Bufflehead Duck Houses

In most areas Buffleheads start nesting soon after their arrival. The female Bufflehead lays her eggs in a tree cavity, usually the former nest of a Flicker (woodpecker). The related goldeneyes and mergansers are also tree-nesters, and some people refer to any duck nesting in a tree as a "wood duck." The true Wood Duck, however, is not closely related to the tree-nesting diving ducks. The Bufflehead is the only tree-nesting duck that can use nest holes of Flickers, the other ducks needing larger cavities.
