General Description
The Bobcat is about twice the size of a domestic cat and is the smallest of our native cats. Individuals exhibit considerable variation in color. Base coloration can be light gray, yellowish-brown, buff, brown, or reddish-brown. Under-parts and inside of legs are white with black or dark brown spots. Facial fur is often streaked with black. Dorsal surfaces of the ears are black with a prominent white spot. Short tuft of black hair is present on the ears. This cat has a short tail, black only on the upper portion of the tip. Bobcat fur is short, dense, and soft. Retractile claws. Total length: 28 to 37 inches. Weight: 15 to 35 pounds.
Diagnostic Characteristics
Differs from Canada Lynx: Bobcat paws are much smaller than, and lack large furry pads characteristic of, Canada Lynx. Bobcats also have shorter legs. Canada Lynx has black color all the way around the tail tip. Differs from other cats with short tail.

Migration
Non-migratory. Sometimes extensive movements, e.g. juvenile ranges of 222.1 sq. km (Brainerd 1985).
Habitat
Utilizes wide variety of habitats; known to be an animal of "patchy" country. Prefers rimrock and grassland/shrubland areas. Often found in areas with dense understory vegetation and high prey densities. Natural rocky areas are preferred den sites. May be active during all hours but is primarily nocturnal. Solitary animal that is difficult to observe in the wild. In central MT, selected for cover types (52+% canopy cover) corrected with high prey densities (Knowles 1981). In western MT, den sites within caves, between boulders, in hollow logs, or abandoned mine shafts (Brainerd 1985).
Ecological Systems Associated with this Species
- Details on Creation and Suggested Uses and Limitations
How Associations Were Made
We associated the use and habitat quality (common or occasional) of each of the 82 ecological systems mapped in Montana for
vertebrate animal species that regularly breed, overwinter, or migrate through the state by:
- Using personal observations and reviewing literature that summarize the breeding, overwintering, or migratory habitat requirements of each species (Dobkin 1992, Hart et al. 1998, Hutto and Young 1999, Maxell 2000, Foresman 2012, Adams 2003, and Werner et al. 2004);
- Evaluating structural characteristics and distribution of each ecological system relative to the species' range and habitat requirements;
- Examining the observation records for each species in the state-wide point observation database associated with each ecological system;
- Calculating the percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system to get a measure of "observations versus availability of habitat".
Species that breed in Montana were only evaluated for breeding habitat use, species that only overwinter in Montana were only evaluated for overwintering habitat use, and species that only migrate through Montana were only evaluated for migratory habitat use.
In general, species were listed as associated with an ecological system if structural characteristics of used habitat documented in the literature were present in the ecological system or large numbers of point observations were associated with the ecological system.
However, species were not listed as associated with an ecological system if there was no support in the literature for use of structural characteristics in an ecological system,
even if point observations were associated with that system.
Common versus occasional association with an ecological system was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species as represented in scientific literature.
The percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system was also used to guide assignment of common versus occasional association.
If you have any questions or comments on species associations with ecological systems, please contact the Montana Natural Heritage Program's Senior Zoologist.
Suggested Uses and Limitations
Species associations with ecological systems should be used to generate potential lists of species that may occupy broader landscapes for the purposes of landscape-level planning.
These potential lists of species should not be used in place of documented occurrences of species (this information can be requested at:
mtnhp.org/requests) or systematic surveys for species and evaluations of habitat at a local site level by trained biologists.
Users of this information should be aware that the land cover data used to generate species associations is based on imagery from the late 1990s and early 2000s and was only intended to be used at broader landscape scales.
Land cover mapping accuracy is particularly problematic when the systems occur as small patches or where the land cover types have been altered over the past decade.
Thus, particular caution should be used when using the associations in assessments of smaller areas (e.g., evaluations of public land survey sections).
Finally, although a species may be associated with a particular ecological system within its known geographic range, portions of that ecological system may occur outside of the species' known geographic range.

Food Habits
Snowshoe Hares and jack rabbits are the most common prey. Also feeds heavily on medium-sized rodents. Will eat carrion.
Ecology
In western MT, annual average home ranges (AD): females=58.6 sq km, males=79.0 sq km. North-central MT, adult male=83.3 sq km. Reproducing females exhibit reduced movements. Density estimated 1 adult/49.8 sq km in central MT (Knowles 1981 and Brainerd 1985).
Reproductive Characteristics
Usually mates during spring. Litter size averages from two to four. Gestation 50 to 60 days. Young born May through June. Litter size 1 to 6, rarely over 4, averages 2.69 young/litter. Yearling pregnancy rate 39.4%, adult pregnancy rate 89.6%. No significant differences detected between litter sizes or ovulation rates in eastern or western Montana (Brainerd 1985).
