General Description
Small, 15 to 17 cm, slender. Males slightly larger and heavier than females. Not seperated by plumage. Bill short, slender, straight. Bobbing tail with white edge to outer tail feathers. Compare with Sprague's Pipit (the sides of the head and indistinct buffy eye-rings are pale. The lores contrast with dark brown eyes and the ear coverts are plain brownish-buff, usually with a slight reddish tinge. The crown, sides and rear of neck are buffy with sharply defined black streaks. The back is light sandy-brown with broad black streaks, with a paler more prominent buffy stripe down each side. The wings, 7.7 to 8.5 cm long, have blackish-brown feathers with whitish to buffy-brown edging, and two whitish wing bars. The rump and upper tail coverts, paler than the back, are sandy-brown with narrow black streaks (Robbins and Dale 1999). However, Sprague's Pipit has a shorter tail with more white in outer rectrices, more strongly marked upperparts, and paler face without the dark auricular patch of the American Pipit (Verbeek and Hendricks 1994).

Migration
In the Bozeman area, normal migration periods are April 20 to May 20 and September 5 to October 22, with a peak around October 1 (Skaar 1969).

Habitat
In the Beartooth Mountains, nest sites required snow-free areas, tussocks, tilted rocks and eroded areas nearby (Verbeek 1965). Ground inhabiting songbird of generally sparsely vegetated, open habitat (Verbeek and Hendricks 1994).

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:
    1. 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);
    2. Evaluating structural characteristics and distribution of each ecological system relative to the species’ range and habitat requirements;
    3. Examining the observation records for each species in the state-wide point database associated with each ecological system;
    4. 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.  If you have any questions or comments on species associations with ecological systems, please contact Bryce Maxell at bmaxell@mt.gov or (406) 444-3655.

    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.

Food Habits
American Pipits eat almost entirely arthropods. On the Beartooth Plateau the major groups found in nestling diets, in order of abundance, were Diptera, Hemiptera, Lepidoptera, Homoptera, Hymenoptera, Coleoptera, and Diplopoda (Hendricks 1987).

Ecology
Mean territory was measured at 1810 square meters. Deer mouse and Long-tailed Weasel were the main predators in the Beartooth Mountains (Verbeek 1970).

Reproductive Characteristics
Statewide, nesting is from early June to mid-August (Davis 1961, Verbeek 1970, Hendricks 1993). In the Beartooth Mountains eggs were laid mid-June to mid-July, the average clutch was 4.6, survival to fledging was 2 per nest, the incubation period was 14 days, the nestling period was 14 days and independence was at 28 days (Verbeek 1965).
