Cock in the nature

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,[1] and the term is widely used throughout North America, as well as Australia and New Zealand.[2] The older terms "cock" or "cockerel", the latter denoting a young cock, are used in the United Kingdom and Ireland.[3]
