A buoyant, large-headed duck that abruptly vanishes and resurfaces as it feeds, the tiny Bufflehead spends winters bobbing in bays, estuaries, reservoirs, and lakes. Males are striking black-and white from a distance. A closer look at the head shows glossy green and purple setting off the striking white patch. Females are a subdued gray-brown with a neat white patch on the cheek. Bufflehead nest in old woodpecker holes, particularly those made by Northern Flickers, in the forests of northern North America.More ID Info
During the winter, look for these tiny, black-and-white ducks in sheltered coves along the Atlantic or Pacific coast, or on inland ponds in southern North America. While foraging they spend half their time underwater, so scan carefully and patiently. In the summer you can visit their breeding grounds near lakes in the boreal forest and aspen parklands of central Canada.
Bufflehead will take up residence in nest boxes during the summer in forested areas of central and western Canada. Consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Bufflehead are more likely to choose a small box (6 x 6 x 15 inches) with a 2.5-inch-diameter opening than a large box (7 x 7 x 15 inches or bigger) with a larger opening.
