Because of its nearly 3,000 acres of tidal marsh, ponds and creeks, black ducks flock to the island located in Tangier Sound near the town of Crisfield. Other tidal wetland wildlife species are also attracted to the area, but its attraction for black ducks is legendary. In the 1960s, wildlife biologists became concerned about the black duck, which seemed to be declining in numbers. Loss of habitat was thought to be the primary cause. Today, black duck populations are on the mend and Cedar Island WMA is one of Maryland's best winter habitats for these beautiful birds.
