Virginia Rail - Rallus limicola
Small (22 to 27 cm) dorsally compressed, reddish bird with gray cheeks and a long, slightly decurved bill. Wings chestnut-colored with a 1-mm claw on outer digit and reduced 11th primary. Legs and bill reddish, flanks banded black and white. Females smaller than males. Clapper and King Rails are much larger with less red on bill and less gray on cheeks. A secretive freshwater marsh bird that is more often heard than seen. Duetting "grunt" vocalizations signal the start of the nesting season each spring (Conway 1995).

Breeds predominantly in freshwater wetlands, but nests have been reported in salt marshes. Shallow water, emergent cover, and substrate with high invertebrate abundance are thought to be the most important features. Needs standing water, moist-soil, or mudflats for foraging. Winter range includes both freshwater and salt marshes, generally similar to breeding habitat (Conway 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.

Breeding season: small aquatic invertebrates, mainly beetles, snails, spiders, true bugs, and diptera larvae. Winter: invertebrates, a variety of aquatic plants, and seeds of emergent plants (Conway 1995).
Adults build numerous "dummy" nests within their territories in addition to their primary nest. Nests in robust emergent vegetation (e.g., cattails, bulrush). Nests are well concealed; built touching, slightly submerged below, or a short distance (less than 15 cm) above water surface. Eggs are oval, variable in color (creamy white to buff, sparingly and irregularly spotted). Mean clutch size = 8.5 eggs (Conway 1995). There are several nest records for Wyoming in mid-May. Nesting phenology here is probably similar.
