Frog Listeners 

Audubon wildlife biologist Susan Gallo says wood frogs and spring peepers are finally starting to make their spring mating calls, about two weeks later than normal because of the heavy snow cover and cold spring.

The conservation group is now looking for volunteers to participate in its annual Maine Amphibian Monitoring Project, now in its 12th year.

Participants are asked to go to designated spots in early and late spring and take notes of which frog species they hear. In the early spring, they’ll be hearing American toads and northern leopard and pickerel frogs, while in late spring they’ll hear gray tree, green, mink and bullfrogs.
