WHAT IS THE RECTAL TEMPERATURE OF A HUMMINGBIRD IN FLIGHT?

The rectal temperature of a hummingbird in flight typically ranges between 40°C to 42°C (104°F to 107.6°F). These high temperatures are essential for maintaining their high metabolic rates, which are necessary for their rapid wing beats and energy-intensive hovering. This elevated body temperature allows them to sustain their active lifestyle while feeding on nectar and performing aerial maneuvers.
