Cardinals in, boreal chickadees out: new atlas shows changing bird populations in a warmer Maine

MAINE PUBLIC • February 14, 2022

Forty years ago, Maine wildlife officials and local birders joined up to create the first Atlas of Breeding Birds in Maine. The five-year survey documented the range of avian species nesting and raising their chicks here. Now, the first comprehensive follow-up is nearing completion, and it indicates that since the early 1980s, the complex interplay of global warming, habitat shifts and other factors have brought significant change in the types of birds that are at home in Maine.
