The mandible always is black, and the maxilla is mostly yellow, but the extent of the yellow varies across subspecies. Emerald toucanets are as quick to learn tricks as cockatoos.

These subspecies can be divided into up to 4 groups which sometimes are recognized as separate species; see also Related Species.
