Study: In California desert NPs, burrowing animals more able to deal with climate change than birds

Though birds presumably could fly to cooler temperatures as the climate heats up, studies show that burrowing animals in places such as Death Valley National Park and Mojave National Preserve in California are better able to endure higher temperatures than their feathered counterparts.

The bottom line, researchers say, is that species such as kangeroo rats, the white-tailed antelope squirrel, and the cactus mouse can rather easily cool off by heading down into their burrows, while birds don't have such naturally cooled environments to retreat to.
