Family: Hylidae, Treefrogs view all from this family

Description 1 1/4-2 3/8" (3.2-6 cm). Skin rough; greenish or brownish to gray, with several large dark blotches on back. Dark-edged light spot beneath eye. Under surfaces of thighs bright yellow-orange. Large toe pads.

Voice   A hearty, resonating trill, usually heard in spring and early summer.

Breeding April to August. Also breeds in winter in southern parts of range.

Habitat Trees and shrubs growing in or near permanent water.

Range From s. Ontario and Maine to n. Florida west to c. Texas, north through Oklahoma to Manitoba.

Discussion There are two species of Gray Treefrog that are identical in appearance, and since their ranges overlap extensively, they cannot be distinguished in the field. However, Cope's Treefrog (H. chrysoscelis) has a faster trill and only half as many chromosomes as the Gray. Nocturnal; they live high in trees and descend only at night, usually just to chorus and to breed.
