Quizplus · Accepted Answer

Torpor is a type of deep sleep that hummingbirds can enter into to conserve energy when food is scarce. It allows them to slow down their metabolic rate and avoid starvation during short-term absences of food resources. Shivering, hibernation, and burrowing are not adaptations that hummingbirds use to survive food shortages.
