Hunting is the practice of pursuing, killing or trapping any living organism, usually wildlife or feral animals, by humans for food, recreation, or trade. Animals may also hunt other animal species, but this is usually called predation. In present-day use, lawful hunting is distinguished from poaching, which is the killing, trapping or capture of the hunted species contrary to applicable law. The species that are hunted are referred to as game and are usually mammals and migratory or non-migratory gamebirds.
