When glaciers pushed south into what is now the U.S. around 20,000 years ago, they scraped off the soil layer and spelled the end of native earthworms except in the southern states. So the earthworm plucked by the robin in the park or on your lawn is probably a relatively new arrival, most likely a

With his brilliantly colored plumage fanned out in display, a tom (male) Wild Turkey is a handsome sight to behold. He has a bright red head, long spurs, and… a beard. This “beard” is a small cluster of bristles that sprouts from his chest plumage. It looks like a misplaced ponytail. The older the

Common Yellowthroats are one of the most abundant warblers in North America. They’re adaptable birds, thriving in places that pickier warblers pass over. So it’s easy to find yellowthroats in urban areas. Check for them in marshes, overgrown fields, and brushy areas along streams or trails.

Many species have black feathers on the trailing edge of their wings, regardless of what color most of their feathers are. Birds as different as gulls, pelicans, storks, and flamingos all have black-tipped wings. These flight feathers are rich in a pigment called melanin. But melanin doesn’t just

Here they come! Rufous Hummingbirds, Black-chins, Broad-bills, Ruby-throats, and others are migrating north after a hot, dry winter in sunny Mexico or Central America. And they’re ready for a drink. You can help these thirsty birds by hanging a hummingbird feeder filled with the right kind of nectar

Cuando es predecible y la vida silvestre está bien adaptada, una inundación natural puede generar prosperidad biológica. En la cuenca del río Amazonas, que contiene una quinta parte del agua fresca del mundo, las lluvias anuales pueden aumentar el nivel del agua entre 9 y 12 metros en cuestión de

Standing less than six inches tall, with gray feathers and big yellow eyes, the Elf Owl weighs less than an ounce and a half — that’s a bit less than a golf ball. But don’t let their size fool you. The Elf Owl hunts beetles, crickets, and spiders, plus the odd lizard or mouse. Even larger prey like

At sunset, the male American Woodcock – a plump, robin-sized bird – walks slowly on short legs from the cover of the forest to a nearby clearing. After a few sharp calls, the woodcock takes flight. As he spirals upward, slim, stiff feathers at his wingtips create a curious twittering. At the apex of

Birds evolved not only wings, but many other adaptations that make it possible to fly. Feathers provide insulation, waterproofing, and a lightweight means to become airborne. Birds have honeycombed or hollow bones, reducing body weight. And instead of weighty jawbones and teeth, birds evolved a
