The green-billed toucan (''Ramphastos dicolorus''), also known as the red-breasted toucan, is found in southern and eastern Brazil, Pantanal of Bolivia, eastern Paraguay and far north-eastern Argentina. It is primarily found in Atlantic Forest. Overall, it is fairly common, and therefore considered to be of least concern by IUCN.〔 It is one of the smallest species of ''Ramphastos'' toucans, weighing 265–400 grams (9.4–14.2 oz.) and measuring 40–46 cm (16–18 in) long in total.〔http://www.nashvillezoo.org/piciformes/ramphastidae.htm〕 Its beak is one of the shortest of ''Ramphastos'' toucans at only about 10 cm (4 in) in length. Its breast is actually orange, with yellow at the sides. The beak is mostly pale greenish-horn, leading to its common name. In aviculture, their requirement of spacious cages, a high fruit diet and sensitivity to hemochromatosis (iron storage disease) make them difficult to maintain for novice keepers. ==References== == External links == *(Extensive Gallery on Toucans ) *(List of Toucans ) *(Toucan videos ) on the Internet Bird Collection 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「Green-billed toucan」の詳細全文を読む スポンサード リンク
