Common pheasants were introduced in North America in 1773, and have become well established throughout much of the Rocky Mountain states (Colorado, Idaho, Montana, Wyoming, etc.), the Midwest, the Plains states, as well as Canada and Mexico. In the southwest, they can even be seen south of the Rockies in Bosque del Apache National Wildlife Refuge south of Albuquerque, New Mexico. It is now most common on the Great Plains. Common pheasants have also been introduced to much of northwest Europe, the Hawaiian Islands, Chile, Uruguay, Peru, Argentina, Brazil, South Africa, New Zealand, and Australia including the island state of Tasmania and small offshore islands such as Rottnest Island off Western Australia.
