Upland Chorus Frog
Pseudacris feriarum
Summary 5
The upland chorus frog (Pseudacris feriarum) is a species of chorus frog found in the United States. It was recently separated from the Western chorus frog, (Pseudacris triseriata), being identified as an individual species rather than a subspecies. The upland chorus frog is generally brown and gray.
Physical Description 6
The visual feature that distinguishes this frog from the Western chorus frog is a dark triangle that is present between the eyes on the back of the head. There are three dark spots present on the body of the Upland Chorus frog. There are on the middle of the back, the snout to tailbone and on the eyes. The bottom side or underside of the frog has spots and is off-white. This species ranges in size from 19 to 35 mm (3/4 to 1-3/8 in). Its dorsal pattern is extremely variable with a few consistencies, a light line along the upper lip, a dark stripe from snout to groin that passes through the eye. The general coloration is brown or grey. The middorsal pattern may be striped, partially striped, spotted or absent. Typically there are 3 long dark stripes that may be broken into streaks or rows of small spots. A dark triangle is often present between the eyes. The ventrum is cream-colored and often stippled with dark spots. The tibia length is equivalent to 1/2 the length from snout to vent.
Reproduction 6
The normal breeding period for this species is usually between February and May. The male mating call is a regularly repeated "crreek" or "prreep" resembling the sound of running a finger along a comb. The frog reaches sexual maturity after one year. After mating is complete, there are approximately 1,000 eggs laid onto vegetation along wet areas. Metamorphosis occurs in two or three months.
Habitat 7
This species of frog is usually found in lentic waters, i.e. (floodplains, meadows, and swamps). They are found throughout the coastal plain and the piedmont regions.
Behavior 8
They are found among grassy swales, moist woodlands, river bottom swamps, and in the vicinity of ponds, bogs, and marshes. Silent males exhibit a behavior called sexual interference or satellite behavior. These satellite males sit quietly near calling males.
