“Cock” is in general use as the name for a male of other species of bird, for example “Cock sparrow”. “Roosting” is the action of perching aloft to sleep at night, and is done by both sexes. The rooster is polygamous, but cannot guard several nests of eggs at once. He guards the general area where his hens are nesting, and will attack other roosters that enter his territory. During the daytime, he usually sits on a high perch, usually 3–5 feet off the ground to serve as a lookout for his flock. He will sound a distinctive alarm call if predators are nearby.
