According to Science News, coping with heat waves can demand so much water evaporation to prevent heat stroke — from panting, for instance — that birds can die from dehydration. Small species like the lesser goldfinch dehydrate at a proportionately higher rate than larger birds such as towhees. With a temperature rise of just a few degrees, a lesser goldfinch could face a risk of death within five hours on as many as 120 days a year in the worst hot spots.
