What does the Pacific Wren hear in a song? It's a long story. What we hear as a blur of sound, the bird hears as a precise sequence of sounds, the visual equivalent of seeing a movie as a series of still pictures. That birds can hear the fine structure of song so acutely allows them to convey much information in a short sound. Pacific Wrens are found most often in closed-canopy conifer forests, nesting in cavities, usually within six feet of the ground. More info and transcript at BirdNote.org ....

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 wil...

The Greater Roadrunner is a common species in the desert and brush country of the Southwest, but its full range reaches from California to western Louisiana. Its soft cooing voice hints at its connections to another bird: scientists group roadrunners with the cuckoos. Where to see a roadrunner? In the US Southwest, you might spot one along the roadside, standing atop a boulder. It can reach speeds of nearly 20 miles an hour and can fly — but doesn't very often.

Ornithologist Bill Evans has helped us better understand the sounds that birds make as they migrate at night. Known as nocturnal flight calls, many species can be identified based on their signature sound. Using special handmade microphones left outside overnight, Evans, his colleagues and many volunteers recorded countless nocturnal flight calls — and not all of them have been identified yet. In this show, revel in the beauty of the calls that birds make as they fly high in the air. More info a...

Vampire Ground-Finches menace their victims in broad daylight, stabbing holes in their flesh, then devouring the blood. During the dry season, when their usual diet of seeds can be scarce, they turn to large seabirds, like boobies. Fluttering onto a booby’s back, the finch jabs its sharp beak in among the feathers until blood flows, making a meal of it. Why boobies tolerate this remains a mystery.

No bird is better adapted for climbing up a tree trunk than a woodpecker. The foot of this Pileated Woodpecker is ideal for clinging, and its relatively short legs allow it to anchor itself securely. When traveling upward, the woodpecker’s a master. But hitching down? Not so much — usually they will fly. Nuthatches, however, can easily go up and down. This White-breasted Nuthatch walks over the bark of trees by grasping with one leg while using the other for a prop. It also has a rear-facing toe...

The Cinereous Mourner is a small, ashy-gray bird that lives in the forest understory of the Amazon Basin. And it’s taking mimicry to the next level: when viewed from above, lying alone in its cup-shaped nest, its chick is a near match to a highly toxic caterpillar — one that snakes and monkeys won’t eat. The chick even waves its head like a caterpillar, increasing the illusion. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter. Sign up for BirdNote...

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 (like this Talamanca Hummingbird) 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. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly ne...

Surf Scoters are perfectly at home in the element they’re named for. They swim smack in the middle of what surfers call the impact zone: Just where the waves break with greatest violence. Why risk the harshest waves when there’s calmer water close by? Because the churning action of crashing waves can expose the small clams and crabs that scoters eat. And how do Surf Scoters avoid getting mashed by the sea? When a towering wave is about to crash down, the scoter deftly dives and swims under the c...

When it comes to nests, common sense suggests that large birds build large nests, and small birds build small nests. But in fact, some species of smaller birds build large nests. None, though, builds anything like the communal structures of Sociable Weavers in southern Africa’s arid plains. These House Sparrow-sized birds often live in accommodations with room for up to 500 birds. Each family has its own access hole and tunnel into a chamber within the larger complex. Some structures have persis...

Yellow-eyed Juncos sometimes make a migration of sorts — not from north to south, but from the high mountains to the lowlands or the other way around. It’s called altitudinal migration. In the warm summer months, some Yellow-eyed Juncos prefer to nest at higher elevations, while in winter, the scarcity of food pushes them back down to the valleys.

Have you wondered about the right time to remove your hummingbird feeders during fall? Consider leaving your feeders hanging for a week or two after you’ve seen the last hummingbird of the season, just in case a late migrant stops by to fatten up. However, Anna’s Hummingbirds – like the one pictured here – benefit from feeders year-round. This species is largely non-migratory, residing from California to southern British Columbia.

Even if the name Spix's Macaw doesn’t ring a bell, you might recognize this bird. It’s Blu, from Rio , the animated film! Also known as the Little Blue Macaw, the species went extinct in the wild due to hunting for the pet trade, loss of habitat, and invasive species. However, scientists raised a captive population of Spix’s Macaws from the few remaining wild birds. In 2022, 52 of the captive-raised birds were released into the wild.

John Edmonstone was born on a timber plantation in British Guiana, and enslaved by Scotsman Charles Edmonstone. He learned taxidermy techniques by accompanying a naturalist on expeditions. In Scotland, he became a free man and began working as a taxidermist. One of his students was a teenaged Charles Darwin, who would later use the skills he learned from John to preserve and study the Galapagos birds that formed the basis of his theory of evolution.

Birds have developed many strategies for protecting their young. But only one species can tuck its chicks into pouches under its wings, then fly the young to safety. It’s the Sungrebe of Central and South America. Despite the name, they are not closely related to grebes. Sungrebes swim and dive on quiet freshwater streams. Both sexes incubate the eggs in a nest on branches just above the water. But when the young hatch, naked and helpless, the male takes them under his wing. He’ll swim — and fly...

Blackpoll Warblers make one of the longest migrations taken by a songbird in the world. Blackpoll Warblers that breed in Alaska fly southeast in the fall, appearing throughout the Midwest and eastern U.S. on their way to the Atlantic Coast. Then, they make a nonstop flight over the water to reach South America. Scientists uncovered the stranger-than-fiction details of Blackpoll Warbler migration thanks to a tool called a light-level geolocator, which uses day length to figure out where a bird tr...

It's the time of year that geese migrate south for the winter. Isn't it? So why are there so many geese still hanging around, setting up housekeeping on our parks and golf courses? Did they decide to forgo the long trip north? In the early 1900s, non-migratory geese were brought in by the hundreds to populate wildlife refuges. Now, while many Canada Geese migrate south for the winter, these other geese stay -- and multiply. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe...

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 together and off they go across the water, running on the surface side by side. Standing straight up with necks held high and feet churning like propellers, they no longer look much like grebes - more like p...

A parrot’s eyes are located on the sides of its head. So, if it wants to look at something — say, a delicious piece of fruit — it has to cock its head one way or the other do it. And if it looks with its left eye, then uses its left foot. Scientists call this handedness . That’s when one hand — or foot — is used consistently over the other for doing complex tasks. Sulphur-crested Cockatoos are almost all left-handed ... that is... left-footed. More info and transcript at BirdNote.org . Want more...
