"Douglas Squirrel," Wikipedia, the free encyclopedia. The Douglas squirrel is a pine squirrel found in the Pacific coastal states and provinces of North America. It is sometimes known as the chickaree or pine squirrel, although these names are also used for the American red squirrel. John Muir described the Douglas squirrel, Tamiasciurus douglasii, as "by far the most interesting and influential of the California sciuridę". Adults are about 33 cm in length (including its tail, which is about 13 cm long), and weigh between 150 and 300 grams. Their appearance varies according to the season. In the summer, they are a grayish or almost greenish brown on their backs, and pale orange on the chest and belly, while legs and feet appear brown. In the winter, the coat is browner and the underside is grayer; also, the ears appear even tuftier than they do in summer. Like many squirrels, Douglas squirrels have a white eye ring.
