General Description
The Greater Sage-Grouse is North America's largest grouse.

Diagnostic Characteristics
Both sexes have relatively long, pointed tails, feathered legs, and mottled gray-brown, buff, and black plumage. Males have a blackish-brown throat patch and an inconspicuous yellow eye comb. Both sexes have blackish bellies which contrast sharply with white under-wing coverts when the birds are in flight. Females appear to dip from side to side while flying. Adult males range from 26 to 30 inches in length and average 4 to 7 pounds in weight; adult females range from 19 to 23 inches in length and 2.5 to 3.5 pounds in weight. A female Ring-necked Pheasant (Phasianus colchicus) can possibly be confused with a female or young Greater Sage-Grouse. Female Ring-necked Pheasants, however, have a brown belly and bare legs, while female Greater Sage-Grouse have a black belly patch and feathered legs. They differ from Sharp-tailed Grouse (Tympanuchus phasianellus) in having a black belly and in lacking white outer tail feathers.

Migration
The Greater Sage-Grouse makes seasonal movements that can vary greatly depending upon a number of factors including gender, behavior, seasonal habitat quality, and weather (Connelly et al. 1988).

Habitat
Sagebrush is the preferred habitat. They use 6 to 18 inch high sagebrush covered benches in June to July (average 213 acres); move to alfalfa fields (144 acres) or greasewood bottoms (91 acres) when forbs on the benches dry out; and move back to sagebrush (average 128 acres) in late August to early September (Peterson 1969).


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
Adults eat mainly sagebrush during late autumn, winter, and early spring. Sagebrush and forbs dominate diet in summer, although some insects are also eaten. Typically forages on the ground. Juveniles eat insects such as grasshoppers and ants during the first three weeks of life, but forbs increase with importance with age (Schroeder et al. 1999).

Ecology
Lek activity extends from March to May. Mating sites move from year to year; nests are located 0.2 to 6.5 miles from the lek (Harrison 1972).

Reproductive Characteristics
In southwest Montana 34% of hens observed had broods, with the average size being 4.3 (Martin 1965). Courtship starts in early March and persists to nesting in May (Davis 1961). Egg records are probably similar to Wyoming: April 18 to July 27 (Johnsgard 1986).

Management
On March 5, 2010, the U.S. Fish and Wildlife Service determined that the Greater Sage-Grouse warrants protection under the Endangered Species Act, but that listing the species under the Act is precluded by the need to address other listing actions of a higher priority. Additional information on the species' management can be found on the U.S. Fish and Wildlife Service's Species Account
