Nocturnal and shy, this bird is much more often heard than seen. It can be found regularly sitting in the middle of a lonely gravel road where it will fly up in the headlights of a vehicle like a huge moth. Apparently it spends much of the winter in northern parts of its range in a state of torpor or hibernation concealed in rock piles. It catches insects at night in its gaping mouth by flying low over the desert floor. Its nest is a shallow depression on the ground, usually near a steep hill.
The four-digit banding code is COPO.
