There is little information on population trends of Spruce Grouse, but habitat loss is a threat to the species, and appears to have caused a dramatic reduction or elimination of populations in some areas. Partners in Flight estimates a global breeding population of 11 million with 19% living in the U.S., and 81% in Canada. The species rates an 8 out of 20 on the Continental Concern Score. Spruce Grouse is a U.S.-Canada Stewardship species and is not on the 2014 State of the Birds Watch List. These birds have historically inhabited forests showing a fire-related patchwork of various stages of regeneration; timber harvesting can produce similar patterns, but only if clear-cut areas are small and if sufficient quantities of optimal habitat are preserved. Spruce Grouse is listed as "endangered" or "threatened" in some states at the edge of its range. Back to top
