Heat Waves Could Silence the Southwest’s Songbirds.

Based on climate projections for the Southwest, small birds such as the lesser goldfinch may face lethal dehydration on average 25 days per year by the end of the century. Larger songbirds, such as curve-billed thrashers and Abert’s towhees, lose water at a lower rate, so they won’t be as vulnerable to dehydration until temperatures get much higher. But even bigger birds face risks: For some, small ranges restrict them to hot deserts and unpredictable water sources.
