One of the world champions of long-distance migration is the Arctic Tern. Arctic Terns nest across the far northern reaches of the continent during our summer, then fly south to Antarctica for the rest of the year. Some will circle the polar ice-pack before heading north again, completing…

Emily Dickinson: "The Birds begun at Four o'clock..." As the first rays of sunlight fill the trees on a spring morning, a symphony of birdsong erupts. As early morning light extinguishes the stars, male birds begin to belt out their songs. One of the magical gifts of spring is the dawn…

In winter, a foraging flock might include several species of birds: chickadees, kinglets, and even a Downy Woodpecker. Many bird species eat alone, so you might wonder why these birds have chosen to dine together. Different species foraging in a group to find food enhances the success of…

American Coots settle onto lakes and estuaries, forming rafts of hundreds, even thousands, of birds. They like to feed on aquatic vegetation, and sometimes they lumber ashore to nibble at grasses and agricultural crops. The coot's lobed toes help it swim and maneuver under water. To get…

Driving the freeway or a narrow country road, you may glance up at a light pole where a large hawk sits in plain view. If it's brown and somewhat mottled, and its small head and short tail make it appear football-shaped, it's probably a Red-tailed Hawk. During winter, many Red-tailed Hawks…

During December, birds spend the long, cold nights in a protected place, sheltered from rain and safe from nighttime predators. Small forest birds, such as nuthatches and creepers, may spend the night huddled together in tree cavities. Birds like this male Mallard fluff up their feathers…

With its awe-inspiring vistas and eons of geologic time on display, the Grand Canyon also offers a unique habitat for birds. What you're likely to see first is this Bronzed Cowbird, strutting on the lawn of a lodge or restaurant. Common Ravens call and squabble. If you're lucky, you may…

Did food play a role in your courtship? Well, Arctic Terns share a food-related ritual. Early in the breeding season, a female Arctic Tern perches near a possible nesting site. The male appears carrying a small fish in its bill. The female pauses for a few minutes to “check him out” before…

After hatching, baby robins spend up to 15 days in the nest. By July, many young American Robins have left the nest, or fledged. But they aren't ready to make it entirely on their own yet, and they follow their parents around, learning to fend for themselves. Outside of the breeding season…

Both this Eastern Towhee and the Spotted Towhee of the West sport a black or dark brown hood and back. And when they fly, their tails flash white. When a hawk gives chase, the towhee's flashing tail-feathers draw the predator's attention. Momentarily distracted, the hawk may come up with…
