Distinguishing Features - The tiniest of all frog species in Northwestern Ontario. Overall colouration, varying shades of brown, gray, olive or reddish with three relatively wide, brown, rusty or greenish stripes down the length of the back (may be broken). Underside, plain light brown. A stripe runs horizontally from the snout through the nostril and eye and continues down the side to the groin. Body, long and slender compared to the short legs. Toe pads, tiny.

Boreal Chorus Frog Size -
2.54 cm (1 in)

Habitat

Found throughout the southern regions of Northwestern Ontario in a variety of habitats, but never far from woodlands, in temporary pools of water to large wetlands and even in lake shallows.

Breeding

Breeding activity begins shortly after the thaw and is done by the end of May. Chorus frogs lay small clusters of eggs. The tadpoles metamorphose in about 2 to 2-1/2 months.

Notes

Borel chorus frogs feed on small invertebrates which they hunt in low shrubs.

Chorus frogs overwinter under rocks or logs.

Their call sounds like a pprrreeep, vey much like running a thumbnail down the teeth of a fine toothed comb.
