In the mid-1990s, a golden age of fossil discovery began in the Liaoning region of northeast China. The fossils date from 120 to 160 million years ago, when feathered dinosaurs and early birds were flourishing and differentiating. The signature fossil was the world’s first-known feathered…

A Great Bustard shows off to a group of females by inflating special neck sacs – producing what sounds like a massive sneeze followed by a Bronx cheer. He flips his wings almost upside down to reveal bright white undersides, while fanning his tail and long, white throat whiskers. Three…

One male Red-winged Blackbird’s marshland territory may include five—or even as many as fifteen—nesting females. And he makes an effort to mate with every one of them. Biologists call this polygyny - when one male claims breeding rights with multiple females. But while this may look like…

The Ruby-crowned Kinglet is one of North America’s tiniest songbirds. At just four inches long and weighing less than a quarter of an ounce, it’s affectionately known as “Little Rickie,” based on the official four-letter code: RCKI. But the tiny bird has a big voice—the male sings a loud…

The sapsucker is a type of woodpecker that notches rows of small holes in trees, causing sap to well out. The birds eat the sugary liquid flowing from these sapwells. Tree sap is similar in sugar content to the nectar hummingbirds take from flowers. And it is no coincidence that just as…

Of all American presidents, just one might have halted the playing of “Hail to the Chief” so he could listen to an Orchard Oriole singing — Theodore Roosevelt, “the conservation president.” During his presidency, Roosevelt helped establish 51 preserves for birds, five national parks, 18…

A Mourning Dove lies belly down on the soil of a garden bed. It fluffs its feathers, then relaxes its wings, draping them outward to expose fully its back and rump to the morning sun. A great many birds sun themselves, often in postures that give maximum sun exposure to the head, neck, and…

One of the most ethereal of spring sounds is that made by the Wilson's Snipe. Much as if they were playing a reed instrument, the male snipe produces a winnowing sound in flight by metering, with his wings, the flow of air over his tail-feathers. Among the most venerable of practical jokes…

Rossini’s 1815 opera, The Thieving Magpie, tells of a household maid who nearly goes to the gallows for stealing silver from her employers. At the last instant, it’s revealed that the thief was actually a magpie. The opera was so popular in its day that it’s believed to have helped cement…

Tricolored Blackbirds nest primarily in California, but smaller groups breed from the state of Washington to Mexico’s Baja California. They look a lot like Red-winged Blackbirds, except Tricolored males have dark red epaulets and white bars on their wings instead of scarlet epaulets and…
