USA Ruffed Grouse Range Map
Ruffed grouse range across the northern forests of the United States — the classic 'king of game birds' of northern woods hunting.
What this map shows
The shaded green area is the species' primary contiguous range as mapped by the USGS Gap Analysis Project in 2001. This represents the areas where populations are established, breeding, and ecologically meaningful — not individual sightings or scattered isolated populations.
An unshaded state doesn't mean the species is absent — it only means the species isn't part of the contiguous breeding range at the scale USGS mapped. Small, localized, or recently-reintroduced populations may exist in unshaded areas.
Important: data is from 2001
This is the best publicly-available research-grade range data for the species, but it was compiled from observations collected between roughly 1990 and 2001 and published by USGS in 2011. Many species have expanded significantly since then.
Examples: black bears have recolonized much of the Midwest and South, elk have been reintroduced in Kentucky, Virginia, Wisconsin, and Missouri, gray wolves have expanded substantially in the Northern Rockies and Western Great Lakes, and wild turkeys have pushed into the northern plains. For current distribution, always check your state wildlife agency.
Hunting notes
Strongholds in Minnesota, Wisconsin, Michigan, Pennsylvania, New York, and New England. Hunted with pointing and flushing dogs in young aspen forests and alder thickets. Populations follow a roughly 10-year cycle.
