Harpy Eagles spend their lives in tall, remote tropical forests in Central and South America, flying from tree to tree in search of food. The eagles are named for the Harpies of Greek mythology, women with the bodies of birds who, on Zeus’s command, snatched people from the earth. Since it…

The natural world sends us messages if we’re open to receiving them. Ancient navigators put their trust in the birds’ amazing ability to find dry land, no matter how far they were from safe harbor.

A crow named Betty learned how to take a straight piece of wire and bend one end into a hook. She then used the hooked end to haul a tiny bucket of meat from the bottom of a long tube. A postage stamp was issued in honor of this New Caledonian Crow. Watch a video of Betty - we've provided…

Since 1929, Michigan’s state bird has been the American Robin. But lots of people think it’s time for a change. The Black-capped Chickadee is a popular favorite, as is the endangered Kirtland’s Warbler. But it turns out that it’s pretty hard to get a state bird changed.

Sometimes populations of birds split apart - a process called speciation. Where Baltimore Orioles and Bullock’s Orioles overlap in the Great Plains they produce hybrid offspring. But these hybrids don’t live very long or spread very far. Are these two birds different species?

For many birds, breeding and nesting are tied closely to spring. But for a bird like the White Ibis — one of the most abundant wading birds in the Southeast — the timing of nesting has to do with water. White Ibises forage in shallow pools of fresh water, especially for crayfish and small…

When young hens begin laying at five or six months, their ovaries aren’t fully in synch. So every hundred or so eggs, they release two yolks instead of one. Double-yolk eggs are usually a little bit larger than average, so if you’re looking to get one, try buying the extra-large or jumbo…
