The Common Poorwill is the smallest of the "nightjars" in North America, and is considered the western counterpart of the eastern Whip-poor-will. The Hopi name for the Common Poorwill means "the sleeping one", as they are the only bird known to hibernate. Some remain throughout the year in the Southwestern U.S., but in cold weather, they enter a hibernating state with a lowered body temperature, heartbeat, and rate of breathing. They may stay in this state for days or weeks at a time.
