The Bufflehead is a small species of duck that lives across much of North America. They breed across much of Canada and spend the winter further south, from the West Coast of the US through the Rockies and the Great Plains and parts of the southeast. They also winter in parts of Mexico and the Caribbean.
Buffleheads are cavity nesters, using tree cavities, often created by Northern Flicker woodpeckers, or nest boxes, for breeding.
Buffleheads are diving ducks, meaning that they dive under the water when feeding. They feed in freshwater or saltwater, dining on different prey depending on the type of water.
