Gentoo Penguins live in the frigid waters of the Atlantic. Only recently have scientists begun to unravel why penguin feathers don’t freeze. An electron microscope revealed tiny pores on the feathers that trap air, making the surface water repellent. This feature, plus a special coating…

The Cuban Giant Owl, now extinct, was 3½ feet tall and weighed 20 pounds — the largest of all known owls. It had very small wings, running after its prey on long, powerful legs. Similar large owls, with long legs and small wings, have been unearthed in places as disparate as Georgia and…

Pigeons — and other birds with eyes on the sides of their heads — have a different view of the world from that of creatures with forward-facing eyes. The images from a pigeon’s eyes overlap slightly, so the bird can see in front of itself, even though it has worse depth perception. But…

Birds like male turkeys or barnyard roosters have a wrinkly, bumpy flap of red skin called a wattle. But what are wattles for? Birds can’t sweat, so wattles help release excess heat. Wattles are also key to courtship displays. Many other birds, including some storks and plovers, also have…

The Red-backed Fairy-Wren, a tiny songbird living in the Australian scrublands, is highly territorial and promiscuous. The male can’t be sure the eggs in his nest are his own. One way to help avoid this problem? The male may rough up a rival who approaches his territory. But research shows…

It takes a lot to bring you the rich sounds of birds yodeling, cooing, and screeching to you each day. It's a meticulous process of researching, writing, fact-checking, editing, recording and sound design. That’s all done by our in-house production team! BirdNote is a non-profit…

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…

Some of the tiniest birds in the world have impressively loud voices. The Ruby-crowned Kinglet — that bright-headed sprite of the treetops — would be downright deafening if it were just a little bigger. Hummingbirds were originally named for the mechanical buzzing produced by their…

From chickadees to Cooper’s Hawks, most birds love a good bath. Some birds get the fluids they need from their food, but many birds need a drink at least twice a day. Water is essential for birds, and supplying clean water for them to drink and bathe in is a great way to help maintain…
