Horned Lark - Eremophila alpestris
FWP Conservation Tier
Small, ground-dwelling oscine with "horns" - occipital feather tufts - which can be raised or lowered but are usually erect in males. Males slightly larger and darker than females. Basic plumage: nape, back, rump, and dorsal surfaces of the rectrices and remiges are shades of brown streaked with dusky brown to black. Breast and abdomen cinnamon to white. Head strikingly marked with black lores, cheek patches, the occipital feather tufts, and breast patch. Geographic variation is most obvious in body size and coloration, especially of the eyebrow stripe, throat, and ear coverts which vary from white to yellow. The variation in back color is strongly correlated with the color of the local soil. During winter, often occurs in mixed flocks with other species such as longspurs, Snow Buntings, and pipits (Beason 1995).

Open, generally barren country; avoids forests. Prefers bare ground to grasses taller than a few cm (Beason 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 (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.

In winter, mostly seeds. During the breeding season, adults eat mostly seeds but feed insects to their young. Adults take more insects during the spring and fall than at other times, perhaps to compensate for the energetic demands of breeding and molt (Beason 1995).
May nest on marshy soil but generally prefers, throughout its range, bare ground such as plowed or fall-planted fields. Digs a nest cavity or may use a natural depression. Eggs are ovate; ground color varies from dark pearl gray to pale gray, and are spotted. Clutch size varies 2 to 5 eggs (Beason 1995). Nests in Teton County have been found from April 10 to July 19. Nests with eggs as early as May 10 have been found in the Bozeman area.
