Like the American Robin, the European Robin is a bird of yards and gardens. But it’s not much bigger than a chickadee. The robin’s likeness turns up everywhere from Mother Goose rhymes, Peter Rabbit stories, and whiskey labels to postage stamps and Christmas cards. On at least two…

On a snow-covered field in northern Japan, two majestic Red-crowned Cranes face one another, raise their heads toward the sky, and call in unison. As they call, the pair begins to dance. They bow to one another, then throw their heads over their backs, then bow again. The pair leaps into…

Looking for a project this winter? Consider giving screech-owls a helping hand. Eastern and Western Screech-Owls span the wooded areas of the continent, nesting in tree cavities left vacant by large woodpeckers. However, such natural housing opportunities are often in short supply. That’s…

Have you ever seen a bird foraging in the rain and wondered why it isn't soaked to the bone? While every bird wears one feather coat, different kinds of feathers – and even different parts of the same feather – can perform various functions. The outermost tips of the main body feathers…

Rhinoceros Hornbills are among the largest of the world’s 54 species of hornbills, which are spread across Africa and India to Asia and New Guinea. Some hornbills eat mostly fruit. Others are carnivorous, snapping up lizards, small mammals, and birds. Most live in mature, tropical forests…

In winter, flocks of American Robins spend the night together. Typically, a few dozen to a few hundred birds roost communally in trees or an old barn, or under a bridge. But larger robin roosts can number in the thousands, or even tens of thousands! In 2007, observers near St. Petersburg…

When a Northern Flicker takes flight, a bold patch of white feathers flashes on its rump, in contrast to its brown body. This white rump likely evolved as an anti-predator adaptation. A hawk flying in pursuit of a flicker may focus on the white spot rather than the darker image of the…

Eared Grebes eat brine shrimp and aquatic insects for sustenance, but rigid exoskeletons make them hard to digest. So these grebes -- along with their other grebe cousins -- evolved to use their feathers as a way to slow down digestion. The feathers form dense balls in the digestive tract…

After carving a nest cavity in a living tree, which can take a year or more, Red-cockaded Woodpeckers peck holes around the nest, causing sap to flow downward. This creates a barrier to thwart hungry snakes. The mature longleaf pine woods where these endangered birds live are shrinking…

Many bird songs are rich and complex, difficult to remember, and nearly impossible to imitate. Some species' songs, however, sound as if they could have been whistled by a human. These simpler, pure-noted songs are some of the most familiar and easy to remember. These songs -- including…
