When squirrel are recorded in Maine

Maine is home to three main squirrel species: the Eastern gray squirrel, the American red squirrel, and the Northern flying squirrel. Each occupies different habitats and shows distinct field marks. This guide will help you identify them and know where to look for the best sightings.

1. What types of squirrels live in Maine?

Maine has three resident squirrel species. The Eastern gray squirrel (Sciurus carolinensis) is common in towns and hardwood forests. The American red squirrel (Tamiasciurus hudsonicus) favors coniferous areas. The Northern flying squirrel (Glaucomys sabrinus) is nocturnal and lives in mature forests. A fourth, the Southern flying squirrel, is rare and only found in the southernmost counties. For a broader overview of Maine wildlife, see ourMaine wildlife hub.

2. How can you tell Eastern gray squirrels and red squirrels apart?

Eastern gray squirrels are larger (17-20 inches) with gray fur and a white belly. Red squirrels are smaller (11-14 inches), reddish-brown with a white belly, and have a distinctive white eye ring. In winter, red squirrels develop ear tufts. Gray squirrels often have a bushy tail that they hold over their back; red squirrels keep their tail flat. For more on squirrel identification, visit oursquirrel species page.

3. Where in Maine are you most likely to see each species?

Eastern gray squirrels are everywhere in southern and central Maine, especially in parks and suburbs. Red squirrels prefer northern and western forests (like Baxter State Park and the Rangeley Lakes region). Flying squirrels are widespread but seldom seen; look for them in mature mixed woods with snags. Your best odds for gray squirrels are in Portland or Augusta. For red squirrels, drive the roads through the White Mountain National Forest.

4. What is the best time of year to see squirrels in Maine?

Squirrels are active year-round, but fall is prime time. In September and October, gray squirrels are busy gathering acorns and are often seen on the ground. Red squirrels are also active storing cones. Winter is good for spotting dreys (leaf nests) in deciduous trees. Flying squirrels are easiest to detect by listening for their calls on warm nights from late spring through early fall.

5. How can you identify squirrel nests (dreys) in winter?

Once leaves have fallen, look for large, round clumps of leaves high in tree forks. Gray squirrels build messy dreys about a foot wide. Red squirrels make smaller, compact nests in conifers, often using moss and bark. Flying squirrels nest in tree cavities or old woodpecker holes. Scanning treetops on a winter walk is a great way to estimate squirrel populations.

6. Are there any lookalike species to watch for?

The only common lookalike is the Eastern chipmunk, but it is much smaller with distinct stripes. In northern Maine, the American marten could be mistaken for a red squirrel at a glance, but martens are larger with a longer body and no ear tufts. Stick to the eye ring and size to confirm red squirrels. For more on this topic, check our field guide onlookalike rodents.

7. What squirrel-themed gear can show off your sightings?

After a day of spotting, consider wearing your interest. The Wild Wings Wildlife T-Shirt Gray Squirrel has a clean front print that matches the gray squirrel's colors. For a more vintage look, the Squirrel Lover Vintage T-Shirt is a fun option. Browse our full selection at thet-shirt collection.
