 | | Refuges have been established for big game (e.g., bison, bighorn sheep, and elk), small resident game, waterfowl, and colonial nongame birds (e.g., pelicans, terns, and gulls). |
 | | Although the main purpose of the refuge system is to ensure survival of wildlife by providing suitable cover, food, and protection from humans, many refuges permit hunting and fishing in season and other recreational activities such as hiking, boating, and swimming. |
 | | Refuges have been established by private individuals and societies (the Nature Conservancy and the National Audubon Society are notable for their pioneering conservation work) and by all levels of government. |
