Question

What thermoregulation strategy does a hummingbird rely on to keep from getting too cold?

1) Hibernation
2) Panting
3) Shivering
4) Torpor

Answer 1

Hummingbirds rely on torpor as a thermoregulation strategy to keep from getting too cold.

Step-by-step explanation:

A hummingbird relies on the thermoregulation strategy of torpor to keep from getting too cold.

Torpor is a state of decreased activity and lowered metabolic rate, similar to hibernation, but on a shorter timescale. It allows hummingbirds to conserve energy during the coldest parts of the day when they consume more energy to maintain their body temperature.

This strategy is crucial for hummingbirds because their high metabolic rates require them to continuously consume large amounts of energy to power their flight.
