Ermine records in Maine reach 14 of the state’s 16 counties, from York on the southern coast to Aroostook at the state’s northern tip. Cumberland County, around Portland, leads with 13, Penobscot follows with 11, and no single named site holds more than one record.
The coast as much as the deep woods
The coast carries real weight. Besides Cumberland, Hancock County on the Down East shore holds 8, and York, Lincoln, and Knox add more along the southern coast and midcoast. Coastal Maine gives an ermine much of what the interior does: rodent-rich edges, old stone walls, brushy fields, and marsh margins where dense cover sits right beside open hunting ground. That broad spread fits a small hunter that follows voles and mice wherever they’re thick, rather than one tied to a single kind of forest.
Brown in spring, white in winter
Reports peak in May, with 12, hold at a steady handful through summer and fall, and thin out in January and February. By May, Maine’s ermine have molted back to summer brown and people are back on the trails and in their yards. Winter is when the white coat with its black tail tip shows, and a white weasel darting along a snowy stone wall still catches attention, but the snow months hold fewer reports than the warm ones.
The ermine is native to Maine. By record count it sits 34th of 85 mammals in the state, a fair showing for an animal that spends so much of its life inside rodent tunnels.
