On a still winter afternoon, you may hear Common Goldeneyes flying low across the water. Whistlers, their wings sibilant, make the sound – as Ernest Hemingway wrote – of ripping silk. Common Goldeneyes nest in cavities, in northern boreal forests.

In the opening lines of Moby Dick, the narrator, Ishmael, confesses to "a damp, drizzly November in my soul." One sure way to brighten November's damp and drizzly mood is to welcome birds into your yard with bird feeders. Black-oil sunflower seed is especially popular. Hang suet in a wire…

University of Puget Sound professor and BirdNote science advisor Peter Hodum studies seabird conservation. And he says that if you can’t do something to address a problem, find someone who can.

Vampire Ground-Finches menace their victims in broad daylight, stabbing holes in their flesh, then devouring the blood. During the dry season, when their usual diet of seeds can be scarce, they turn to large seabirds, like boobies. Fluttering onto a booby’s back, the finch jabs its sharp…

In the UK for years, milk came in bottles with foil caps. Great Tits, a common songbird, learned how to peck through the foil. The skill spread. But how? Researchers trained Great Tits in different ways of opening a box and re-released them. Knowledge of how to open the box spread rapidly…

Related to shearwaters and petrels, the Northern Fulmar will eat just about anything it finds on the surface of the ocean, from fish and squids to dead whales. While some have snow-white bodies and gray wings, others are dark gray all over. That’s because fulmars are polymorphic, which is…

Despite their name, Prairie Warblers nest in tree farms of recently planted pines, in fields overgrown with scattered shrubs, and in clearings under power lines. Biologists call these “early successional” habitats. They’re characterized by plants that are the first to return to land…

Although we may think of autumn as the end of the growing season, a sort of winding down in the natural world, for birds it’s as much a season of renewal as the spring. In the colder months, we welcome back our winter birds — juncos, swans, and more — which spent the summer in their…

Sooty Terns have long been called "wide-awakes" because of their calls. But it may describe their sleeping habits, too. When young terns leave their breeding grounds, they don't return for several years. They do not rest on the water, and only rarely land on floating objects. They feed…

When you think of bird migrations, you might think of a bluebird or a robin first. But some owls do migrate – such as the Short-eared Owl, which flies south for the winter. Northern Saw-whet Owls were once thought non-migratory, but in fact they travel at night, unseen. Snowy Owls breed in…
