Torpor is a short-term physiological state of decreased activity and metabolic rate that conserves energy. During torpor, a hummingbird can lower its body temperature and enter a restful state to conserve energy and survive a decrease in food supply. Shivering, hibernation, and burrowing into soil are not adaptations that hummingbirds are capable of doing, and fluffing their feathers is not a sufficient adaptation to conserve energy during a temporary food shortage.
