You'd think that with so much green in nature, many birds would be a'wearin' the green for camouflage. Not just on St. Patrick's Day, but every day. Yet very few of our birds cavort in Irish green. There be some wee exceptions, however - some of the hummingbirds, with their backs of bright…

You can find European Starlings in huge flocks from coast to coast, and from Northern Canada deep into Mexico. Yet not one of these iridescent-black, yellow-billed starlings is native to the Americas. One hundred starlings were released in Central Park in New York City in 1890. From that…

The swallows that make mud nests in spring and catch flying insects all summer are now far south in Mexico, and Central and South America. It's only as recently as the end of the nineteenth century that ornithologists agreed that swallows, including this Cliff Swallow, migrate. Many…

By this time in September, most migratory birds have departed. Many resident birds remain, but their voices are now quiet. During fall and winter, birds don't need to sing to establish a breeding territory or attract a mate. Many songbirds lose the ability to sing. The part of the brain…

A Rock Pigeon bobs its head as it walks, making it appear that its head and feet are linked. Pigeons' eyes are on the sides of their heads, permitting them to watch for predators from all directions, but limiting their ability to distinguish distances. To compensate, these birds move their…

Immature Bald Eagles look so different from mature Bald Eagles that John James Audubon thought they were a different species entirely! Sitting about three feet tall, these majestic birds have wingspans of more than six feet. Stretch your arms as far as you can, and imagine a bird whose…
