Here and there along winter shorelines, little flocks of pale, silvery shorebirds probe at the water's edge, keeping pace with each wave's ebb and flow. These are Sanderlings, small sandpipers that stay through the winter. Rachel Carson, in Under the Sea Wind, described Sanderlings as…

The 22-inch Great Horned Owl has two tufts of feathers that stick up from the top of its head. This owl is difficult to see, but it's often heard during dark winter evenings and pre-dawn mornings. A pair of owls may call back and forth or overlap their hoots. The male's call is slightly…

Nuthatches rank high on the list of favorite backyard birds. Compact and stub-tailed, they climb down tree trunks and along the underside of branches with comical ease. One at a time, they flit in for suet and sunflower seeds. But out in the woods, where they spend most of their time…

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…

Many jays, including this California Scrub-Jay, store food for sustenance in harsher seasons. An individual bird may cache nuts, insects, and even worms in several thousand spots. If jays visit your yard, here’s a game you can play with them. Each day, preferably when the jays aren’t…

A fine woodworker has a chest full of tools, each designed for a specific task. Birds also have highly refined tools-their bills. The size and shape of a bird's bill match perfectly the food they seek and the way in which they obtain their meals. Different species of shorebirds that forage…

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).

What does the Pacific Wren hear in a song? It's a long story. What we hear as a blur of sound, the bird hears as a precise sequence of sounds, the visual equivalent of seeing a movie as a series of still pictures. That birds can hear the fine structure of song so acutely allows them to…

No bird is better adapted for climbing up a tree trunk than a woodpecker. The foot of this Pileated Woodpecker is ideal for clinging, and its relatively short legs allow it to anchor itself securely. When traveling upward, the woodpecker’s a master. But hitching down? Not so much — usually…

Crow experts think big communal roosts provide warmth, protection from predators, shared knowledge about food sources, and a chance to find a mate. Follow crows to their roost some autumn evening, if you can, and watch these avian acrobats wheel in for the night. Find out what’s new with…
