species distribution map JPG -- Species Photo

Gray tree frogs have the remarkable capacity to change their color from gray to brown or green within just a few minutes. They are medium-sized frogs that can grow to approximately two inches in length. Their toes are tipped with adhesive discs which enable them to climb and cling to smooth branches and leaves.

They are often seen on roadways hunting for insects on warm, humid, summer nights. During the day they prefer the shade and protection of trees and shrubs near water. Their diet consists mainly of insects.

They are found throughout the aspen woodlands of northeastern North Dakota.
