Gray Tree Frog

Hyla versicolor
Though the common name identifies this species as the Gray Tree Frog, the scientific name is a bit more accurate. Hyla versicolor alludes to the fact that these frogs can actually change color- their skin can slowly change to match their surroundings, moving from gray to green to white to brown to black! They also sport some vibrant yellow patches under their hind legs, though they are difficult to see unless the frogs are in mid-leap.

Gray Tree Frogs can be found in the eastern United States and in southern Canada. They are relatively small compared to other species in that range. As their name suggests, they live up in the trees. Breeding is pretty much the only activity that motivates them to leave their tree.

If you live in their range, you may have heard their calls! On warm nights during the breeding season the males produce very loud buzzing trills. These calls are made while the males are hiding in vegetation near bodies of water. Females are attracted to these sounds, will enter a male's territory, mate, and then lay her eggs in the nearby water. Calling rarely occurs outside of the breeding season.

IUCN Status : Least Concern
Location : North America
Size : Body length up to 2in (5cm)
Classification : Phylum : Chordata -- Class : Amphibia -- Order : Anura
Family : Hylidae -- Genus : Hyla Species : H. versicolor

  1. Up to the point where i read that it can actually change its color, I was thinking why they call it GREY, since on the picture we can clearly see that it is green haha
