This list of birds of Yellowstone National Park includes every wild bird species reported in Yellowstone National Park in the last 50 years. Since its creation in March, 1872, 318 species of birds have been documented in the park. Only birds that are considered to have established, self-sustaining, wild populations in Yellowstone are included on this list. This means that birds that are considered probable escapees, although they may have been sighted flying free in Yellowstone, are not included. This list is presented in taxonomic order and follows ''The Check-list of North American Birds'' (7th edition, 1998) published by the American Ornithologists' Union. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account.〔(【引用サイトリンク】title=The AOU Check-list of North American Birds, 7th Edition )〕 ==Legend== As listed in the Checklist of the Birds of Yellowstone National Park:〔 * I - Introduced species that are not native to North America, but were brought to this continent by humans. * B - Breeders, species known to have nested or produced dependent young in Yellowstone in recent years. * * - Less than 20 documented records of this species exist in Yellowstone over the last 50 years. * + - The Yellowstone Center For Resources welcomes additional information regarding this species. * N - Neotropical migrants, birds known to spend the summer season in temperate North America and winter in the Neotropics (i.e., the area of the New World that lies south of Central Mexico and Cuba and north of northern Argentina and southern Brazil). 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「List of birds of Yellowstone National Park」の詳細全文を読む スポンサード リンク
