During the winter of 2009-2010, thousands of Brown Pelicans washed ashore on Pacific beaches, wet, cold, starving. Fierce storms, thought to be more frequent because of global climate change, probably made it difficult for the birds to feed. And storm-water runoff washed oil and pollutants…

"Peregrine" means "wanderer." And Island Girl, a Peregrine Falcon, has made the 18,000-mile round-trip journey from the high arctic of Canada to southern Chile three times. Bud Anderson of the Falcon Research Group calls her "a master of the air." Using satellite telemetry, he invites…

Despite their seeming abundance, the numbers of Common Grackles have shrunk by 60% in the last 40 years. Grackles prefer open landscapes with scattered trees, and their numbers peaked as eastern forests were cleared for agriculture in the 18th and 19th Centuries. As eastern forests grew…

How do birds navigate? They steer by landmarks and by the sun and stars. A keen sense of smell helps some birds chart their course. And, it turns out, migrating birds also find their way by responding to the magnetic field of the earth. Iron-rich magnetic crystals inside the upper beak of…

Like their cousins, jays and crows, the Yellow-billed Magpies of California were hit hard by West Nile virus. The disease reduced magpie numbers by half. Habitat loss and poisoning also threaten the birds. They're now on Audubon's watchlist of species of concern. Whether the magpies will…

This January marks the 75th anniversary of Ducks Unlimited. Ducks Unlimited - or DU - has grown to become, by many measures, the most effective wetland conservation organization in the world. To date, they've conserved more than 12 million acres of waterfowl and wildlife habitat in North…

In September 2011, the research vessel Searcher sailed for Laysan Island from the Hawaiian island of Nihoa. It carried eight biologists from American Bird Conservancy and the U.S. Fish and Wildlife Service - and 24 Millerbirds. Laysan was once home to Millerbirds, but they disappeared long…

On the north shore of Kaua'i, endangered seabirds called Newell's Shearwaters nest in the mountains. After sunset, shearwaters fly out from the highlands to the ocean, using the moon's reflection on the sea to guide them. But some mistakenly fly toward streetlights, lighted resorts, and…

Once abundant on Bermuda, Bermuda Petrels - also known as Cahows - were drastically reduced by human harvesting and introduced predators. From the early 1960s and for the next 40 years, David Wingate dedicated his life to helping the Cahow regain a solid foothold. He ran the conservation…
