However, there are 4 other genera of toucan, including Andigena (mountain toucans), Selenidera (dichromatic toucanets), Pteroglossus (araçaris), and Aulacorhynchus (green toucanets). Among the birds that toucans are related to are woodpeckers; however, they’re only distant relatives, so don’t expect toucans to start hammering palm trees with their bills.
