Mammals are a class of vertebrate animals (including humans) in which females possess mammary glands, while both males and females possess sweat glands, hair, three middle ear bones used in hearing, and a neocortex region in the brain.

Some of the mammals now common in our area were introduced from elsewhere, such as the black rat, brown rat, Eastern gray squirrel, feral cat, house mouse, Virginia opossum, and wild boar. However, the mammal species listed below are native to the Yuba-Sutter area, having lived here long before the arrival of Europeans.
