- Avian thermoregulation in the heat: resting metabolism, evaporative cooling and heat tolerance in Sonoran Desert songbirds
Summary: Thermoregulatory performance measurements in seven Sonoran Desert passerine bird species show that heat tolerance limits did not scale with body mass among species, but were ∼50°C for all species.
- Avian thermoregulation in the heat: resting metabolism, evaporative cooling and heat tolerance in Sonoran Desert doves and quail
Highlighted Article: Species-level differences in heat tolerance may drive changes in desert bird communities as global temperatures continue to rise and heat waves become more frequent.
