Conservation

Conservation Low ConcernWhite-tailed Ptarmigan is not on the 2014 State of the Birds Watch List. Partners in Flight estimates a global breeding population of 2 million birds, with 28% living in the U.S., and 73% in Canada. The species rates an 11 out of 20 on the Continental Concern Score. Ptarmigans have experienced some disturbances, including overgrazing by livestock and development of ski areas, that may affect distribution locally. Management of hunting bag limits, seasonal closure and rerouting of roads, and limitations on livestock grazing help to stabilize White-tailed Ptarmigan populations.Back to top
