| Douglas's Squirrels are small, energetic, and very active during the day all year long. They spend many hours collecting and storing green pine cones to eat during the harsh winters. Each squirrel builds several nests, including an underground nest for winter use. They usually breed from March to June, and sometimes again in late summer or early fall, and other than that, are solitary. Females have eight teats, and litters of eight have been recorded, but litters of 4-6 are more usual.
