These sounds also seem to function in species recognition, as similar species of toucans that live in the same habitat have unmistakably different calls.

Toucans are among the noisiest of forest birds their repertoire includes loud barks, bugling calls, and harsh croaks. In foraging, toucans form large associations of two or more species that search for fruiting trees. Toucans are also predators on the contents of songbird nests, consuming both eggs and nestlings.
