About the Brush Mouse

The brush mouse (Peromyscus boylii) is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice". It is found in mountainous areas of Mexico and the western United States at altitudes over 2,000 m (6,600 ft).

The brush mouse is medium-sized, with small ears and a long tail. It has yellowish-brown fur on the body, with slate grey under parts. The tail has only sparse hair for most of its length, but with a distinct brush-like tuft of hair at the tip (although the common name is, perhaps, more likely to come from brushy environment in which it lives). It has a head-body length of 86 to 105 mm (3.4 to 4.1 in) with a tail 88 to 115 mm (3.5 to 4.5 in) long. It is very similar in appearance to a number of closely related species of mouse living in the same area, although it can be distinguished from them by such features as the length of its tail, the size of its ears, and the presence of the tuft on the end of the tail.

The brush mouse can be found from northern California to eastern Colorado and western Texas, and south to Baja California and southern... Wikipedia →
