| Semnornis ramphastinus (Jardine, 1855) |
The Toucan Barbet, Semnornis ramphastinus, is a distinctive Neotropical bird.
It often has been united with the other barbets in the Capitonidae. However, DNA studies[citation needed] have confirmed that this arrangement is paraphyletic. The toucans are more closely related to the "true" New World barbets than the latter are to the genus Semnornis or barbets of the Old World. As a result, the barbet lineages are again considered distinct families; the present species together with the Prong-billed Barbet now form a separate family, Semnornithidae.
The Toucan Barbet is unusual amongst frugiverous birds in that it breeds cooperatively, with several helpers aiding the dominant breeding pair with incubation and raising the young.[2]
