The tiny Common Redpoll, one of the smallest members of the finch family, weighs only as much as four pennies, yet it survives the cold and darkness of winter in the far North. Most birds depart in autumn to warmer climes. But redpolls feed on birch and alder seeds that are available…

If a young American Robin survives its first winter, its chances of survival go up. But robins still don’t live very long. The oldest robins in your yard might be about three years old (although thanks to banding, we know of one bird that lived to be almost 14).

When a pair of Western Grebes decides it’s time to mate, they call loudly and approach one another. Each bird curves, then straightens, its long neck gracefully. They then face each other, necks on the water’s surface, their bills flipping up drops of water. If attraction prevails, they…

Many Brown-headed Nuthatches make their home in the tall longleaf pines of the Apalachicola National Forest in Florida. Twittering constantly, the birds probe for tiny insects or extract seeds from cones in the trees’ upper branches. Forests of longleaf pine once dominated the sandy…

Like most juvenile shorebirds, this young Black-bellied Plover was abandoned by parents that began their southbound flights from the Arctic National Wildlife Refuge a few weeks earlier. It will join other young Black-bellied Plovers as they make their way south. This little flock of birds…

When birds like these Dunlin form flocks, each individual is less likely to be captured by a predator. Some shorebirds that forage with their heads down, like godwits, will flock with birds that forage with their heads up, like curlews. Still other birds work together — like American White…

One of two species of cuckoos in North America, the Yellow-billed Cuckoo, pictured here, lives in broadleaf forests throughout the East and riparian stands in the Southwest. They were common breeding birds in the Pacific Northwest as late as the 1920s, but then they disappeared. The Black…

California's Salton Sea is hot and smelly - and it's also a Mecca for thousands of wintering birds. This inland sea formed when the Colorado River breached floodgates in 1905, forming a lake 45 miles long. The lake has diminished in size and greatly increased in salt concentration, but a…

National Audubon's Corkscrew Swamp Sanctuary is birdy at any time of year. But in winter, this mixture of cypress swamp and pineland comes alive with migratory songbirds. On a warm, sunny morning, birds are active all around, from the tops of the tall cypresses to the shrubs along the…
