, descended from creatures similar to the terrifying T-Rex. Learn more at BirdNote.org.

Bringing Birds to the BeltLine
00:01:46

We tend to favor clean-cut lawns and non-native plants, but that’s a real problem for our ecosystems and the birds that live in them. Tenijah Hamilton, the host of Bring Birds Back podcast, joins volunteers planting native flowers and grasses on the Atlanta BeltLine, a converted “Rail Trail”. Trees Atlanta Co-Executive Director Greg Levine explains how native plants can reconnect wild animals to urban areas. Learn more at BirdNote.org.

July before Dawn - Aldo Leopold
00:01:46

The song of this Field Sparrow was the first bird song Aldo Leopold awoke to on his Wisconsin farm in the 1940s. Sadly, Field Sparrow populations are declining rapidly. You can learn more about "The State of the Birds" from National Audubon, and the plight of the Field Sparrow in particular. Learn more at BirdNote.org.

Vulturine Guineafowl
00:01:42

The Vulturine Guineafowl is a striking bird. It lacks feathers on its head and neck and has a blue breast with silvery plumes. The species has a complex social structure. Distinct groups, similar to high school cliques, mingle but don’t change membership. Such a multilevel society was previously only known in large-brained mammals such as primates, dolphins, and elephants. Learn more at BirdNote.org.

Birds' Early Warning Systems
00:01:29

A frantic cacophony of loud, rapid birdcalls tells other birds there’s a predator on the prowl. It’s called “mobbing” as birds clamor and dart — back and forth — at the threat. An ongoing study of mobbing and other bird warning behavior suggests that some birds listen in on the warnings of other birds. A wave of warning calls spreads from one hillside to another at more than 100 miles per hour. So vulnerable birds may be clued in to the movements of predators like this Northern Pygmy-Owl, giving them time to take cover. Learn more at BirdNote.org.

Barn Owls Let You Know
00:01:46

The structure and delicate softness of its feathers allow a Barn Owl to approach its prey almost without sound. The Barn Owl's ability to locate prey by sound, even when concealed by snow or leaves, is the most precise of any animal yet tested. This young Barn Owlet is about five weeks old and actually weighs more than its parents. During and after the fledging period, it will gradually lose weight, as it learns to hunt for itself. Be sure to watch the video of an owl hunting. Learn more at BirdNote.org.

A Different Drumming
00:01:43

The drumming of the male Ruffed Grouse is one of the most evocative sounds of the North American forest. Familiar as these accelerating burps are to hunters and hikers, the origin of this bizarre sound was long a mystery. It took the advent of wildlife cinematography to solve the riddle. In the spring of 1929, Cornell University’s Arthur A. Allen filmed a drumming Ruffed Grouse. Frame-by-frame analysis showed the bird’s wings were striking nothing but air — hard and fast enough to produce popping sounds that ran together into the whirring drum. Learn more at BirdNote.org.

Birds on the Polar Bears’ Menu
00:01:46

Polar bears use Arctic sea ice to hunt seals, but a warming Arctic means the bears have to return to land earlier in the year. Their arrival coincides with droves of birds sitting on eggs. A single clutch of eggs isn’t enough to satisfy a bear, so they go from nest to nest, sometimes eating their way through a colony. Scientists designed a bear-proof nest case to protect Black Guillemot eggs. Learn more at BirdNote.org.

American Robin Babies Afoot
00:01:39

After hatching, baby robins spend up to 15 days in the nest. By July, many young American Robins have left the nest, or fledged. But they aren't ready to make it entirely on their own yet, and they follow their parents around, learning to fend for themselves. Outside of the breeding season, robins tend to form large flocks, often feeding on berries and fruits. Learn more at BirdNote.org.

The Tui of New Zealand
00:01:46

The Tui is one of New Zealand’s most remarkable birds, intelligent and with iridescent feathers. Its down-curved beak fits perfectly into native flowers. But the Tui is best known for its voice. Each Tui’s complex song is slightly different, a colorful mix of musical notes and offbeat sounds. It’s one of the few birds that can imitate human speech — and even accents.

Who Was That Masked Bird?
00:01:41

Football and baseball players sometimes wear eye black to reduce glare from the sun or stadium lights. According to scientists, some birds — including many shrikes, like this Northern Shrike — have evolved a band of black feathers across their eyes that helps in the same way. The black markings may also help the birds hunt and fool predators. Learn more at BirdNote.org.

