Range
The Coast Range, Willamette Valley, Klamath Mountains, West Cascades, East Cascades, Basin and Range, and Blue Mountains.
Description
Adults are about 14 inches in length including the tail, and weigh between 150 and 300 grams. Their appearance varies according to the season. In the summer, they are grayish with pale orange on the chest and belly. In the winter, the coat is browner and the underside is grayer.
Diet and habitat
They mostly eat seeds of conifer trees, but also consume nuts, fruit, sap, bird eggs, insects and fungi. Unlike many other types of tree squirrels, they lack cheek pouches in which to hold food. Widespread in western Oregon, they inhabit mixed conifer, lodgepole pine, ponderosa pine, white oak and mixed conifer-hardwood forest types.
Predators and threats
Douglas squirrels are preyed upon by hawks, owls, the American marten, bobcats and house cats.
Reproduction
They produce one to eight young per year.
