On September 1, 1914, Martha, the last known Passenger Pigeon, died in the Cincinnati Zoo. It’s hard to believe there were billions of Passenger Pigeons in the early nineteenth century. By 1900, there were none left in the wild. The last Passenger Pigeon became a symbol of how easily we…

The Virginia Rail is a secretive bird, a relative of coots and cranes. And it's a bird you'll more often hear than spy. The rail takes its name from its narrow body - "as skinny as a rail" - an adaptation to its favorite marshy habitats. A Virginia Rail walks hidden, squeezing through…

Every spring, birds like this Orchard Oriole and many others are arriving after a long flight across the Gulf of Mexico. Beginning in 1998, a handful of observers -- each assigned to a different oil platform -- began to monitor bird migration between March and May, as far as 100 miles out…

A trip to the moon would mean a flight of 239,000 miles, roughly the same as circling the Earth 10 times. This Red Knot, named B95 for its band number, is nicknamed "Moonbird." Why? This male sandpiper was first banded in 1995 and spotted again -- on his migration through New Jersey -- in…

In spring, millions of songbirds - like this Orchard Oriole - migrate north across the Gulf of Mexico, from the Yucatan to the southeastern US. When birds encounter storms or headwinds, many may die. Why risk such an end, when they could migrate north along the length of Mexico? It's…

Most birds possess the ability to see color. But birds can also see in the ultraviolet spectrum. Hummingbirds - like this Violet-crowned Hummingbird - may zero in on certain flowers because their petals strongly reflect in the ultraviolet range. Migrating birds may use ultraviolet light to…

A hawk dives into your yard, and a frightened robin slams against a window, mistaking the transparent rectangle for an escape route. But you can help. Fold its wings gently over its body in their natural position, grasp the bird lightly, and wrap it loosely several times in the towel. Keep…

From its lofty outlook, this Red-tailed Hawk commands "a bird's eye view." The Oxford English Dictionary defines that as "a view of a landscape from above, such as is presented to the eye of a bird." Debate continues about birds' visual acuity, but we do know that visual acuity is keenest…

Fossils discovered in China reveal the largest feathered animal yet known. Gigantoraptor was a very birdlike dinosaur, yet tall enough to look a Tyrannosaurus rex in the eye. Feathered but flightless, it strode the earth on long legs that likely made it a very fast runner. This…

Imagine the nesting cliff of Common Murres, 100 feet above the ocean. Suddenly, a small murre chick, only three weeks old and just one-quarter the weight of an adult, lunges off the cliff, gliding clumsily to the water below. Soon other chicks follow, splashing into the sea. The chicks'…
