Cock is a common term used in zoology to refer to male birds, particularly those of the chicken species (Gallus gallus domesticus).

In a broader sense, cock may also describe the adult male of several other bird species, such as pheasants, ducks, and geese.

Within the context of gamefowl or cockfighting, the term cock specifically refers to a mature rooster trained for competitive fighting.

It is important to note that using the term cock in a colloquial or slang context may imply a vulgar or explicit meaning, unrelated to its zoological or avian references.
