Mini-macaws are a loosely defined group of small-to-medium-sized macaw species within the tribe Arini. The term has no fixed taxonomic meaning and is principally used in aviculture to describe a small macaw belonging to one of a number of different genera, with overall length being the sole criterion for inclusion. Any macaw with an overall length (including the tail) of less than about 50 cm (20 inches) can be described as a "mini-macaw". Additionally, the "mini-" prefix may be added to the species name when describing the bird in question (e.g. "red-shouldered mini-macaw"). In the pet trade, the term can be used to suggest that the species in question is better suited as a companion parrot for owners with less space in their homes than would be required by one of the larger macaw species. 〔 ==Species== In aviculture the following are sometimes called mini-macaws:〔 *Chestnut-fronted, or severe macaw, ''Ara severa'' *Golden-collared macaw, ''Primolius auricollis'' *Blue-winged, or Illiger's macaw, ''Primolius maracana'' *Blue-headed macaw, ''Primolius couloni'' *Red-bellied macaw, ''Orthopsittaca manilata'' *Red-shouldered, or Hahn's macaw, ''Diopsittaca nobilis'' The red-bellied macaw and blue-headed macaw are typically only found in captivity in a zoo setting, or as part of a breeding program and are rarely kept as pets. 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「Mini-macaw」の詳細全文を読む スポンサード リンク
