Grouse are a type of gamebird found in many parts of North America, including Washington state. There are several species of grouse that inhabit different regions of Washington. The main grouse species found in Washington include ruffed grouse, dusky grouse, sharp-tailed grouse, sooty grouse, and sage grouse. Grouse prefer habitats such as forests, meadows, sagebrush flats, mountain slopes, and meadow openings. Understanding the preferred habitat and range of each grouse species can help hunters find the best areas to search for these gamebirds.
Ruffed Grouse
The ruffed grouse is the most common and widely distributed grouse species in Washington. They are found throughout much of the state but are most abundant in the coniferous forests on both sides of the Cascade Mountains. Ruffed grouse populations are found in good numbers in national forests like the Okanogan-Wenatchee, Mount Baker-Snoqualmie, Gifford Pinchot, and Umatilla. Here are some key facts about the habitat range of ruffed grouse in Washington:
- Prefer areas with dense stands of conifers mixed with aspen and birch thickets
- Found at elevations between sea level and 5,000 feet
- Most abundant in riparian areas along streams and wetlands
- Nest and take shelter in brush piles and downed logs
- Forage for buds, seeds, berries and insects on the forest floor
Some prime areas to find ruffed grouse include Mt. Baker, portions of the Cascades near Stevens Pass, coastal forests near Forks, conifer forests around Spokane and forested regions of the Blue Mountains. Overall their widespread range makes ruffed grouse the most common grouse encounter for hunters across Washington.
Dusky Grouse
The dusky grouse, also called the blue grouse, is found throughout mountain forests in Washington. They occur on both sides of the Cascades and throughout mountain ranges in central and eastern Washington. Here are some key facts on dusky grouse habitat:
- Most abundant in higher elevations from 3,500 – 7,000 feet
- Prefer fir forests with dense canopy cover
- Depend on huckleberry bushes in forest openings
- Nest in treetops, typically conifers like Douglas fir
- Forage for leaves, flowers, insects and berries in summer
Prime dusky grouse habitat includes subalpine fir forests in the Cascades, Okanogan Highlands, Blue Mountains and foothills of northeastern Washington. Good populations occur near Mt. Adams, Mt. Rainier, Mt. St. Helens and throughout Okanogan National Forest. They are less common at lower elevations on the eastern and western slopes of the Cascades.
Sharp-tailed Grouse
Sharp-tailed grouse inhabit more open grasslands and meadows in scattered parts of Washington. They are most common east of the Cascades but also occur in limited numbers west of the Cascades. Here is some key information on their habitat range:
- Prefer areas with grasslands, meadows, and openings in shrub-steppe
- Depend on medium to tall grasses and abundant forbs
- Found at elevations below 4,000 feet
- Nest and forage in grassy openings in shrub-steppe habitat
- Eat leaves, buds, seeds, flowering parts of plants and insects
The largest populations of sharp-tailed grouse are found in grassland and steppe regions of eastern Washington. This includes Douglas, Grant, Lincoln and Yakima counties. Smaller numbers occur in areas west of the Cascades in meadows and natural prairie openings.
Sooty Grouse
The sooty grouse is found across mountain forests in the western half of Washington. Its range extends along the Cascades and in forested mountains closer to the Pacific Coast. Key details on sooty grouse habitat include:
- Most common from sea level to 5,000 feet elevation
- Mainly a low to mid-elevation species
- Prefer coniferous forests with dense canopy
- Depend on huckleberries and conifer needles
- Nest on ground near logs, tree trunks
Sooty grouse populations are concentrated in the Olympic Mountains, southern Cascades near Mt. Rainier, Willapa Hills and scattered coastal mountain ranges. The dense conifer forests of the Olympic Peninsula have especially high densities of sooty grouse. They also occur in smaller numbers across forested mountains on the western slopes of the Cascades.
Sage Grouse
Sage grouse inhabit sagebrush steppe habitats primarily in central and eastern Washington. They are found in areas with extensive sagebrush that support their dietary and nesting requirements. Here are key details on their range:
- Occur in sagebrush flats and plains below 5,000 feet
- Depend on sagebrush for food and shelter
- Associated with big sagebrush but also use other Artemisia species
- Nest and brood in sagebrush cover
- Found in shrub-steppe habitats with native grasses
The largest populations of sage grouse occur in Grant, Douglas and Yakima counties where there are expansive sagebrush-steppe habitats. Scattered populations also occur in areas of Adams, Lincoln, Franklin and Okanogan counties as well. Overall, sage grouse distribution is strongly tied to intact sagebrush communities in central and eastern Washington.
Factors Influencing Grouse Distribution
Several ecological factors account for the distribution patterns of grouse in Washington. These include:
- Vegetation composition – Grouse are closely associated with certain plant communities that meet their habitat needs
- Topography – Elevation, landforms, slope, etc. influence what vegetation types occur
- Climate – Temperature, precipitation and moisture patterns help determine vegetation
- Disturbance – Fire, grazing, logging and other disturbances shape grouse habitats
- Fragmentation – Grouse need intact habitats and are affected by habitat loss
Understanding these landscape factors helps explain why each grouse species is found in certain parts of Washington. Ruffed grouse occupy conifer forests along the wetter western region while sage grouse inhabit drier sagebrush steppe in central and eastern parts. The other species fill niches in mountain forests or open meadows. Maintaining large intact areas of suitable vegetation is key to sustaining grouse populations into the future.
Grouse Population Trends
Grouse numbers naturally fluctuate year to year but some species have experienced population declines due to habitat loss. Here are overall population trends:
- Ruffed grouse – Still widespread but declining in some areas
- Dusky grouse – Relatively stable though depend on old conifer forests
- Sharp-tailed grouse – Declines east of Cascades due to habitat loss
- Sooty grouse – Populations generally stable across its forested range
- Sage grouse – Severe historical declines, state and federal protections in place
Ruffed, dusky and sooty grouse populations remain productive enough to allow hunting seasons in most years. However, loss of steppe habitats has caused sharp-tailed grouse and sage grouse to decline substantially from their historical abundance. Ongoing conservation efforts aim to restore enough habitat to sustain grouse numbers into the future.

Hunting Outlook for Grouse
The hunting outlook for grouse varies by species and location. Here is a quick overview:
- Ruffed Grouse – Season runs September to January. Bag limit 3 per day. Outlook is fair to good in many national forests.
- Dusky Grouse – Season September to January. Bag limit 3 per day. Hunting is focused in mountain forests.
- Sharp-tailed Grouse – Season September to November. Bag limit 2 per day. Populations are lower than historically.
- Sooty Grouse – Season September to January. Bag limit 3 per day. Fair opportunities on the Olympic Peninsula.
- Sage Grouse – Very limited general season in select areas. Strict limits and protections.
Hunters should consult regulations for season dates and bag limits in their hunt area. Areas with good habitat typically have the best hunting. Scouting to locate signs like tracks, droppings and feeding areas can improve success. Being properly prepared for variable fall weather in the mountains is also advised. Overall, Washington provides varied opportunities to hunt forest grouse and more limited chances at sharp-tailed and sage grouse.
