Big-eared woodrat

The big-eared woodrat (Neotoma macrotis) is a nocturnal rodent of the woodrat genus Neotoma, in the family Cricetidae. Closely related to, and formerly included in the species Neotoma fuscipes, it is endemic to western North America and occurs west and south of the Salinas Valley from the California Coast Ranges south of Monterey Bay to northern Baja California, as well as in the Sierra Nevada, extending north to the South Fork American River.

The big-eared woodrat is light to dark brown in color, often with a lighter underside. It has characteristically large mobile ears, large eyes, and a long, fur covered tail. It is a primarily arboreal herbivore and functions as an important keystone species in oak and other forest ecosystems.
