Will hummingbirds tolerate high temperatures due to climate change? Many studies look at heat tolerance during rest, but we study heat tolerance during hovering. Hummingbirds produce extra heat while hovering that must be dissipated to prevent overheating. Our previous work shows that in warm temperatures hovering hummingbirds cannot cool themselves. In this study we explore whether or not hummingbirds select perches in cool places between hovering bouts to facilitate heat loss.
