Description: The Mountain Chorus Frog is a small
(1-1.5 in; 25-38 mm) gray to olive frog with a marking on the
back that resembles a reverse parentheses. Occasionally the
parentheses will touch in the middle forming an X on the back.
This is similar to the pattern of the Spring Peeper (Pseudacris
crucifer); however, the Mountain Chorus Frog usually can be
identified by a dark triangle between the eyes that the Peeper
lacks. The Mountain Chorus Frog also has a white line on the
upper lip as is typical of chorus frogs. Yellow flash colors
can be observed on the concealed portions and the underside of
the leg. In our region the range of this species is extremely
limited (north Georgia mountains) and range along is often sufficient
to eliminate this species when trying to identify an unknown frog.
Range and Habitat: Mountain Chorus Frogs are found in
two disjunct populations, one in the central Appalachian Mountains
(West Virginia, Kentucky, Ohio, and Pennsylvania) and one in central
and northern Alabama. In our region this species is only found
in a small section of the north Georgia Mountains. This species
can be found in woodlands and forested areas, usually on hillsides
at elevations of 3500 feet or higher. Shallow bodies of water
are its preferred breeding sites, including spring and stream
pools and ditches.
Habits: Little is known about the ecology of this secretive
species. They are most often observed when they congregate at
woodland pools in the early spring (March - May) to breed. Males
call from open areas during both day and night. Tadpoles are small
and take 40 - 65 days to mature. Adults are seldom seen in summer
months and presumably reside in leaf litter and eat a variety
of small invertebrates.
Call: The call of Chorus Frogs has been likened to the
sound that a comb makes when a finger is run down the bristles.
Pseudacris brachyphona's call is more rapid, high-pitched,
and nasal sounding than that of the similar upland chorus frog
Conservation Status: Although little is known about this
species in our region, it is thought to be declining in other
parts of its range.
