Maine Audubon is looking for volunteers across the state to listen for and note frogs on several evenings through early summer.

Volunteers will conduct two-hour roadside surveys, making 10 stops along their route and waiting five minutes at each to note frog species.

Volunteers should have email and internet access and be able to commit three years to the project. They must pass an online quiz on frog calls.

For information contact Susan Gallo at 781-2330 ext. 216 or sgallo@maineaudubon.org.
