Alaska deer mouse records are thin next to the western Lower 48: just 46, all from GBIF, and 38 of them come from the Valdez-Cordova area of Southcentral Alaska, with a single record from Juneau in the Southeast, near the northern edge of the species’ range.
Wherever it turns up, a deer mouse wants the same basics: a hidden nest in a hollow log, rock crevice, or old burrow within a short dash of food. In Alaska that might mean a gap under beetle-killed spruce or a mossy nook in coastal old growth. It forages mostly after dark on seeds, insects, and berries, and caches food to get through lean stretches.
Reports cluster from May through July and stay sparse the rest of the year, which reflects how few people are out looking for a small nocturnal mouse across such a big, remote state, not true absence.
