Description - The refuge serves as a nesting, feeding, resting and staging areas for migratory waterfowl. The varied habitats support approximately 266 species of birds, 42 species of mammals, plus reptiles, fish, amphibians and insects. Bald eagles have maintained an active nest on the refuge since 1986. Management goals address the needs of species of special concern including black tern, black ducks, osprey, American woodcock, and peregrine falcons which use the refuge during some time of the year.
- The relatively flat terrain encompasses 10,818 acres of habitat. The boundary of the refuge goes all the way to Salt Works Road on the west, Rout 77 and Casey Road and Roberts Road to the south (except for private in-holdings. Freshwater marshes and hardwood swamps border or are fed by Oak Orchard Creek which enters the refuge from the east and meanders in a westerly direction before leaving the refuge at the north boundary to empty into Lake Ontario 20 miles away. Forests, meadows and fields slope up gently from the wetland's edge.
The refuge is located in an area known as the Oak Orchard Swamp, locally known as "the Alabama Swamp". The Seneca Indians, one of the six tribes of the Iroquois Nation and the aboriginal inhabitants of this area, were the first to farm the area by clearing garden plots within the oak forests near their villages. To the first European settlers in the late 1700's the remaining clusters of oak trees resembled orchards. Thus the name, "Oak Orchard Swamp".
