Updated Distribution Map
Gray treefrogs are rarely found out of the treetops except during breeding season. They often create large choruses in shrub swamps, flooded hayfields, wet meadows and shallow marshes. Their loud, loose trills are heard in mid-spring. Large choruses can make it difficult to hear other calling amphibians using the same areas. Outside of the breeding season gray treefrogs can occasionally be heard vocalizing from treetops before or after thunderstorms.
