Forests from sea level to alpine (Armstrong 2008). In Alaska, occurs in wet coastal forests of southeast and taiga forests of north central and eastern Alaska. Found in spruce forests, deciduous (balsam poplar and dense alder stands), and mixed forests (Kessel 1989, Kessel 1998, George 2000). Thick, wet (although occurs in some drier areas of the taiga), shady, mossy forests and deciduous shrub and thickets. Also found beyond the forest taiga, in dense alder thickets, and isolated cottonwood patches (Kessel 1998). May forage in open tundra (Kaufman 1996, Armstrong 1995).
