Their calls are largely croaks and yelps. The aracaris are composed of 11 species and are smaller and more slender. They have black or dusky green backs, crimson rumps, and are usually black on the head and neck. Their long bills are black and ivory, wholly ivory, or mainly fiery red. Aracaris have calls that are sharp and high-pitched.
Toucanets encompass two genera.
The seven species of Aulacorhynchus are small to large with mainly green plumage. Their calls are unmelodious croaks, barks, and dry rattles. The five species of Selenidera have more variable plumage and the sexes differ conspicuously in color. The last group of toucans is the four species of mountain toucans in the genus Andigena .
