Taxonomic Comments
Includes Texas Panhandle population, formerly regarded as distinct species P. comanche. See Carleton (1989), Janecek (1990), and DeWalt et al. (1993) for evidence supporting conspecificity of comanche and truei. Subspecies gratus is now regarded as distinct species (including former truei subspecies gentilis, erasmus, zapotecae, and part of truei).
Conservation Status
Review Date1996-11-08
Change Date1996-11-08
Range Extent Comments
Southwestern and Central Oregon, northern Nevada, northern Utah, western and southern Colorado south to northern Baja California, southeastern Arizona, and southern New Mexico; disjunct population in northern Texas (formerly regarded as separate species, P. COMANCHE) (Carleton 1989; Musser and Carleton, in Wilson and Reeder 1993).
Ecology & Habitat

Habitat

Often among rocks or on rocky slopes (but rocky terrain not required) in a wide variety of habitats including: pinyon- juniper woodlands, chaparral and desert scrub areas, limestone cliffs, redwood forests, riparian woodlands. Nests among rocks; may also nest in trees. Individuals use multiple daytime sites (Hall and Morrison 1997).

Ecology

In California, home range averaged 2.9 ha for 8 males, 0.8 ha for 7 females; the relatively large homes ranges may have reflected the effects of drought and reduced food availability (Hall and Morrison 1997). In New Mexico, median home range size was 0.4-1.6 ha, varying with sex and the method used (Ribble and Stanley 1998).

In northern New Mexico, based on short-term data, mean home range size (minimum convex polygon) was 0.41 ha (trapping data) or 0.93 ha (radiotelemetry) (Ribble et al. 2002).

Reproduction

Breeds primarily in spring and summer, throughout most of year in Arizona and in some areas of California and Nevada (see Kirkland and Layne 1989). Average number of litters per year is 3.4 in central California. In New Mexico and Colorado, gestation lasts 25-27 days (nonlactating) or about 40 days (lactating). Litter size averages about 3-4. Average life span is less than 1 year.