Birds in Summer - The Heat of the Day
00:01:41

Just a few weeks past the solstice, and the real heat of summer is yet to come. Some shorebirds are already on their way south, but most songbirds will be here for a while longer. What's the best time of day to look for them? Many birds are most active in the early morning, taking advantage of the abundance of insects at that hour. Midday heat sends people inside, and birds take a siesta, too. And then, both birds and bugs rev up again in the late afternoon. But hummingbirds and also gulls — including this Glaucous-winged Gull — forage all day long! Learn more at BirdNote.org.

Towhees' Distractive Plumage
00:01:37

Both this Eastern Towhee and the Spotted Towhee of the West sport a black or dark brown hood and back. And when they fly, their tails flash white. When a hawk gives chase, the towhee's flashing tail-feathers draw the predator's attention. Momentarily distracted, the hawk may come up with just a couple of tail feathers — as the towhee escapes into the underbrush. So if you see a towhee missing a couple of tail feathers, it may be that the flash of white — the distractive plumage — saved its life. Learn more at BirdNote.org.

What Makes an Efficient Flying Bird?
00:01:46

Every bird species uses its wings a little differently, and some are specialized for highly efficient flight. But that means going without other abilities. Swallows and hummingbirds capture their food on the wing, but they can’t walk. Swifts, which are acrobatic in the air, can’t even perch. Yet they dazzle with the maneuverability made possible by their aerodynamic bodies. Learn more at BirdNote.org.

Jul 16, 2021
Loggerhead Shrike
00:01:42

Loggerhead Shrikes are found across much of the United States in open country, like pasture and sagebrush. Male shrikes are well known for impaling their prey on thorns, creating a larder that may help impress potential mates. But pesticides and the loss of habitat to residential and commercial uses have reduced shrike populations. Conservation efforts are under way, such as allowing brush to grow along fence-lines, leaving small trees and shrubs on the roadside, and reducing or eliminating the use of pesticides.

Giving Your Cat a Great Life Indoors
00:01:46

Outdoor cats kill billions of birds each year in North America — and they live much shorter lives than indoor cats. But life as an indoor cat doesn’t have to be boring. On Bring Birds Back podcast, cat behaviorist Jackson Galaxy discusses how just 15 minutes of creative play with your cat can make a huge difference. Plus, letting cats watch birds through the window can act as “Cat TV.” Learn more at BirdNote.org.

A Fascination with Cranes, With George Archibald
00:01:42

George Archibald has devoted his life to the conservation of cranes, including the Whooping Crane pictured here. His inspiration? At the age of eight, George heard a radio broadcast about Whooping Cranes at school. He says, “. . . it was this drama of a male and female crane who’d flown the gauntlet to get 2,700 miles from Texas to their breeding ground . . . I never forgot it!” Learn more at BirdNote.org.

Play and Brain Size
00:01:46

Many birds that play do it alone by swinging, sliding, or rolling around. Some species interact with objects, like dropping a stone and picking it up again. But a select few birds – like these crows – play with other members of their species. Scientists call this social play. It appears to have implications for the evolution of brain size among birds as well as our own species. Learn more at BirdNote.org.

Puffins - Clowns of the Sea
00:01:40

Puffins are icons of the seabird world. With clown-like faces and huge, multicolored bills, they stand upright on sea cliffs along the northern oceans. Tufted Puffins nest on islands and rough coastlines, from the Channel Islands of Southern California across the north Pacific to Siberia. The Atlantic Puffin, like this one, breeds in the North Atlantic. Be sure to watch a video by Project Puffin, off the coast of Maine. Learn more at BirdNote.org.

Okefenokee Swamp and Prothonotary Warbler
00:01:46

The Okefenokee National Wildlife Refuge was set aside to protect the fabled Okefenokee Swamp of Georgia and Florida. Tall cypress trees and Spanish moss give the swamp a prehistoric appearance. The Prothonotary Warbler is one of the most striking of the swamp’s denizens. Having wintered in the West Indies, a male might return to the Okefenokee and establish a breeding territory. Because it lives down in the realm of trunks and branches rather than up in the leaves, the Prothonotary has adopted an unusual nesting habit for a warbler: it nests in natural crevices or old Downy Woodpecker holes!

Murres' Swimming Migration - With Bob Boekelheide
00:01:44

When we think of avian migration, we generally think of birds in flight. But Common Murres migrate north by swimming. Some Pacific Coast murres paddle north to the sheltered bays of the Strait of Juan de Fuca to feed on herring and other small fish. During their ocean migration, the adult male murres molt their flight feathers and — like the chicks they shepherd — cannot fly. Heading north, they live on the sea. Imagine! A journey that spans two months and may cover hundreds of miles. Learn more at BirdNote.org.

