The gray-tailed vole, Microtus canicaudus, is a common small mammal that inhabits grasslands in the Willamette Valley of western Oregon. Gray-tailed voles are polygamous; females are territorial, males have large home ranges that overlap those of several females, and juvenile emigration is male-biased.
Gray-tailed voles recognize relatives based on familiarity. Under laboratory conditions, familiar gray-tailed voles produced fewer litters than unfamiliar individuals, and pairings of relatives show lower pup survivorship than pairings of unrelated individuals.
