Brush rabbit

Description

The brush rabbit (Sylvilagus bachmani), or western brush rabbit, or Californian brush rabbit, is a species of cottontail rabbit found in western coastal regions of North America, from the Columbia River in Oregon to the southern tip of the Baja California Peninsula. Its range extends as far east as the eastern sides of the Sierra Nevada and Cascade mountain ranges. The brush rabbit is a small rabbit with short legs and a short tail. It is dark gray on the sides and back, and pale gray on the belly and the underside of the tail. The whiskers are mostly black, although some have white tips. Adult rabbits measure anywhere from 303 to 369 mm (11.9 to 14.5 inches) in length, and range in weight from 511 to 917 grams (18 to 32 ounces). Large numbers of geographically defined subspecies have been proposed, including in Oregon, ubericolor; in California, cinerascens, mariposae, riparius, tehamae and trowbridgii; and in Baja California, cerrosensis, exiguus, howelli, peninsularis and rosaphagus. Subspecies bachmani, macrorhinus and virgulti are less geographically restricted. Of the various proposed subspecies, only the following are currently recognized; the others are synonyms: S. b. ubericolor, S. b. cinerascens, S. b. bachmani, S. b. exiguus, S. b. howelli, S. b. cerrosensis. It has been noted that numbers of the eastern cottontail were brought west to reproduce and provide a food source for the settlers. The interbreeding of the two species has occurred where the brush rabbit has in parts of Oregon developed the white cottontail although retaining its smaller size. Brush rabbits require dense bramble clumps or other thick brushy habitat. These bramble clumps often have extensive networks of trails and runways. The species will occasionally use burrows made by other species, but does not dig its own. The home range is very small, less than 2000 square meters.
