Western Wood-Pewee - Contopus sordidulus
FWP Conservation Tier
Total length is 14 to 16 cm. Female is slightly smaller than the male. Upperparts are uniformly dark grayish brown, wings have indistinct pale wing-bars and tertial edges; underparts are dull whitish becoming dusky on breast and flanks; upper mandible dark, lower mandible paler with dark tip or all dark (Bemis and Rising 1999).

In the Bozeman area, normal migration periods are May 30 to June 10 and August 25 to September 5 (Skaar 1969).
Western Wood-pewee are seen wherever there are clearings or groves of deciduous trees along the river valleys (Davis 1961).
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 (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.

This species is primarily a sit-and-wait predator, sallying from open perches and usually returning to the same or nearby perch in pursuit of flying insects, especially flies, ants, bees, wasps, and beetles, moths and bugs (Bemis and Rising 1999).
Probably seasonally monogamous. Nest site may be selected by male and female together. Clutch size is 2 to 4 eggs, usually 3 (Bemis and Rising 1999). Nests with young are seen to mid-August. Nests with eggs have been seen as early as July 8 (Davis 1961). Young have been seen in the nest in mid-June on Flathead Lake.
