Along the Gulf of Mexico, you’ll find undeveloped sandy flats and shallow lagoons. This is prime habitat for Wilson’s Plovers to nest and raise their chicks. But life on the beach can be tough for birds. In many parts of its U.S. range on the Gulf and south Atlantic coasts, Wilson’s Plover…

Summer Tanagers snatch bees and wasps in mid-air, as they buzz about. Bug in beak, the bird flies to a perch, slams the insect against a branch until it’s dead, then wipes it against the branch to remove the stinger before eating it. Summer Tanagers will also tear open paper-like wasp…

Many of the waterbirds that winter along the coasts of the Lower 48 spend their summers breeding on tundra ponds and lakes. Loons, grebes, scoters and others call throughout the long summer days. Together, their voices create a symphony that evokes the Arctic north.

The dawn chorus is that time when, just before sunrise, birds begin to sing. One by one, then all together, their voices join to greet the new day. But which bird sings first? The timing of when a bird joins the chorus seems to depend on how well it can see in low light. So the birds with…

We've all seen sandpipers foraging busily on mudflats or at the ocean's edge. But this Lesser Yellowlegs often carols from the top of a tall conifer in its nesting territory in Alaska. The name "sandpiper" actually comes from the voices of these birds, rather than from their long-billed…

If a bird’s feathers get too dried out, they become brittle. To prevent that from happening, most birds have a gland located above the base of the tail that produces oil. They use their beaks to massage oil from the gland into their feathers to keep them supple. A bird first grips a…

Cypress trees draped with Spanish moss rise from still, dark water. A Barred Owl hoots mightily as an alligator slithers by. It's morning on the bayou. Bayous are found in much of the Southeast from Arkansas to Alabama, across flat land that drains into the Mississippi River. A bayou's…

The tiniest bird in mainland North America: the Calliope Hummingbird - a 3-1/4-inch jewel, weighing in at just a tenth of an ounce. These birds migrate north each spring from Western Mexico. From its perch, a male Calliope Hummingbird surveys its territory. This exquisite bird was named…

In a Western ponderosa pine savanna, tall pines dot an open, grassy landscape. A Western Bluebird flits from a gnarly branch, as this Cassin's Finch belts out a rapid song. The trees here grow singly or in small stands. Upslope, the pines become denser, mixing with firs. Downhill, the…

In spring, a male Sooty Grouse calls from a concealed perch high in a tall conifer. Known as “hooting,” it’s a very low-pitched, five or six-note thunking sound. When a female cackles in response, the male flies down and displays to her by strutting and fanning his tail. Females are…
