The harsh caws of American Crows are one of the most familiar bird calls in North America. Fish Crows sometimes join flocks of American Crows as they forage for food. The two crow species look similar, but have a distinct call that sounds a bit like an American Crow with a stuffy nose. The Fish Crow is found in much of the eastern U.S. and is spreading to new areas north and west to breed.

In higher animals, the brain is like a Lamborghini — amazing engineering, but expensive to run. In a human, the brain uses about 10 times more energy than other organs. A bird's system is exquisitely attuned to this expense. Several species, including Black-capped Chickadees, have adapted in a clever way. You can usually hear these chickadees calling throughout fall and winter. But they aren’t singing much, because they don’t need to. In their brains, the centers that control how they learn and give voice to songs shrink. But as the birds resume singing during spring, the control centers in the br...

May is the prime month across much of North America to celebrate the return of migratory birds from the tropics. Of all those coming back, it is the warblers that many birders eagerly await. And of the more than 50 species that brighten our spring, many gleam like precious stones. From the sky-blue of the Cerulean Warbler to the golden cloak of this Prothonotary Warbler, these tiny birds dazzle us. Purchasing shade-grown coffee can help these and other warblers!

Does staying cooped up inside with your kids sometimes drive you up the wall? Take comfort in the bird that does it year after year — the hornbill. Each breeding season, a female hornbill plasters herself into her nest cavity, leaving only a thin slot for ventilation and food. She stays there for months to raise her young, while her mate brings her food. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The peace of the vast Guyanan jungle is abruptly broken with the dawn chorus of male Capuchinbirds, one of the most bizarre birds in South America. The singing male bows forward, then suddenly stretches to his full length, raising a monk-like cowl of feathers around his naked blue-gray head. The unmistakable noise attracts female Capuchinbirds, which jostle each other ruthlessly in the quest to get close to the studliest of the displaying males. The alpha male with the best singing technique will be the only one to mate. More info and transcript at BirdNote.org. ...

The fluting song of the Wood Thrush is an ethereal sound of summer in North America. During the breeding season, these robin-sized songsters serenade deciduous forests of the eastern U.S. and Canada. Each fall, they migrate to rainforests from southern Mexico to Panama where they call to each other from the underbrush. For Wood Thrushes, not just any woods will do. They depend on large blocks of intact forest throughout their range. We can help these virtuosic songsters by conserving and restoring woodlands throughout the Americas. That includes planting native trees in urban green spaces and buying bird-friendly...

Dr. Clinton Francis is a sensory ecologist who studies how noise pollution affects birds, like this Black-headed Grosbeak. On the Bring Birds Back podcast, Clinton explains how sounds produced by human infrastructure can really disrupt bird behavior. Although birds rely on hearing to sense predators and prey, and to find mates, their sense of hearing isn’t very good, making them very sensitive to noise pollution from machines and vehicles. Fortunately, there are many ways to help birds by reducing noise pollution. Learn more in season 5 of our long-form show, Bring Birds Back. More info an...

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. ...

While Dara Wilson was working at the Smithsonian’s National Zoo in D.C., she introduced visitors to the Amazonia exhibit. She would describe the song of a bird she’d never had the chance to see in the wild, the Blue-gray Tanager. But when Dara moved to Panama, she heard the song that she knew by heart already. Encountering the Blue-gray Tanager in its natural habitat inspired her to keep learning about birds — and to share that knowledge with others as an educator. Dara helps organize Black Birders Week. Find out how you can participate in this year's event...

Peer into the world of birds, and eyes of many different colors peer back. While eye color isn’t tied to one group of birds or another, a common pattern is a change in eye color as immature birds grow to adulthood. Bald Eagles, Ring-billed Gulls, and ducks such as goldeneyes and scaup have brown eyes as youngsters, and yellow eyes as adults. Red-tailed Hawks reverse this pattern, with their eyes changing from yellow to brown. And the yellow eyes of a young Cooper’s Hawk, pictured here on the right, turn deep red as they reach maturity. Mo...

Loons are built for life in the water – so much so that their legs don’t work well on land. During migration, loons sometimes mistake wet pavement for the reflective surface of deep water and try to land there, then become unable to take flight again. If you see a stranded loon on a road or parking lot, calling a wildlife rehabilitator can help start the process of returning that bird to safety and back on their migratory journey. This episode is brought to you by Wild Delight Bird Food, which aims to support wild bird populations with...

Private Eye Michael Stein investigates a possible break in when a kindly neighbor fears a snake has attacked a nestbox occupied by nesting Great Crested Flycatchers. What he finds is an ingenious way that birds sometimes use a predator’s survival instincts to their own advantage. More info and transcript at BirdNote.org. Want more BirdNote?

For years, nature recordist Lang Elliott came up with clever ways to hear high-pitched bird songs despite his high-frequency hearing loss. Lang teamed up with a programmer to develop an app called Hear Birds Again. Currently it’s only available for iPhones, but it’s able to take high-pitch bird songs and shift them down into a lower range. More info and transcript at BirdNote.org. Want more BirdNote?

Knowing how clever parrots are, researchers wanted to see how they’d respond to another parrot saying hi on a tablet or phone. After being trained how to start a call, many parrots chatted amiably on calls and stayed on for the maximum amount of time. Some birds even seemed to develop friendships, choosing to stay in touch even after the experiment ended.

Milkweed plants are important to Monarch butterflies, which depend on milkweed to raise their caterpillars. But Monarchs aren’t the only ones who benefit from milkweed. Scientists once documented hundreds of insect species they found eating some part of the common milkweed plant – including 132 species of beetles alone. When it’s part of a diverse community of plants, milkweed helps many species find food and shelter, including birds. More info and transcript at BirdNote.org. Want more BirdNote?

It’s National Poetry Month in the U.S., and each year we like to celebrate by sharing our favorite contemporary writers’ work about birds. Ornithologist and poet J. Drew Lanham often writes about racial justice, and his experience as a Black man in the outdoors — both the joy of being in nature and the racism he faces in the field. Sometimes that's led him to birding spots that others might pass by. In this episode, Drew shares a poem inspired by little brown sparrows thriving in overlooked places.

In spring, millions of songbirds — like the Orchard Oriole — migrate north across the Gulf of Mexico, from the Yucatan to the southeastern U.S. When birds encounter storms or headwinds, many may die. Why risk such an end, when they could migrate north along the length of Mexico? It's likely that many birds evolved to take the potentially perilous trans-Gulf route because it is direct and considerably faster, putting the birds on the best breeding territories more quickly. ¡Escuche este episodio en español!

The Scissor-tailed Flycatcher nests in the open country of Texas, Oklahoma, and the south-central region. It's an elegant bird with a slender, deeply forked tail longer than its body. Agile in flight, it can spread and fold its tail, altering the surface area, like an extra pair of wings. When displaying to a female, the male dives again and again, opening and closing his tail. He may even perform a reverse somersault, flashing his pink sides and that long streamer of a tail. ¡Escuche este episodio en BirdNote en Español! More info and transcript at...

The American Tree Sparrow is a common winter visitor in the northern U.S. Despite their name, these sparrows stay close to the ground. When foraging, they’ll kick through leaf litter with their powerful feet, beat seedheads open with their wings or grab a bite from a backyard feeder. Sadly, American Tree Sparrow populations have steeply declined since the 1970s. You can welcome these birds to your neighborhood by growing native plants, keeping cats indoors, and filling bird feeders with a millet-rich seed mix. This episode is dedicated in memory of Pat and Jo Ann Adams of...
