Gray Tree Frogs (Hyla versicolor) are found across eastern North America. You’ll spot them in a wide variety of wooded habitats, from backyards to forests to swamps.

But the BEST way to locate one is to listen! Once you know what to listen for, they are easy to identify by sound.

Their mating calls sound like a loud, musical, bird-like trill.

Calls typically last about half a second and are repeated every few seconds. Males sing for up to FOUR hours straight when trying to find a mate!

The BEST time to hear a male Gray Tree Frog calling is at night, but they can be heard randomly at any time of day.

Calls are heard during spring and summer when males are trying to find a mate and establish a territory.

You can find Gray Tree Frogs in wooded habitats that are near water, from backyards to forests to swamps. We have even found them on the outside of our windows at night!

This incredible tree frog can slowly change colors to match what it's sitting on, just like a chameleon. Despite their name, they vary from gray to green to brown.

Adults are 1.25 - 2.25 inches (3.2 - 5.7 cm) long. Look for a whitish patch beneath each eye.
