Loons are on the mend in Maine, filling more of the state’s lakes and ponds with their haunting calls, although conservationists say the birds aren’t out of the woods yet.
Maine is home to a few thousand of the distinctive black-and-white waterbirds — the East Coast’s largest loon population — and conservationists said efforts to protect them from threats helped grow the population. An annual count of common loons found more adults and chicks this year than last, Maine Audubon said this week.
The group said it estimated a population for the southern half of Maine of 3,174 adult loons and 568 chicks. Audubon bases its count on the southern portion of Maine because there are enough bird counters to get a reliable number. The count is more than twice the number when they started counting in 1983, and the count of adults has increased 13% from 10 years ago.
“We’re cautiously optimistic after seeing two years of growing chick numbers,” said Maine Audubon wildlife ecologist Tracy Hart. “But it will take several more years before we know if that is a real upward trend, or just two really good years.”
Maine lawmakers have attempted to grow the population of the loons with bans on lead fishing tackle that the birds sometimes accidentally swallow. Laws that limit boat speeds have also helped because they prevent boat wakes from washing out nests, conservation groups say.
