The gray-crowned rosy finch or gray-crowned rosy-finch is a species of passerine bird in the family Fringillidae native to Alaska, western Canada, and the north-western United States.

Yukon is in the northwestern corner of Canada and is bordered by Alaska, British Columbia and the Northwest Territories. The sparsely populated territory abounds with natural scenery, snowmelt lakes and perennial white-capped mountains, including many of Canada's highest mountains. The territory's climate is Arctic in territory north of Old Crow, subarctic in the region, between Whitehorse and Old Crow, and humid continental climate south of Whitehorse and in areas close to the British Columbia border. Most of the territory is boreal forest with tundra being the main vegetation zone only in the extreme north and at high elevations.
