Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

This species is found in the northern Columbia basin. They are very local and rare with their numbers seriously declining.

Good habitats in the core areas of use were grass and shrub savanna in the Three-tip Sage and Central Arid steppe zones, plus grassy openings in the lowest edges of the Ponderosa Pine zone. Its favored habitats of grasslands have been largely converted to agriculture, leaving very little space for this species. Undoubtedly this Grouse was much more common in the past than it is now. It is likely that this conversion of their favored habitat has caused some of the disturbing declines that have been noted over the past 40 years.

Additional notes:

This species is threatened in Washington State and a federal species of concern. It occurs year-around in Alaska and the Yukon, and south to Alberta, east to Quebec, South Dakota, Minnesota and Wisconsin. It is also seen in eastern Washington, Idaho, Utah, Wyoming and Colorado.
