A rooster, also known as a cockerel or cock, is a male gallinaceous bird, usually a male chicken (Gallus gallus).
Mature male chickens less than one year old are called cockerels. The term "rooster" originates in the United States, and the term is widely used throughout North America, as well as Australia and New Zealand. The older terms "cock" or "cockerel", the latter denoting a young cock, are used in the United Kingdom and Ireland.
"Roosting" is the action of perching aloft to sleep at day, which 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, a rooster will often sit on a high perch, usually 0.9 to 1.5 m (3 to 5 feet) off the ground, to serve as a lookout for his group. He will sound a distinctive alarm call if predators are nearby.

The chicken (Gallus gallus domesticus) is a domesticated fowl, a subspecies of the Red Junglefowl. As one of the most common and widespread domestic animals, with a population of more than 24 billion in 2003, there are more chickens in the world than any other species of bird. Humans keep chickens primarily as a source of food, consuming both their meat and their eggs.
The traditional poultry farming view of the domestication of the chicken is stated in Encyclopædia Britannica (2007): "Humans first domesticated chickens of Indian origin for the purpose of cockfighting in Asia, Africa, and Europe. Very little formal attention was given to egg or meat production... " Recent genetic studies have pointed to multiple maternal origins in Southeast, East, and South Asia, but with the clade found in the Americas, Europe, the Middle East and Africa originating in the Indian subcontinent. From India, the domesticated chicken was imported to Lydia in western Asia Minor, and to Greece by the fifth century BC. Fowl had been known in Egypt since the mid-15th century BC, with the "bird that gives birth every day" having come to Egypt from the land between Syria and Shinar, Babylonia, according to the annals of Thutmose III
