Ruby-throated Hummingbirds are the only hummingbirds that nest in the Eastern states. Most Ruby-throats spend the winter in Central America. By March, some males are already returning to the Southeast. But it's well into April before they reach the northern states. Female hummingbirds…

A Red-tailed Hawk soars on broad, rounded wings, the epitome of effortless flight. Without flapping, it traces a leisurely, rising circle. The hawk is riding a thermal, a column of warm rising air generated near the earth's surface by heat from the sun. The Red-tail periodically circles to…

The ancient Greeks and Egyptians described a mythical bird called the Phoenix, a magnificent creature that was a symbol of renewal and rebirth. According to legend, each Phoenix lived for 500 years, and only one Phoenix lived at a time. Just before its time was up, the Phoenix built a nest…

One of the most musical and complex bird songs in the U.S. is that of the Brewer's Sparrow. It's a veritable aria, ringing forth from the sagebrush of Eastern Washington's Columbia Basin. Shrub-steppe is disappearing from the interior west as it is cleared for irrigated crops. The…

The White-crowned Sparrow pours out its song over and over on spring and summer days-and even on moonlit nights-often up to 15 times a minute. Now here's a curious thing: Just as people in different regions may have different dialects, White-crowns have different songs, according to where…

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…

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…

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…

People often say that spring “bursts” forth. But this seasonal change isn’t like flipping a switch. It’s more like a series of waves breaking slowly. Robins and bluebirds return north in March. During April, more songbirds migrate north from the tropics, adding to spring’s growing chorus…

Birds are often admired for their ability to fly. But braking just in time to avoid a crash landing is amazing by itself. How does a robin go from full-out flight to a dead stop at a tree? If we could watch in slow motion, we’d see it raising the angle of its wings higher and higher from…
