Some ducks don't sound like ducks at all. Some â like the Harlequin â squeak. Harlequins are unique in other ways, too. Quick and agile in rushing white water, they dive to the bottom of mountain streams for food, and use fast-flowing rivers for breeding. If you're lucky enough to spot a Harlequin Duck, you may guess how it got its name. Dressed in vivid multi-colored patches, "harlequin" is the jester of traditional Italian comedy.

Hummingbirds use their long tongues to sip nectar from flowers. Theyâre able to roll their tongues into a tube-like shape. Since the 1800s, scientists thought those tongues worked through capillary action, like how water instantly rises into a straw in a full cup. But when scientists spent years using slow-motion cameras to capture hummingbirds drinking in greater detail, they uncovered a completely different story: the tongues act like a tiny but powerful pump.

By carrying more people in a single vehicle, mass transit can use less energy than cars. Taking steps to reduce greenhouse gas emissions can help the hundreds of bird species put at risk by climate change. Not to mention, you can do a little birding on the commute â on the way to the bus or train stop, and on the ride itself.

Helmeted Guineafowl are known for moving in frantic flocks, often running and squawking about. In their native range â from Senegal to South Africa â these chicken-sized birds are favored prey of wild cats and Martial Eagles, so they need to be alert! Because theyâre also spooked by unfamiliar people, guineafowl are often employed as burglar alarms on farms.

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes canât: the owlâs flight feathers glow with ultraviolet light. Itâs invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the reason for the owlsâ glowing feathers still isnât clear. However, scientists realized that they could estimate an owlâs age based on the pattern of luminescent color on the wings, which changes predictably as birds grow and replace their feathers.

Although the American Crow may seem indifferent about pillaging another bird's nest, they regard a threat to their own young as a punishable offense. To protect their nest, adult crows dive-bomb people, cats, other animals, and even other birds. Young crows fledge when they are around five or six weeks old, and their parents continue to care for them for months.

At this time of year, a very young male Bewick's Wren is beginning to learn how to sing. His father sings a crisp well-defined song, separated by pauses, but the young bird's song is fuzzy, unfocused, a little rambling. Each adult male Bewick's Wren has his own set of unique songs. A young wren grows up learning his father's songs. But when young bird matures and moves to its own new territory, it will leave behind the song of its father to create a song that sounds more like its new neighbors. The better to compete for a mate!

Not all blackbirds are mostly black. This Baltimore Oriole is orange! The bird's common name is a nod to Sir George Calvert, First Lord of Baltimore, whose coat-of-arms carried a gold and black design. In spring and summer, you may see these orioles in the Midwest and eastern U.S., lighting up the trees where they nest. If you're lucky enough to live near Baltimore Orioles, entice them to your feeder with half an orange.

After David Shephard moved to Hawaiâi to study botany, he realized that the âmain characterâ of the islands is birds â many plants have co-evolved with birds due to their central role in Hawaiian ecosystems. He now designs Aloha Shirts that feature the native plants and wildlife of Hawaiâi, including the âiâiwi, a bird that has cultural significance for Hawaiians.

Noticeably smaller than Mallards, Blue-winged Teal wings have large patches of powder blue edged in emerald. Blue-winged Teal are long-distance migrants, traveling from nesting areas in Canada and the U.S. to South America for the winter. They feed in shallow water with a preference for snails and fly larvae. In fall and winter they seek out plant matter, especially seeds.

The Okefenokee National Wildlife Refuge was set aside to protect the fabled Okefenokee Swamp of Georgia and Florida. Tall cypress trees and Spanish moss give the swamp a prehistoric appearance. The Prothonotary Warbler is one of the most striking of the swampâs denizens. Having wintered in the West Indies, a male might return to the Okefenokee and establish a breeding territory. Because it lives down in the realm of trunks and branches rather than up in the leaves, the Prothonotary has adopted an unusual nesting habit for a warbler: it nests in natural crevices or old Downy Woodpecker holes!

Tree Swallows glisten in the June sunlight, as they swoop and glide, their arcs interlacing in the air. When a white feather flutters down among them, one swallow snatches the feather in its bill and flies upward, as another gives chase. After a moment, the lead bird lets loose the feather, which drifts lazily, until the second bird swoops to catch it in midair. Loose feathers are important for Tree Swallows. They line their nests thickly with them.
