Yellow Rail - Coturnicops noveboracensis
The Yellow Rail is a secretive, often overlooked bird as it prefers to run and hide instead of flying when flushed. The smallest rail in Montana, the Yellow Rail measures 7.25 inches in length, has a wingspan of 11 inches, and weighs up to 55 grams. The sexes are similar in plumage; generally yellow-buff, with a dark brownish-black crown and buffy-brown back streaked with deep brown and black. The feathers of the lower back, scapulars, and tertials have at least 2 distinctive white bars. The chin and upper throat are light- to nearly-white, and the legs are brownish to greenish (Bookhout 1995, Sibley 2000). Though similar in appearance, males are generally larger than females and have an entirely yellow bill during the breeding season, which returns to the olive-green of the female in the fall (Bookhout 1995). The iris appears dark but is yellowish-brown to reddish in the adults (Bookhout 1995). The chicks have a pink bill and are black in color. The bill fades and eventually becomes black in its juvenile stage. The juveniles are of a similar appearance to their parents, but are more speckled overall and the dark patterning on the head is less distinct. The bill is olive-green (Sibley 2000).
The vocalization of the species, by both sexes, is described as a series of clicking noises, usually in a 5-note pattern, "click-click-click-click-click
", each click lasting for 0.1 second and spaced 0.1 to 0.25 second apart (Bookhout 1995). Other calls may include a ten note descending cackle, with three or four notes that sound like distant knocking on a door, soft croaking, or quiet wheezing or clucking notes (Sibley 2000). Although calling usually occurs during the night, with the males sometimes calling incessantly, diurnal activity has also been reported (Bookhout 1995). Young chicks and juveniles give various sounds described as "wees
" and "peeps
" (Savaloja 1981).
For a comprehensive review of the conservation status, habitat use, and ecology of this and other Montana bird species, please see Marks et al. 2016, Birds of Montana.
This species of rail is distinguishable from the Sora by its smaller size, more yellow-buff to buff appearance, the striped yellow and black upper parts with small white crossbars and a short bill. The primaries and secondaries are primarily white, which are apparent when the bird is flushed, and are a distinctive feature of this species (Bookhout 1995). The young are darker and are more obviously specked overall than the juvenile Sora (Sibley 2000).

Yellow Rails probably occur as migrants on their way to and from Canada and wintering areas (California or the Gulf Coast). The earliest observation of the species in the state has been reported for May, with observations also for June, July, and August (Wright 1996, Montana Bird Distribution Committee 2012). Fall migration can occur as early as mid-August and continues to late October (Montana Bird Distribution Committee 2012, Goldade et al. 2002).
Breeding habitat selection is similar to that of other locations, and consists of wet sedge (Carex spp.) meadows and other wetlands containing grasses, rushes (Juncus spp.) and bulrushes (Scirpus spp) (Goldade et al. 2002). Presence of the Yellow Rail is most commonly dictated by water depth, specifically one that fluctuates throughout the breeding season, i.e. wet in the early part of the breeding season and relatively dry (no standing water) by July or September (Goldade et al. 2002).
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: 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.

Reported foods of the Yellow Rail diet include small snails, insects, seeds, grasses, and clover leaves (Terres 1980). Vegetation and invertebrates are the most common foods consumed. Most of the feeding activity takes place during the daytime, when birds have been seen with their heads 1.5 inches under the water while searching for food (Savaloja 1981). In Minnesota rails feed on the snail Succinea retusa (Savaloja 1981). Adults will feed on snails and small invertebrates found in dry grass, as well as seeds, grasses, and clover leaves found in sedge marshes. During rearing, the snails are an important food resource for the young.
Male territories are an average of 7.8 hectares (19 acres), and are established within one week of their arrival (Bookhout and Stenzel 1987). Territories may encompass multiple female activity areas. The activity areas used by females average 1.2 hectares (3 acres) during pre-incubation, decreasing to 0.3 hectare (0.7 acres) during incubation (Bookhout and Stenzel 1987). Adult birds are flightless for several weeks during molting (mid- to late August) (Savaloja 1981).
Limited information on breeding habits of the Yellow Rail is known for Montana. Breeding is suspected in the Westby area and at Medicine Lake National Wildlife Refuge, though no nests or young have been observed (Montana Bird Distribution Committee 2012). Appropriate habitat, sedge marsh or wet meadow, exists at both of these locations.
Although no management activities are in place specifically addressing the Yellow Rail in Montana, water level manipulation for other nesting species occurs at most locations where rails are found. Conscious management of water levels for waterfowl could assist in maintaining or enhancing nesting habitat for the Yellow Rail. Outside of the national wildlife refuges, no activities are known that consider conservation of Yellow Rails. Yellow Rails are a Species of Management Concern in U.S. Fish and Wildlife Service Region 6 (USFWS 1995).
