Since 1976, Project FeederWatch has been through many changes, but what has remained is the dedication to collecting data that improves bird science. Dr. Ashley Dayer is a conservation scientist who leads a research team based on Project FeederWatch data. She says the project is a great opportunity for some birders with disabilities.

In North America, the European Starling has gained a bad reputation for competing with native bird species for nest cavities. But researchers in Ontario, Canada, were surprised to see three Hairy Woodpecker nestlings receiving care from both a female Hairy Woodpecker and a European Starling — a stunning example of a bird caring for another species’ young.

The cries of a Killdeer are familiar across most of the U.S. during spring and summer. But where do they go in winter? Killdeer that breed in the southern half of the US and along the Pacific Coast are year-round residents. But those that breed in the northern U.S. and Canada, where winter conditions are more severe, migrate south to Mexico and Central America. Because the northern Killdeer fly south — right over the region where other Killdeer reside year-round — they are known as leap-frog migrants.

Knowing when to hunker down and when to move on is a matter of survival for the Red-headed Woodpecker. This noisy bird spends its summers taking insects from the sky in flashy, acrobatic flight. But prey is harder to find in winter, and in most years the woodpeckers move south. A bumper crop of acorns and other large seeds in autumn, though, can allow the birds to stock their larders, and many linger in the North.

In the fall, Rusty Blackbirds get new feathers with reddish-gold highlights that have a unique and subtle beauty. Their complex little song might sound like a door hinge that needs some grease. Though once common, Rusty Blackbirds have lost over 90 percent of their population since 1966 – one of the steepest declines of any North American bird species.

A stiff December breeze blowing down the Columbia River delivers an exhilarating chill. A stretch of river near Bridgeport, in north-central Washington, is held tightly by a series of dams, creating massive lakes. High on an overlook, a Bald Eagle watches a flock of birds – coots, ducks, and more – on the water below.

Songbirds delight us with their music, but at times they might sound repetitive. That’s because songbirds have to practice their singing to keep performing at their best. Researchers studying Zebra Finches found that females preferred the songs of males that had been practicing consistently compared to males that had taken a break from singing for a few days. So it seems that birds must keep their vocal muscles in shape to make sure everyone hears them loud and clear.

The Northern Shrike breeds in the tundra and taiga of the north, but migrates south into the lower 48 for the winter. It has a pleasing and rhythmical song, which it sings even in winter. But its song belies a rather bloodthirsty feeding habit. The shrike impales its prey on sharp thorns or barbed wire, where it can pull it apart and consume it.

Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters. But cardinals used to be Southern birds. By the second half of the 20th century, though, they were nesting as far north as Maine, the northern Midwest, and even southern Canada.
