Boreal chorus frog pseudacris maculata
Description
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.
Ecology and behaviour
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 is normally one of the first species of amphibian to emerge in spring, it is often found while snow and ice are still present.
