The song of the Black-capped Chickadee pretty much the same throughout the U.S. and Canada — with just a few exceptions, like on some Massachusetts islands. Chickadees on Martha’s Vineyard and tiny Tuckernuck Island nearby have developed songs entirely their own. It’s likely that the birds…

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…

The songs of two common finches provide a steady soundtrack in cities across North America: the House Finch and the American Goldfinch. While they can sound similar, a couple of key features help set them apart. House Finches sing sweetly but often have a sharp, buzzy note near the end…

A pair of Bald Eagles will reuse their nest each year and repair it with new tree branches. But recently in British Columbia, scientists came across an eagle nest made largely out of dried kelp. Back in the ‘90s, that very nest had been made out of tree branches. What changed? Sea Otters…

As most young male birds get ready to leave the nest, they learn their species’ song by hearing their male parent sing it again and again. They imprint on their father’s song. So how does a Brown-headed Cowbird, raised by parents of a different species, learn to sing the correct song? The…

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…

Found throughout North America, the common sunflower can grow up to ten feet high, towering over other herbs and grasses. And that’s only half the story: their roots can reach just as deep in the soil. They’re rugged, adaptable plants that bring beauty — and food — to the ecosystem…

Before the high-tech gadgets used to track bird migration today, there was moon-watching: a technique dreamed up in the 1940s by ornithologist George Lowery. Using telescopes pointed at the moon to see the silhouettes of migratory birds, Lowery helped show that birds regularly migrate…

By late summer, most birds hatched in spring are on their own, without help from their parents. Where do they go? Young migratory birds will head south in late summer or fall, in the pattern of their species. But most non-migratory birds born last spring — such as this immature Bewick’s…

It’s been said that if someone knows only three birds, one of them will be the crow. They’re common, easy to see, and even easier to hear. But crow voices are complicated. Altogether, crows may use 30 sound elements in different combinations, and one of the most intriguing is their song…
