Quissett Harbor is another terrific location to watch wintering ducks. One of the most frequent wintering ducks is the Bufflehead. The bufflehead is a small diving duck and is commonly found in sheltered bays and coastal harbors. The bufflehead has a mostly white body, black back, large dark head with greenish-purple gloss and a large white wedge on back of the head. This Bufflehead was in a large flock in Quissett Harbor and took flight in beautiful light.
