Bufflehead


We saw this female beauty at Lake Lurleen State Park. The 6 dollar entrance fee was well worth it to witness this duck! 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.

The Bufflehead nests almost exclusively in holes excavated by Northern Flickers and, on occasion, by Pileated Woodpeckers. Unlike most ducks, the Bufflehead is mostly monogamous, often remaining with the same mate for several years. Bufflehead fossils from the late Pleistocene (about 500,000 years ago) have been found in Alaska, California, Florida, Illinois, Kansas, Texas, and Washington. One California fossil that resembles a modern Bufflehead dates to the late Pliocene, two million years ago. The oldest Bufflehead on record was at least 18 years and 8 months old. It was caught and re-released by a bird bander in New York in 1975.
