Field Notes
Description:
The mountain chorus frog is a small frog, but an intermediate size for the genus Pseudacris. It is colored different shades of grey or brown, including sorghum brown, deep brownish-drab, or mars brown. 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 adult frog grows from 1.0 to 1.4 in long. The males are usually between 24 and 32 mm and the females between 27 and 34 mm. The mountain chorus frog has a unique triangle between the eyes and a white line on the upper lip; the male uniquely has a dark throat.
Habitat:
The mountain chorus frog can usually be found on the hillsides of southwestern Pennsylvania, Western Maryland, southeastern Ohio, eastern Kentucky, West Virginia, northern Alabama, northern Mississippi, and Tennessee. They live on springy hillsides, grassy pools, and ditches, typically distant from water. The wooded hillsides where the frogs live are up to 3,500 feet in elevation.
Notes:
The mountain chorus frog has a unique call. It is a faster, higher note, and holds a distinct quality and form. The repetitions are quicker and the pitch higher. When a whole chorus of them are heard, one can tell them apart from other groups. The Mountain chorus frog's call has a rate of 50 to 70 times a minute and can be continued for several minutes, though they usually stop in 15 to 20 seconds. This distinct call is rapid and can be heard on a clear night up to a quarter mile away. Their voice has a bit of a nasal quality to it and sounds like a wagon wheel turning that needs oil. It is a harsh, raspy "wreeck" or "reek" sound.
