Maine Audubon Annual Loon Count set for July 16

FALMOUTH — For nearly four decades, Maine Audubon has been studying loon behavior and engaging volunteers across Maine in conservation efforts to bolster the loon population. One of its most powerful and popular tools is the Annual Loon Count, scheduled this year for Saturday, July 16, from 7-7:30 a.m. 

This event has engaged more than a thousand volunteers since 1983. On the third Saturday of July, participants head out in skiffs, kayaks and pontoon boats to tally the common loons they see. Last year, volunteers of all ages counted loons on 328 Maine lakes. 

Maine Audubon uses the statewide snapshot to estimate the annual population and track population trends across the decades. The information helps biologists, state officials and Maine lake users understand more about the loons’ status and the health of Maine’s lakes.  

“The count gives us a window into the status and changes in Maine’s common loon population over time,” said Tracy Hart, Maine Audubon wildlife ecologist.   

Since the loon count’s inception in 1983, the number of adult loons in the southern half of the state has essentially doubled, from an initial estimate of fewer than 1,500 to nearly 3,000 in 2020. This is thanks in part to conservation efforts like the Maine lead tackle ban and the Fish Lead Free Initiative ( thave helped reduce the number of adult loons that die from swallowing lead tackle.  

Last year, Maine Audubon received a five-year grant to expand the Maine Loon Project and to partner with Maine Lakes, Lakes Environmental Association and the Penobscot Indian Nation to work to improve loon productivity and reduce mortality in the state.  

The new partnership, the Loon Restoration Project, is an opportunity to work with local volunteers to start documenting loon nesting successes and failures in more depth. Key components include placing artificial nesting rafts where appropriate and creating a robust volunteer loon monitoring program.
