The Red-breasted Toucan is found in southern and eastern Brazil, eastern Paraguay and far north-eastern Argentina. It is primarily found in Atlantic Forest.
It is one of the smallest species of toucans, weighing 350 gm. Its beak is one of the shortest of toucans at 10 cm in length. The Red-breasted Toucan derives its name from the large area of red feathers, which are really on the abdomen. Its breast is actually orange, with yellow at the sides. The beak is mostly pale greenish-horn, leading to its alternative common name, the Green-billed Toucan.
