The Annual Loon Count

Will you join us?

Loon Count 35th Anniversary LogoOn the morning of the third Saturday of July each year, over 1,000 volunteers venture onto lakes and ponds across the state to count loons. The observations recorded by our community scientist volunteers provide an excellent “snapshot” of Maine’s loon population. Contact us at to learn more about getting involved.

The 2022 Loon Count will take place on Saturday, July 16

Following the 2021 count, Maine Audubon estimated a population of 3,446 adult Common Loons and 224 chicks for the southern half of Maine. (Each year, our estimate is for Maine south of the 45th parallel — roughly south of a line from Rangeley to Calais — which is the area where we have enough lakes covered by counters to make a reliable estimate.)

For more than 38 years, citizen scientists have helped us collect invaluable data to chart the status of our loon population over time. Open this interactive map to review Loon Count results on lakes across Maine from 1983 through 2020.
