Collie’s squirrel or Pacific gray squirrel
The western gray squirrel (Sciurus griseus) is an arboreal rodent found along the west coast of the United States and Mexico. It's a tree squirrel. In some places, this species is also known as silver gray squirrel, California gray squirrel, Oregon gray squirrel, Columbian gray squirrel, and banner tail. There are three geographic regions: Sciurus griseus griseus (from central Washington west to the Sierra Nevada and central California); s.g. nigripes (from southern San Francisco Bay to San Luis Obispo County, California); and S.g. anthonyi (from San Luis Obispo to northern Baja California).
The western gray squirrel has a long bushy, white tail, which helps the animal balance itself as it jumps from tree to tree. His feet are too big. During the winter months, the famous ears are red-brown and back. This mouse is actually the largest tree squirrel in Washington. The animal has a white underparts and a salt-and-pepper to gray back.

This range extends across the Pacific region of the western United States and northern Mexico, from northern Washington State to the northern tip of Baja, California. The western gray squirrel lives mostly in forests and coniferous forests. Attitudes and ways of life
The western gray squirrel is an active diurnal animal. The mouse spends most of its time outside the nest, feeding, exploring the environment, feeding and resting. They often combine research with food, while dressing takes 3-15 minutes, which is spent a lot of time in the head. Food is carried into the nest and buried in each individual's area. If necessary, they can find stored food because of their good sense of smell. Each person has his territory of 0.5 to 7 hectares on average. The territory of women is smaller than that of men. These rats do not sleep. However, during the winter, they prefer to stay in their nests. Western gray squirrels are usually solitary and non-territorial except for females in estrus. If a squirrel is threatened, it will make a clicking sound, accompanied by tail beating and stomping. Food and food
The western squirrel's diet is its habitat. People who live in coniferous forests mainly eat pinecones, while people in forests eat grass and acorns. In general, these mice prefer tomatoes, mushrooms, bark, sap and various insects. Population
The threat of crowding
Since the early 1900s when eastern squirrels were introduced to the Los Angeles, Southern California area, the western squirrel population has suffered greatly from this kind of violence. Many of the residents have died due to various diseases, road accidents and damage to their homes. Other populations have migrated to the mountains and hills due to urbanization, deforestation, consumption, and the destruction of their habitats. Number of inhabitants
According to the IUCN, the western squirrel is rare but widely distributed and no population estimates are available. Currently, this species is classified as Least Concern (LC) on the IUCN Red List.
