What are Spring Peepers?

Among the first frogs of spring is what Spring Peepers (Pseudacris crucifer) are in Canada and the eastern United States of America.

Specifically, Spring Peepers may range in color from straw to rusty orange, olive, gray or brown. They tend to have dark bands around their hind legs and a dark line that runs from eye to eye in addition to the characteristic dark "X" across their backs. They have well-developed toe pads which help get them along the ground, around small bushes and through breeding ponds. But what they are most known for are their aggressive "purrrreeeek" and their pure-tone "peep" calls in spring, late summer and fall.
