Hummingbirds survive cold nights by entering torpor, a deep sleep-like state where their heart rate drops from 1,200 bpm to 50, breathing nearly stops, and body temperature falls to 10-20°C, saving up to 95% of their energy; they remain motionless for hours until warmth returns, then rapidly revive within minutes to resume flight and feeding.

Hummingbird Torpor: Survives Cold Nights! 🐦 Energy Saving Modeインデックス作成:
Hummingbirds enter torpor—a deep sleep-like state—when night temperatures drop, slashing their heart rate from 1,200 bpm to 50, breathing nearly stops, and body temperature plunges to 10–20°C, saving up to 95% energy. They stay still for hours, reviving in minutes as the sun rises, revving metabolism back to 1,200+ bpm for flight and feeding. Nature’s tiny power saver!
