the Western Chorus Frog
(Pseudacris triseriata)

Listen to its Call:
A short, rising "cree-ee-ee-eek" which has been compared to the sound made by running a finger over the fine teeth of a pocket comb.

Size: 1.9-3.9 cm in length (0.75-1.5 inches)

Coloring:
Brown, reddish, or tan to gray or olive; the belly is creamy or white, sometimes with dark spots on the throat and chest; a distinctive white or cream-colored stripe runs along the upper lip, bordered above by a dark brown stripe running through the eye from nostril to the groin; three dark stripes usually run down the back.

Habitat:
Generally lives in marshes, meadows and other open habitats, though it may be found in damp woods or wooded swamps; found throughout the Great Lakes region except in east-central Ontario and Michigan's Upper Peninsula.

Confusing Species:
The Spring Peeper lacks the distinct white upper lip line and usually has an X-shaped marking instead of lengthwise striping on the back. Blanchard's Cricket Frog is wartier and also lacks the white lip stripe and dark back stripes. Small Wood Frogs have dorsolateral folds -- ridges of skin that run down each side of their back.

Breeding: Mid-March into late May

FACT: Its loud call, combined with a distinctive dark stripe that runs from the snout through its eye and along its body, make the Western Chorus Frog easy to identify. You might have a hard time spotting one, however, because these frogs rely on secrecy to protect themselves from their enemies. Any disturbance will cause these frogs to stop calling and dive to the pond bottom, where they will hide in the mud until the danger has passed.
