[citation needed] The Collinses' mountain chorus frog (Pseudacris collinsorum), which ranges from southwestern North Carolina/southeastern Tennessee south to most of Alabama aside from the north and west to northeastern Mississippi, was formerly thought to represent a population of P. brachyphona, but was described as a distinct species in 2020.

The almost 500 species of tree frogs are found all over the world, from tropical regions to the Canadian woods, and Australia.

It is stocky in the body and broader in the head, which is very close to the structure and size of H. femoralis, the pine woods tree frog.

The Appalachian mountain chorus frog has a triangle between the eyes and a white line on the upper lip; the male has a dark throat.

The Appalachian mountain chorus frog can usually be found on the hillsides of southwestern Pennsylvania, western Maryland, southeastern Ohio, eastern Kentucky, West Virginia, eastern Tennessee, and northern Alabama north of the Tennessee River.

They live on springy hillsides, grassy pools, and ditches, typically distant from water.

[4] Their voice has a bit of a nasal quality to it and sounds like a wagon wheel turning that needs oil.

[5] The Collinses' mountain chorus frog has a similar call but with a faster pulse rate.

If the frog lives near the base of a hill, it will lay eggs in ditches, pools along streams, or springs.
