The Grey Tree Frog is also known as the Gray Tree Frog and the North American common tree frog. Its scientific name is Hyla versicolor. The Grey Tree Frog belongs to the genus Hyla in the family Hylidae and is a close relative of Cope's Grey Tree Frog (Hyla chrysoscelis) and the American Green Tree Frog (Hyla cinerea). The Grey Tree Frog is a common pet that is easy to care for if you provide it with a suitable vivarium. Plants, branches and suitable hiding spots are naturally also necessary if you want to house a Gray tree frog. 

Gray tree frog – range
Gray tree frogs inhabit a significant part of the North American continent. In Canada, their range includes the provinces of Ontario and Manitoba, and you can also find an isolated Grey tree frog population in New Brunswick. In the United States, Gray tree frogs are present in suitable habitats in most of the eastern half of the country. The range proceeds as far west as central Texas.

Gray tree frog – description
Gray Tree Frogs tend to stay around 1.5-2 inches (4-5 centimetres) in length, which is quite small compared to most other North American frog species. The Gray Tree Frog is aptly named, since their main body colour is grey. The skin looks a bit warty and the exact gray shade can vary from pale gray to a darker gray shade. The Gray Tree Frog can also display green, yellow, black or dark grey mottling. On the hind legs of the Gray Tree Frog you can see patches of bright orange. A male Gray Tree Frog will display a black or dark grey throat, while the female throat is comparatively pale. Distinguishing the Grey Tree Frog (Hyla versicolor) from its close relative the Cope's Grey Tree Frog (Hyla chrysoscelis) is extremely difficult as long as the animals stay silent. Their call is the only easily detectable difference. 

Gray tree frog – habits
The Gray tree frog spends most of its time up in trees. They will typically choose a habitat where trees can be found growing not too far from a permanent body of still water. When the rain creates shallow temporary puddles of water you can often see (or hear) Gray tree frogs gather around them. The Gray tree frog feed on insects and will typically hunt only during the night. Theire staple food in the wild are small arthropods.

Gray tree frog – temperature
The Gray tree frogs are surprisingly hardy when it comes to temperature. The preferred day time temperature is 68°-78° F (20°-26° C), but the Gray tree frog is known to survive a temperature drop down to 50° F (10° C) is long as the low temperature does not persist. Gray tree frogs can also survive temperatures up to 90° F (32° C) for shorter periods of time. Such extreme temperatures should however naturally be avoided if you keep Gray Tree Frogs in captivity. They will benefit from a slight decrease in temperature during the night, but not down to 50° F (10° C).
