Hummingbirds are built for hovering flight, with flexible wrists that rotate their wings in a rapid figure-eight motion that generates almost constant lift. Eurasian Skylarks, on the other hand, hover by fluttering their wings 10-12 times per second, singing all the while. Some raptors such as American Kestrels use a different strategy: by flying into the wind, they can float in place while they...

The Golden-cheeked Warbler is an endangered species and the only bird that nests exclusively in central Texas. Males arrive in March to stake out a territory in the juniper-oak woodlands – the older the trees, the better! By the end of July, the warblers are on their way back to mountain forests of southern Mexico and Central America. Sadly, deforestation has destroyed and fragmented much of...

Outdoor cats are one of the biggest threats to birds, killing over a billion a year in North America. And indoor-outdoor cats live much shorter lives than indoor-only cats. So keeping a cat indoors helps protect birds. And there are plenty of ways to make the “great indoors” more exciting for your cat. In this episode, BirdNote senior producer Mark Bramhill shares his experience with his cat,...

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. This...

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...

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...

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....

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...

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...

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...
