Description
The Common Poorwill is a small, nocturnal bird known for its superb camouflage, allowing it to blend seamlessly with its surroundings. It is unique among birds for its ability to enter torpor, a state similar to hibernation, to conserve energy during cold periods or food scarcity. This ground-dwelling species is primarily active at dusk and dawn, hunting insects on the wing.
