Volunteers needed

FALMOUTH – Maine Audubon seeks volunteers to listen for and note the sounds of frogs along specific roadside routes on several evenings from early spring through summer for the Maine Amphibian Monitoring Project.

“Citizen science” volunteers are needed for roadside routes in Advent Swamp (west of Bridgewater, DeLorme Maine Atlas Map 59), Bridgewater, Caucomgomac Lake, Dedham, Ellsworth, Monroe Center, Musquacook Lake I (T11 R11 WELS), Patten, Pittston Farm (Pittston Academy Grant, DeLorme Maine Atlas Map 48) and Springfield.

Volunteers conduct surveys first in early spring to hear spring peepers and wood frogs, then in late spring to hear American toads and northern leopard and pickerel frogs, and finally in early summer for gray tree, green, mink and bullfrogs. They make 10 stops along their routes, waiting five minutes at each stop and noting the frog species they hear. Volunteers should be able to make a three-year commitment to the monitoring project. Prior knowledge of frog calls is helpful, but training material as well as an audio quiz is available at www.pwrc.usgs.gov/naamp.

Those interested should contact Susan Gallo at 781-2330, ext. 216, or sgallo@maineaudubon.org.
