Scientists have found that, at least for some species, a bird’s genes dictate the route it takes when it migrates. For instance, when subspecies of Swainson’s Thrushes interbreed and produce hybrid offspring, those young birds may take mom’s route north and dad’s route south or zigzag…

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…

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.

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…

A hike through the mountains of the West, from the lowlands to the rocky alpine zones, reveals an incredibly diverse array of beautiful birds: Swainson’s Thrushes, Pine Grosbeaks, American Pipits and so many more to be found.

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…

In summer, across much of North America, a sudden flash of orange and black in the treetops usually means one thing: orioles. Baltimore Orioles (like this one) in the East, Bullock’s Orioles in the West, and Hooded Orioles in the Southwest and California. These vividly colored birds return…

Generations of birders have puzzled over how to tell Downy Woodpeckers from Hairy Woodpeckers. The two species’ patterns of black and white feathers are so alike that it was long thought they were the closest of relatives. The two live in similar woods, nest in similar trees, and eat many…

The real James Bond was born in Philadelphia in 1900 and worked as a banker after college. But his first love was the natural world. Eventually, he kissed the banking world goodbye and dedicated the rest of his life to exploring and documenting birds and nature.
