Bufflehead’s are smaller ducks with distinguishing white parts on their heads. The males have a large, white patch around back of head to cheeks, while the females have a white cheek spot. They are diving ducks, found in water areas such as lakes, ponds, or rivers. They eat insects, crustaceans, and plant life. Their range is where Northern Flickers are found, as they use their old nests for nesting cavities and breeding grounds.
