Oyster Bay has the greatest winter waterfowl use of any of the Long Island national wildlife refuges. The numbers of waterfowl using Oyster Bay are lowest from May through August, and start to increase in September and October. Puddle ducks such as black ducks, gadwall, and mallards start migrating to the refuge in early autumn, and their diversity begins to increase in November. Waterfowl numbers peak and remain high from December through March, then decline in April.
