Pikas Live High

Pikas live at extremely high elevations, collecting leaves and grasses each summer. They lay the vegetation outside to dry and then make separate hay piles to sustain themselves through winter. Unfortunately, pikas are being driven to higher elevations because of global warming. At these levels, there is less vegetation, which means less food for these feisty little mammals.
