Most gray squirrels look silvery gray with brownish markings on their tails.
Hunters also killed them because of their uniqueness. Gray squirrels mostly eat acorns, hickory nuts, walnuts, beech nuts, berries, mushrooms, pine seeds, corn, dogwood, and wild cherry and black gum fruits. A life span for the gray squirrel is about 10 years or longer but few live longer than two or three years. Tree dens are often found in cavities where small branches have fallen off or in empty woodpecker holes about 40-60 feet high. Gray squirrels often have a first litter in February or March and a second set of young in July or August.
