The Douglas Squirrel (Tamiasciurus douglasii) is a pine squirrel occurring in a belt along the Pacific coast from California to southern Alaska. The small mammals live in coniferous forests where they inhabit territories of around 10 000 square metres. They are active during the day foraging for seeds of conifers which constitute most of their diet. In addition, the squirrels feed on acorns, berries, mushrooms, fruits, and occasionally eggs of birds or invertebrates. During the summer, they build nests in trees for the night. During the colder months, the squirrels take shelter in tree holes or burrows in the ground. I have photographed these pretty little squirrels during a visit to the Sequoia National Park in California in October 2009.
