The Ptarmigan: a ‘canary’ for climate change?
The Ptarmigan, a mountain bird known in Colorado for its camouflaged exterior, may be at risk due to climate change. Because the birds are limited to alpine habitats, scientists worry for their survival as temperatures rise and snow and ice melt. Last week, environmentalists began a campaign to designate the bird as a threatened species. If the designation is accepted and approved by the U.S. Fish and Wildlife Service, it would require action to combat the threat of climate change, which could lead to legislation to reduce carbon emissions.
