The Badlands bighorn, ''Ovis canadensis auduboni'', also commonly known as Audubon's bighorn sheep, is an extinct subspecies of bighorn sheep of the northern Great Plains in North America. ==Former distribution== While the one common name refers to the Badlands region of the Dakotas, it inhabited a larger range that included Montana, Wyoming, Nebraska, South Dakota, and North Dakota. Some sources assert that the subspecies was hunted to extinction in the early 1900s. Others claim that the subspecies persisted as long as 1926. Some sources assert that it was not unique bighorn sheep subspecies but rather variation of the widespread Rocky Mountain Bighorn (''Ovis canadensi canadensis'').〔 Some later studies do not support the existence of the Badlands Bighorn as a distinct subspecies. Rocky Mountain bighorn have replaced the subspecies/variation in its former habitats. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Badlands bighorn」の詳細全文を読む スポンサード リンク