The Ferocious Feet of the Great Horned Owl
00:01:46

Great Horned Owls excel at nocturnal hunting, thanks to their acute senses and stealth — but their feet let them secure squirming prey. The outermost of their four toes can rotate forward or backward, an advantage that most other birds of prey lack, letting them capture animals as large as raccoons. A four-pound owl can take flight with six pounds of prey. Learn more at BirdNote.org.

Peatlands - Maine's Sunkhaze Meadows Refuge
00:01:46

The habitats that comprise Sunkhaze Meadows Refuge in central Maine — including peat bogs, streamside meadows, shrub thickets, cedar swamps, and maple forests — are rich with bird life, like this Yellow-bellied Flycatcher. You’ll also find Bobolinks and more than 20 kinds of warblers during the summer months. The flycatchers return to Sunkhaze Meadows annually from Panama, while Bobolinks migrate to Maine from as far as Bolivia. Learn more at BirdNote.org.

Dove or Pigeon?
00:01:42

The word “dove” might make you think of an elegant bird symbolizing peace, while the word “pigeon” might bring up images of rowdy flocks of city birds. But there’s no formal distinction between doves and pigeons, only a linguistic one. In many languages, the birds are one and the same. The dove and pigeon family includes some of the most beautiful birds in the world. Learn more at BirdNote.org.

Green Jays and Santa Ana National Wildlife Refuge
00:01:32

Bird life is abundant on the Santa Ana National Wildlife Refuge in southern Texas. This large stretch of Tamaulipan brushland was preserved for its wildlife, including many species found nowhere else in the United States. One of the special birds on this refuge is the Green Jay. These jays and other birds persist in Texas because of active conservation of habitat along the Rio Grande. A series of refuges there -- Santa Ana, the World Birding Center, and others -- provides a wildlife corridor that allows birds and other animals to move up and down the river, assuring their survival in the midst of farmland.

Manakins Make Their Own Fireworks
00:01:46

The White-bearded Manakin lives in Trinidad and throughout much of South America. The males court females by snapping their wings with firecracker-like pops. A flurry of males flits rapidly back and forth from one slender, bare sapling to another, a foot above the ground. When the male spots the female nearby, he slides down an upright twig, his head held downward, wings whirling, white chin-feathers thrust out like a beard. Learn more at BirdNote.org.

David Sibley - Sketching and Painting Impressions
00:01:31

David Sibley’s paintings connect millions of people with the lives of birds. His talent in observing and portraying birds culminated in The Sibley Guide to Birds. Sibley describes how he learned to sketch and illustrate birds such as this Townsend’s Warbler: “I spent years in the field, just traveling and birding and sketching,” he says. “ . . . The drawing was so important to me, that there was never any question in my mind of continuing to paint the birds. It’s how I study the birds.” Learn more at BirdNote .org.

Experience Wildness with Adrian Dorst
00:01:46

In a wild place on the west coast of Vancouver Island, author, photographer, and birdwatcher, Adrian Dorst, tells of a time he witnessed fifty or sixty thousand migrating Western Sandpipers: “It looked like snow – except that the snow was drifting upwards! It was just an amazing sight – so many birds in the air. I mean it’s quite overwhelming to try to estimate, when there are so many birds in the air at once. But based on doing bird counts here for so many years, that’s the figure that we came up with ... fifty or sixty thousand. Quite a sight!” Learn more at BirdNote.org.

Birdsong on the Talus
00:01:45

The ringing notes of a Rock Wren’s song reverberate across a steep, rocky slope in the American West. The Rock Wren is most at home in piles of rock rubble at the foot of cliffs, a life zone known as a talus slope. These wrens find shelter, safe nesting, and a good supply of insects in the crevices among the talus. They often share the slope with birds such as Say’s Phoebe and the sweet singing Canyon Wren. Venture high enough in the western mountains, above tree level into the alpine zone, and you’ll find talus slopes interspersed with bits of low tundra – home to one of the continent’s most reclusive birds, the White-tailed Ptarmigan.

Catios - The Best of Both Worlds
00:02:37

Cats love the outdoors, but they’re also one of the biggest threats to birds — killing as many as four billion a year in North America. Outdoor cats also live much shorter lives. Cynthia Chomos designed a cat patio or “catio” so that everyone can win. The enclosed outdoor space keeps both cats and birds safe.

