Common small toucan of rainforest canopy. The key field mark is the clear yellow belly that contrasts sharply with a dark breast. Usually seen in small groups at fruiting trees in clearings and at river edges. Like other toucans, sometimes rests on bare branches above the canopy; groups cross gaps in single file. Chuckling calls are woodpecker-like in quality. Similar to Black-necked Aracari in size, shape, and behavior, but lacks bands on belly, has a more colorful bill, and is more restricted to tall rainforest.
