Cope's Gray Tree Frog, Hyla chrysoscelis, is a species of tree frog found in the southeastern United States. The frog is named for Edward Drinker Cope who first described it in 1880.

Nearly indistinguishable from the Gray Tree Frog, Cope's variety has a faster and higher-pitched call. Both species have bright yellow or orange coloration on their inner thighs, which is visible when they jump!

These frogs spend most of the year high in the trees of mature deciduous forests. In early summer, they migrate to ponds for the mating season. This is when you are most likely to hear their calls.

Even though they are most often gray as adults, young Cope's Gray Tree Frogs are typically green!
