A tube of black oil sunflower seeds isn’t “natural”…and neither is a suet cake. Yet as soon as you hang them up, the neighborhood birds, like these female finches, find them. Those grosbeaks at your feeder probably never ate sunflower seeds in nature. Sunflowers grow in open plains, while…

Around this time of year, Common Mergansers cross the US-Canadian border on their way to wintering grounds in the Lower 48. But how do they know when to go? Ducks are well insulated against frigid winter temperatures, but mergansers can find their fishy prey only by diving below the…

The Cuban Tody is almost indescribably cute! It’s a "must-see" bird for anyone heading for the West Indies. In woodlands throughout the island of Cuba, todies are terrific foragers. In fact, their Puerto Rican cousins have been known to catch up to one or two insects a minute — hunting…

Sapsuckers drill small holes in the bark of favored trees, then return again and again to eat the sap that flows out. And hummingbirds, kinglets, and warblers come to the sap wells to eat the insects trapped in the sap. Although a sapsucker - like this Red-breasted Sapsucker - may suck a…

The dense cover of coastal chaparral supports many birds found nowhere else in the world, including this California Thrasher. The plant species are different, but the chaparral of California is much like shrubby coastal vegetation in southern Europe, South Africa, southern Australia, and…

It's mid-winter, and a passing flock of robins suddenly drops out of the sky. A moment ago, the yard was empty of birds, but now it's full. They settle in a bush laden with fruits (like this hawthorne). When the robins pass over a fruiting shrub, those red berries signal like a neon sign…
