Rooster

A rooster, also called a cock or chanticleer is a male chicken , the female being called a hen. Immature male chickens of less than a year's age are called cockerels. The oldest term is "cock", from Old English coc. It is sometimes replaced by the synonym: "cockerel" (which properly refers to a young male chicken) in the United Kingdom, and almost always by "rooster" (a relative neologism) in North America and Australia. "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 actually 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 who enter his territory. During the daytime, he often sits on a high perch, usually 4–5 feet off the ground, to serve as a lookout for his flock. He will sound a distinctive alarm call if predators are nearby.
