Upland Chorus Frog

Pseudacris triseriata

Upland Chorus Frog

Description - Body 3/4 - 1 3/8 inches (1.9 - 3.5 cm). Coloration varies from pale gray to olive brown. The Chorus Frog has a white line on the upper lip and a dark stripe from the snout, through the eye and onto the side of the groin. Stripes or spots can often be seen along the back of the frog.

Voice - Males call from perches on floating vegetation. The call is a vibrant regularly repeated series of "crreeks" or "prreeps". It is often compared to running your fingers over the teeth of a small pocket comb or the sound of a ratchet being moved back and fourth. The call is more rapid as temperatures increase. Calls can be heard during cooler weather.

Habitat - This frog prefers moist grasslands and damp forests. It can most often be found around prairie ponds.

Breeding - Breeding takes place January - April. It is strictly a cool weather breeder which has distinct advantages in that it does not have to worry about cold-blooded predators such as snakes, which are not active in cool temperatures.

Range in Texas - The Upland Chorus Frog can be found in most of East Texas as far south as Corpus Christi.

Notes- This frog is strictly nocturnal and disappears under water or vegetation when approached.
