White-crowned Sparrow - Zonotrichia leucophrys
A small oscine, sexually monomorphic in plumage but geographically variable. Definitive Basic and Alternate plumages essentially the same. Top of head with 2 broad black stripes, separated by a broad median white stripe. Eyebrow-stripe white, cut off at lore by black crown-stripe in some subspecies. Narrow black line extends from eye to back of nape. Remainder of face, sides of neck, and breast gray, fading to white on throat and abdomen. Back and scapulars light gray streaked with brown. Rump and uppertail-coverts pale brownish. Wings with 2 white wing-bars. Tail dark brown. Legs grown to flesh-pink. Iris brown. Bill color varies with subspecies, pinkish brown to yellowish (Chilton et al. 1995). See Dunn et al. (1995) for detailed information on identification of subspecies.
For a comprehensive review of the conservation status, habitat use, and ecology of this and other Montana bird species, please see Marks et al. 2016, Birds of Montana.

In the Bozeman area, normal migration periods are May 5 to 30 and August 20 to October 15, with a peak on September 25.
Necessary habitat features of breeding territories include grass, either pure or mixed with other plants; bare ground for foraging; dense shrubs or small conifers thick enough to provide a roost and conceal a nest; standing or running water on or near territory; and tall coniferous trees, generally on periphery of territory. The first 3 features seem characteristic of nesting habitat of all populations (Chilton et al. 1995).
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: 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.

Main foods taken in winter include seeds, buds, grass, fruits, and arthropods, when available. During breeding season arthropods (principally insects) and seeds are taken (Chilton et al. 1995).
Usually place nest in shrub vegetation above ground. At higher latitude or altitude, nests more likely to be located on the ground. Eggs are ovate, greenish to greenish-blue or bluish in color and marked with reddish brown spots or blotches. Clutch size ranges 3 to 7 eggs (Chilton, et al., 1995). The species nests during June, July and early August.
