This large, slate grey tree squirrel (Sciurus niger cinereus) has an unusually full, fluffy tail and white belly. Larger than common gray squirrels, some fox squirrel subspecies measure up to 30 inches long and weigh up to three pounds. Once found throughout the Delmarva Peninsula, remnant populations of the Delmarva fox squirrel now persist naturally only in portions of Queen Anne's, Talbot and Dorchester Counties in Maryland. Translocated populations now exist in other areas of Maryland, Virginia, Delaware and a small area in Chester County, Pennsylvania. The fox squirrel is found mostly in mixed stands of mature (acorn-producing) hardwoods and mature loblolly pines. Other areas include groves of trees along streams and bays, small woodlots in agricultural fields and forest near salt marshes. This squirrel is an endangered species.