Blackbirds' Strange Music
00:01:34

Blackbird songs have a strange music. The Red-winged Blackbird can be heard in nearly every marsh on the continent — bold, brassy, and piercing. The songs may not seem musical, but they definitely get your attention. Brewer’s Blackbirds, which live in open habitats like farms and grasslands, make a wet, slap-in-the-face sound. The combined voices of Tricolored Blackbirds — like this one in a California marsh — sound like a snarling catfight. Another Western bird, the Yellow-headed Blackbird, makes raucous growls, wails, and whistles. Learn more at BirdNote.org.

Greater Ani
00:01:46

Greater Anis make communal nests in which two or more pairs share responsibilities. But that doesn’t mean they cooperate with their neighbors. Researchers in Panama captured anis on camera tossing fake eggs out of artificial nests. Although scientists haven’t yet seen anis destroy real nests, the evidence suggests that anis engage in neighborhood disputes. Learn more at BirdNote.org.

The New Jersey Pine Barrens
00:01:42

In southern New Jersey lies a region known as the Pine Barrens, home to many birds, including this Great Crested Flycatcher. With broad tracts of pine forest interspersed with grassland and shrubland, the Pine Barrens remain one of the largest expanses of green in the Northeast, supporting a diversity of plants and animals. Early European settlers tried farming here, but the sandy, acidic soil wasn’t suited to their traditional crops. Upland Sandpipers and Prairie Warblers nest here. Agricultural barrenness has saved the Pine Barrens and its native habitats. If its soils grew traditional crops, it would have – centuries ago – disappeared beneath the plow.

Three Buntings - Indigo, Lazuli, and Painted
00:01:46

Each spring and summer, Indigo Buntings sing their buzzy, jumbled songs from brushy edges throughout the Eastern US. West of the Rockies, a different bunting sings his song. Named for the gemstone lapis lazuli, a male Lazuli Bunting shimmers an iridescent azure. He looks as if he might have been fashioned by a maker of Navajo jewelry. Yet another bunting sings atop thickets and shrubs in the Southeast and south-central US – the Painted Bunting, perhaps one of the most colorful birds in all of North America. Enjoy the bunting singing in your neck of the woods this summer, for this fall, they’ll all be gone to the tropics until next spring. Learn more at BirdNote.org.

Common Murres - Nature's Laugh Track
00:01:40

The raucous laughter of the Common Murre rings out from a nesting colony, high on a narrow ledge on a sea cliff. Precarious as their nest site is, Common Murres nest by the thousands along the Pacific Coast, perhaps millions north along the Bering Sea. Their eggs are pointed at one end and blunt at the other, so they spin on the ledge rather than tumbling into the sea. Common Murres stand nearly a foot and a half tall. With legs set far back on their bodies, they look much like the northwestern equivalent of penguins of the Southern Hemisphere. Learn more at BirdNote.org.

House Wren - Little Brown Dynamo
00:01:46

House Wrens dart from perch to perch and sing almost nonstop. They’re one of the most thoroughly studied songbird species. House Wrens nest in cavities, including backyard nest boxes. Most migrate south in late summer. The male House Wren sometimes builds multiple nests, allowing his mate to choose her favorite and put her finishing touches on it. Learn more at BirdNote.org.

Urban Cooper's Hawks
00:01:42

Next time you’re in the city, look up. When pigeons are wheeling, you might just see a different bird in pursuit. The Cooper’s Hawk, once known as the “chicken hawk,” used to be in steep decline due to hunting and the effects of DDT on breeding. Today, it’s the most abundant of the bird-eating raptors over much of North America, living even in the city. Males are smaller and often prey on Mourning Doves and other easy pickings at city parks. The bulkier females hunt pigeons, adding a dash of wildness and drama to the modern cityscape — in the form of pigeon feathers falling silently from the sky. Learn more at BirdNote.org.

Spark Bird: Kaeli Swift and the Rooftop Crows
00:02:31

When Dr. Kaeli Swift was in college, she became obsessed with the Corvid family of birds, which includes crows, ravens and jays. She decided to study whether crows learn to recognize certain human faces as friendly. She tried putting a mask on a mannequin holding peanuts, but the crows spotted the trick right away. Swift had to find a creative solution. Learn more at BirdNote.org.

