Gray Tree Frog (Hyla versicolor) is a member of the tree frog family, Hylidee. They live in the eastern side of the United States and Canada. They are adapted to surviving freezing conditions. They are a small frog species, only growing up to 2 inches. Males have gray / black throats while females have white throats. Gray Tree Frogs can be green or gray depending on what substrate they are on.
Gray Tree Frogs are easily confused with Cope’s Gray Tree Frogs (Hyla chrysoscelis). The only differences is the calls of the 2 frogs and that Gray Tree Frogs have an extra set of chromosomes than the Cope’s Gray Tree Frog. Cope’s Gray Tree frog and Gray Tree frog can be identified from other tree frogs because they have yellow on the bottom hind legs.
