The Eastern Gray Tree Frog is a common tree frog found along the eastern United States and Canada. The Eastern Gray Tree Frog is not always gray, it can also be green because they change their color based on their environment. The Eastern Gray Tree Frog is identical to the Cope’s Gray Tree Frog except for the call and the number of chromosomes.

The time period for breeding varies depending on latitude, with the lower latitudes breeding in early spring while higher latitudes breed later into summer.  The breeding period is the only time you will see the Gray Tree Frogs on the ground, otherwise, they are up in the trees. Males will come down from the trees and start calling in shallow water. Females arrive after the calling to mate.  The females lay their eggs in the shallow water,  near vegetation on the surface. It takes around 2 months for the eggs to complete metamorphosis.
