These two species are distinguishable based on variation in their calls. The gray treefrog is common to the northeast but has a distribution ranging from Texas across to northern Florida and up to Maine and New Brunswick.
They prefer wooded habitats with trees and shrubs near to water sources. Appearance: The gray treefrog varies in color from greenish-gray to gray-black depending on their background environment. They may have a light-colored spot underneath the eyes and their skin may have a bumpy texture. Gray treefrogs have a yellowish patch on the ventral side of their back legs which might only be visible when jumping or moving.
These frogs are expert at camouflage and may have a mottled pattern resembling lichens, although they tend to be more greenish during the breeding season. The upper surfaces of the legs feature a dark, banded pattern, which contrasts starkly with the bright yellow or orange undersides of the legs. Scientists believe the bright coloration serves as a warning for predators not to attack. The gray tree frog has webbed hands and feet. The enlarged tip of each digit produces an adhesive fluid that allows this species to better grip trees and improves its climbing abilities.
The frog's belly is white, although the male reveals a black throat when it is calling. Like the adult, the gray tree frog tadpole has inconsistent coloring, including different shades of brown or olive green. As tadpoles, they are scarlet or orange-vermilion with black blotches around the edge of the crests. The body and tail are patterned with many specks of black and gold. As the individual ages, it develops its adult coloration.
Adult male gray tree frogs are around 1. Females are typically slightly larger than males, ranging from 1. The gray tree frog's range covers much of the eastern United States, from northern Florida to central Texas and north to parts of southeastern Canada. It is a largely arboreal species that occupies a variety of wooded habitats and is frequently found in forests, swamps, on agricultural lands and in backyards. Access to trees and a water source is common to all habitats it occupies. When a gray tree frog is young and newly metamorphosed, it usually remains near the forest floor.
As it ages, it may transition to living in the forest canopy. Males emit a loud, musical call, usually after dusk, for as long as four hours.
The male uses the call to establish a breeding territory and to find a mate. Adult gray tree frogs mainly prey upon different types of insects and their own larvae. Mites, spiders, plant lice, snails and slugs are common prey. They may also occasionally eat smaller frogs, including other tree frogs. They are nocturnal and hunt in the understory of wooded areas in trees and shrubs. As tadpoles, they eat algae and organic detritus found in the water. A male begins the mating call in early spring, shortly after emerging from hibernation.
