The green-billed toucan (Ramphastos dicolorus ), or red-breasted toucan, is a near-passerine in the family Ramphastidae found in southern and eastern Brazil, Pantanal of Bolivia, eastern Paraguay and far north-eastern Argentina.
It is primarily found in the 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 toucans, weighing 265–400 g (9.3–14.1 oz) and measuring 40–46 cm (15.5–18 in) long in total. Its beak is one of the shortest of Ramphastos toucans at only about 10 cm (3.9 in) in length. Its breast is actually orange, with yellow at the sides. T
he 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.
