12 facts about gray tree frogs

There are over 800 known species of tree frogs in the world, and only a handful of those are found in the United States. The following list of tree frog facts are just about the gray tree frog.

1. There are no recognized subspecies of gray tree frogs

Gray tree frogs are often referred to as eastern gray treefrogs, northern gray treefrogs, common gray treefrogs, or tetraploid gray treefrog however these are all the same species. There are no known subspecies of the gray tree frog.

2. Gray tree frogs can change from almost black to almost white in color

Even though these frogs are usually gray, brown, or green, they have amazing color-changing skills. They change colors much slower than a chameleon can, but the ability to blend in and hide is their number one defense against predators.

3. Gray tree frogs look almost identical to Cope’s gray tree frogs

You can tell them apart only by their calls. The Cope’s gray tree frog has shorter call and also a faster pulse, neither of which you can tell by just looking a them. The common gray tree frog also has 48 chromosomes, twice as many as the Cope’s gray tree frog.

4. They have a wide range from Texas to the east coast

Gray tree frogs are found from Central Texas north to Western Minnesota, then east all the way to the coast. Though they do not occur in southern parts of Florida or in Northern Maine. They’re one of the most common tree frogs in the eastern half of the United States.

5. Gray tree frogs eat a variety of small insects and invertebrates

Because of their small size, gray tree frogs feed primarily on small insects and other invertebrates. They most often eat flies, ants, crickets, beetles, moths, and snails or slugs. As tadpoles they are herbivores. Gray tree frogs often gather by porch lights at night to catch insects.

6. Like many other types of frogs, gray tree frogs can secrete a poison

Females can lay up to 2000 eggs in batches of 20-40 eggs each. They will usually lay these eggs in small ponds and still water that does not have fish. The eggs will be tadpoles in 4-5 days which will be frogs in just 2 months.

8. Adults are often cannibalistic

They start out as herbivores when they are tadpoles. Though they are mostly insectivores as adults, they will also eat smaller frogs including other tree frogs or even their own eggs and tadpoles.

9. Gray tree frogs are small and only reach about 2 inches in length

Gray tree frogs are very small and only reach 2.5 inches maximum as adults, but often closer to 1.5-2 inches in length. This only aids them in trying to remain incognito and hidden from the world until nightfall when they come out.

10. Gray tree frogs are nocturnal

Gray tree frogs remain hidden and still, usually high up in the trees during the day. At night time though they come down and the male’s call can be heard starting at dusk. This is also when they commonly look for insects and food.

11. The male’s call can travel for a third of a mile

You can hear the male gray tree frogs call from a third of a mile away and the sound up close can reach 108 decibels, that’s as loud as a lawnmower.

12. Gray tree frogs are solitary animals

They congregate in the spring during breeding season, but other than that gray tree frogs are solitary animals that live their lives alone.
