Chinese pheasant - It is a well-known gamebird, among those of more than regional importance perhaps the most widespread and ancient one in the whole world. The Common Pheasant is one of the world's most hunted birds; it has been introduced for that purpose to many regions, and is also common on game farms where it is commercially bred. Ring-necked Pheasants in particular are commonly bred and were introduced to many parts of the world; the game farm stock, though no distinct breeds have been developed yet, can be considered semi-domesticated. The Ring-necked Pheasant is the state bird of South Dakota, one of only three US state birds that is not a species native to the United States.
