Conservation

Conservation DecliningSooty Grouse populations declined by almost 2% per year between 1966 and 2014, resulting in a cumulative loss of 57%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 2 million with 47% living in the U.S., and 53% in Canada. Sooty Grouse is a U.S.-Canada Stewardship species and is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action.Back to top
