About the Boreal Chorus Frog

The boreal chorus frog (Pseudacris maculata) is a species of chorus frog native to Canada from central Quebec to eastern British Columbia and north to the Northwest Territories and the southern portion of the Yukon. It occurs in the USA throughout Montana, Minnesota, northwestern Wisconsin, northeastern Arizona, northern New Mexico, and southwestern Utah.

This small species of frog reaches about 30 mm in length. It is highly variable, but is normally brown, and can be green on the dorsal surface, with three broken dorsal stripes; these stripes can be very distinct to quite faint. A dark band is present from the snout, across the eye, and continuing down the side. It has slightly enlarged toe pads to help in climbing small grasses and vegetation. This species is very similar to the western chorus frog (Pseudacris triseriata). It can be distinguished from this species by having shorter legs.

This species can be found around permanent water bodies in cleared land and forest. Males make a "reeeek" call from grasses, vegetation, or ground around the water body from April through to September. This call is characteristic of the trilling frog clade... Wikipedia →
