In early fall, you'll see male ducks - like these Mallards - looking very different from when they flew north last spring. The beautiful drakes seem to be gone. But the males are here - sort of "under cover." In mid-summer, they molted into nondescript, dull plumage known as eclipse…

South Polar Skuas glide just off the Pacific Coast each fall. Skuas are prone to piracy, stealing fish from gulls and terns by chasing them down. These birds are also fierce predators on their Antarctic nesting grounds, raiding penguin colonies, eating eggs and young chicks alike. The word…

In September, a streamlined Peregrine Falcon calls as it wings its way south from its Arctic nesting grounds. The pale gray falcon will spend the winter in Chile. On its back, it wears a miniature satellite transmitter, attached there by members of the Falcon Research Group. In 2006, Bud…

In some vineyards of Napa and Sonoma Counties in California, owls patrol by night, and kestrels, harriers, and other raptors take the day-watch. They eat the mice, rats, and gophers that nibble on the roots of young grapevines. Other birds help, too, including this Western Bluebird…

The Bullock's Oriole is the only member of the oriole family that nests in the Northwest. With a slender, sharply pointed bill, the oriole weaves a marvelous pouch-like nest that hangs suspended from its upper rim. The nest hangs downward four to eight inches. The female weaves together…

A dazzling bolt of avian lightning -- a blaze of neon-orange, shooting across a gray, sage-covered hillside on quick wing-beats. It's a Bullock's Oriole, sailing out from its nest among the upper branches of a cottonwood, hunting for insects in the shrubby sage. Bullock's Orioles return…

A White-throated Swift twists and turns, sailing through the air on black, scimitar-shaped wings that span 15 inches. Dashing headlong toward an unyielding wall, the bird disappears at the last second into a slender crevice. The White-throated Swift is aptly named. Flying at tremendous…
