Hovering in the heat: effects of environmental temperature on heat regulation in foraging hummingbirds

Hovering in the heat: effects of environmental temperature on heat regulation in foraging hummingbirds

At high temperature (greater than 40°C) endotherms experience reduced passive heat dissipation (radiation, conduction and convection) and increased reliance on evaporative heat loss. High temperatures challenge flying birds due to heat produced by wing muscles. Hummingbirds depend on flight for fora...