The Value of a Dust Bath
00:01:33

It might sound strange, but dirt helps birds scrub themselves clean. Birds of all sizes (like the Eurasian Skylark seen here) often scrape a depression in the ground and flick dirt onto their bodies, shimmying to shake it off. Experiments showed that birds use dust to prevent oils from building up

How Nestlings Leave the Nest
00:01:46

Young birds leave their nests in different ways. Some shuffle tentatively along the nearest branch and practice flapping their wings, while others take the "big leap." Which path they take depends upon their species and the location of the nest. Young Great Horned Owls clamber out of the nest to

Robins Are Very Choosy Nesters
00:01:42

When scientists looked at climate data for more than 8,500 robins’ nests in the US, they found that robins will nest only if the mean noon temperature is between 45 and 65 degrees. But even more critical is relative humidity: it needs to be around 50 percent in the middle of the day. What’s so

Choosing Where to Nest
00:01:42

When it comes to building a house, one of the first decisions is where to put it. The same is true for birds. It's called "nest site selection." And one thing most birds have in common? The female chooses the site. A robin builds its nest on top of a stout branch. This Warbling Vireo hangs its nest

Locating a Bird by Sound
00:01:30

To locate where a sound is coming from, we use time lag. A sound coming from the left is first detected by the left ear, then ever-so-slightly later by the right ear. But the ears of some small birds (like these Carolina Wrens) and insects are too close together for them to use time lag alone. So

When a pair of Western Grebes decides it’s time to mate, they call loudly and approach one another. Each bird curves, then straightens, its long neck gracefully. They then face each other, necks on the water’s surface, their bills flipping up drops of water. If attraction prevails, they rush

Tufted Titmouse - What's in a Name?
00:01:43

A Tufted Titmouse has just about everything you could ask for in a backyard bird. Petite and strikingly elegant, it’s as perky as a chickadee. In fact, it’s a cousin to the chickadee. And as it comes boldly to your seed or suet feeders, the Tufted Titmouse will even hang upside down like an acrobat

Ospreys Never Stop Building
00:01:31

Ospreys are remarkable nest builders. Many reuse their massive stick nests from the previous year, but continue tinkering with it once the nesting season begins. And the nest transforms along with the growing chicks. It’s bowl-shaped at first, corralling the young birds, but it gets flatter after

Listen for Tapping
00:01:46

Woodpeckers are our most familiar bird carpenters, but other birds also chip out nests in trees and wood structures. Nuthatches — like this Red-breasted Nuthatch — are exceptional wood carvers, with their chisel-like bills. Chickadees will peck into less dense wood, carrying out wood chips by the

Nesting Niches
00:01:46

American Robins (like this male seen here with its young), House Finches, and Song Sparrows may all nest within one small garden. By selecting different nesting strata, the species avoid competing for the same nesting sites. If you plant your garden in multiple layers – trees both short and tall

Red-Tailed Hawks - Adaptable Diners
00:01:43

Red-tailed Hawks are found year ‘round in a wide variety of natural landscapes, from meadows to forest edges, deserts, and canyons. One big reason we see Red-tailed Hawks in so many places is their remarkable adaptability as hunters. They vary their diet to what is locally abundant. So along the

Unique Chaparral
00:01:46

The dense cover of coastal chaparral supports many birds found nowhere else in the world, including this California Thrasher. The plant species are different, but the chaparral of California is much like shrubby coastal vegetation in southern Europe, South Africa, southern Australia, and Chile. All

The Marsh Wren's Many Nests
00:01:33

Tiny Marsh Wrens live in wetlands, usually within cattails, reeds, or bulrushes. After choosing his territory, the male weaves up to 15 dome-shaped shells, lashing together cattails, grasses, or reeds. These are called "courting" nests. Then, sitting high atop a perch in the marsh, he sings

Flickers and Buffleheads
00:01:46

After a Northern Flicker carves out a nest cavity, chances are the birds will use the cavity for just one nesting season. But the cavity may have a prolonged career as a home for small owls, bluebirds, swallows, and other birds - including the Bufflehead. Buffleheads - like the family seen here -

From Egg-laying to Hatching and Beyond
00:01:39

Waterfowl like this Muscovy duckling spend up to 30 days in the egg, so they’re able to walk, swim, and feed themselves as soon as they hatch. We call these chicks precocial. By contrast, the chicks of most songbirds spend less time maturing in the egg. They must continue to develop in the nest

Three Brown Thrushes
00:01:46

The Swainson's Thrush, the Hermit Thrush, and this Veery are small, brown birds, but their songs clearly distinguish them. The Swainson's Thrush announces its presence in early spring with subtle, limpid "whit" or "wink" sounds. Many rate it among the finest singers. A Veery's phrases tend downward

The Harsh Beauty of Grackle Songs
00:01:42

Ranging from metallic hisses to electronic yodels, sounds of grackles may not be music to our ears—but they have their own rough beauty, a distinctive, primal harshness. Grackle songs evolved to carry through their nesting habitats — dense marshes and brushy landscapes — where more lyrical notes and
