Lesser Yellowlegs - Tringa flavipes
A medium-sized (length tip of bill to tip of tail: 230 to 250 mm, body mass: 67 to 94g) shorebird, usually recognized by its long, bright-yellow legs, long neck, graceful stride, and distinctive "tu tu
" call. Sexes are similar in plumage and overall size, females have slightly longer wings on average. Breeding plumage: upperparts mottled gray-brown, white, and black. Underparts white with brown streaking on neck and breast and irregular, blackish barring on anterior flanks. Basic plumage: upperparts uniform gray to gray-brown with pale spots. Underparts white with fine gray streaking on neck and breast (Tibbitts and Moskoff 1999).

In the Bozeman area, migration periods are from April 28 to May 12 and July 27 to October 10, with peaks around May 4 and September 10 (Skaar 1969).
In summer, breeders are conspicuous residents of open woodlands, meadows, and muskegs in the boreal zone from northwestern Alaska to central Quebec. In winter, they frequent a wide variety of wetland types throughout Central and South America (Tibbitts and Moskoff 1999). A migrant. It occurs in high numbers in interior North America. Primary routes are mid-continent, mostly west of Mississippi River in spring and both along Atlantic coast and mid-continent in fall (Tibbitts and Moskoff 1999). During migration, it occurs along mudflats and shallow ponds, often with vegetated shorelines. Sometimes they occur in flooded fields (Johnsgard 1986).
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.

Aquatic and terrestrial invertebrates, particularly flies and beetles. Occasionally, small fish and seeds (Tibbitts and Moskoff 1999).
Typically nests on dry, mossy ridges or hummocks, next to fallen branches and logs, and underneath low shrubs or small trees. Eggs are ovate pyriform in shape and smoke gray with markings in color. Clutch size usually 4. Montana not included in breeding range (Tibbits and Moskoff 1999).
