Spruce Grouse - Falcipennis canadensis
FWP Conservation Tier
Both sexes have tail feathers that are unbarred and narrowly tipped with white, and feathered legs. Males are gray and black above, with a black throat and a well-defined black breast patch bordered with white-tipped feathers; they have scarlet eye combs. Females are mostly white beneath but barred with black, gray, and buff. Females are also extensively barred on the head. Adult males and females range from 15 to 17 inches in length and average about 17.5 ounces in weight.
Although they are considerably smaller, Spruce Grouse are most likely to be confused with Blue Grouse. Male Spruce Grouse, however, have a black breast patch, while Blue Grouse do not. Female Spruce Grouse have white under parts with black barring, while female Blue Grouse have bluish-gray under parts. Ruffed Grouse have distinctly banded tails. White-tailed Ptarmigan are smaller thn Spruce Grouse, and are found only in alpine and sub-alpine habitats. In the fall, White-tailed Ptarmigan are reddish-brown above, with belly, tail, and wings of white.

Spruce Grouse in Montana inhabit dense forest types such as alpine fir, Engelmann spruce, or lodgepole pine. Winter home ranges northeast of Missoula are covered by Douglas-fir, ponderosa pine, lodgepole pine and larch. Douglas-fir provided the most important cover; the average size being 24.1 hectars (Paterni 1976). North of Columbia Falls, hens with chicks occupied more open areas in winter (Stoneberg 1967).
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.

Conifer needles (larch, ponderosa pine, lodgepole pine) were the main food in late fall through early spring (Paterni 1976, Stoneberg 1967). In summer, herbaceous vegetation and insects were utilized.
North of Columbia Falls, the density of territorial males was 5 per square mile with home territories of 10 to 15 acres (Stoneberg 1967). 80% of winter observations are of solitary birds; males were always alone, females may be with other females and/or immatures (Paterni 1976).
Predation by Northern Goshawks, Coyotes and Great Horned Owls were the major cause of nest failure. Chicks were reported by mid-July (Davis 1961). Near Fortine, broods of 4 to 6 hatched from June 20 to July 20.
