White-footed Mouse - Peromyscus leucopus
Adults are reddish brown (juveniles gray), with a white belly, white feet, membranous ears, and bicolored tail (usually not sharply bicolored); adult total length 145 to 205 mm, tail 62 to 97 mm (usually shorter than head and body), hind foot 18 to 24 mm, ear 13 to 19 mm; 16 to 29 g in the northeastern U.S.; 3 pairs of mammae (Paradiso 1960, Godin 1977, Hall 1981).
Often difficult to distinguish from P. maniculatus. In New England, differs from P. maniculatus by having coarser and redder pelage, a more well-defined mid-dorsal stripe, a tail that is less distinctly white on the ventral surface and that seldom is as long as the head and body, and a broader rostrum (Godin 1977). See Hoffmeister (1986) for differences from Peromyscus species in the southwestern U.S.

How Associations Were Made
We associated the use and habitat quality (high, medium, or low) 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 2001, 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 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 associated as using 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 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.
High, medium, and low habitat quality was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species in the 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 assignments of habitat quality.

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: http://mtnhp.org/requests/default.asp
) 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.

Somewhat omnivorous. Seeds, fruits and insects are dominant items, with order of importance varying between season and ranges.
Probably restricted to warmer months with peaks in March to April and September to October, in midsummer heat reporduction may slow down.
