Yellow-breasted Chat - Icteria virens
The largest wood warbler: robust build, large bill with strongly curved culmen, long tail, and distinctive plumage distinguish this species from all other wood-warblers and similarly colored songbirds. Upper parts olive-green to grayish-olive; chin, throat, and breast lemon-yellow (sometimes tinged with orange), contrasting with mainly white belly and under tail-coverts. Face grayish with black lores, white supercillium, and white eye-crescent on lower eye-lid. Sexes very similar, but during breeding season, female has grayish lores, gray lower mandible, and pink mouth-lining, in contrast to male's black. Little seasonal change although upperparts more brownish, yellow underparts more olive, and flanks more buffy or brownish, and bill more brownish in winter (Eckerle and Thompson 2001).

Found in low, dense vegetation without a closed tree canopy, including shrubby habitat along stream, swamp, and pond margins; forest edges, regenerating burned-over forest, and logged areas; and fencerows and upland thickets of recently abandoned farmland (Eckerle and Thompson 2001).
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.

Adults feed on small invertebrates (mainly insects and spiders), fruit and berries when available (Eckerle and Thompson 2001).
Nests usually placed near ground in dense thickets and shrubs that provide concealment. Eggs are ovate to subelliptical in shape; color white or creamy-white with reddish brown, chestnut red, brown, and paler gray or purple speckles. Clutch size varies form 3 to 5 eggs (Eckerle and Thompson 2001). Eggs have been observed June 11 and 19.
