Long-billed Curlews are the largest shorebirds in North America. In his courtship display, the male Long-billed Curlew flies a series of arcs across the sky, calling as he goes. Outside of the breeding season, they roost and forage in mixed flocks. When the flock is disturbed, the curlews’ loud flight calls sound the alarm that a potential predator is near.

This episode is brought to you in loving memory of former BirdNote Board member Tom Darden, with thanks to his family for their support.

The colorful feathers and loud songs of male songbirds often catch a birder’s attention first. Observing females often means birding more slowly, noticing subtle differences in plumage and behavior, says Joanna Wu, who’s part of a group called the Galbatrosses that’s encouraging birders to spend more time identifying female birds. Fellow Galbatross Purbita Saha says that watching for females can help us understand birds on a deeper level by observing them as individuals rather than just species.

David Sibley’s paintings connect millions of people with the lives of birds. His talent in observing and portraying birds culminated in The Sibley Guide to Birds. Sibley describes how he learned to sketch and illustrate birds such as this Townsend’s Warbler: "I spent years in the field, just traveling and birding and sketching," he says. “The drawing was so important to me, that there was never any question in my mind of continuing to paint the birds. It’s how I study the birds." Watch David Sibley sketch a Townsend's Warbler in the BirdNote studio!

Some birds, such as the Northern Bobwhite, get their name from their songs or vocalizations: "Bobwhite! Bobwhite!" The Killdeer is another bird named for its song: "Kill-dee, kill-dee, kill-dee." There are others. "Poorwill, poorwill, poorwill," says this Common Poorwill. This bird is the cousin of the Whip-poor-will, another bird that calls its own name.

On a hot summer’s day, watch a bird such as a crow — or this Bald Eagle — very carefully. You’ll never see them sweat, because birds don’t have sweat glands. So how do they keep cool? One way is panting. As the bird breathes rapidly, heat is carried out of its body through the lungs and air sacs. Bare skin on the legs, face, and beak also help with cooling. So do puffing out feathers, fluttering wings, or splashing in a puddle or birdbath. And soaring birds like hawks can simply ride the updrafts far above ground to cooler air.

The Tower of London has a long and notorious history of murderous political intrigue, dungeons, and famous beheadings. And for more than 300 years, the tower has also been home to a set of royally maintained ravens. Since the time of Charles II, at least six ravens have — by royal decree — made their home in the tower. They are given ample food, comfy quarters, and private burials in the moat near Traitor's Gate.

Brown Pelicans fly just above the surface of the water. They circle high, then diving headfirst, plunge under water to catch fish. But doesn't that hurt? Several adaptations protect pelicans as they dive. First, they have air sacs beneath the skin on their breasts, which act as cushions. Pelicans have also learned that a steep dive angle, reduces aiming errors caused by water surface refraction.

Gambel’s Quail and California Quail are both well known for the comma-shaped tuft of inky black feathers poised atop the crown of their heads. For both species, this decorative “topknot” is formed from six individual feathers that contour together into a single structure. Yet they’re hardly the only quail with a fashionable updo. Though we don’t know exactly why so many quail evolved elaborate headdresses, they may help the birds attract a mate or intimidate competitors.

By late summer, the male Mallard’s need for fancy feathers to attract the females has passed. These birds have molted, and their bright feathers are replaced with mottled brown ones. Subdued colors help camouflage the male ducks, protecting them from predators. Come fall, the male Mallards will molt again and become the colorful dandies we remember.
