Pteroglossus aracari (Linneaus 1758) is the extant black-necked aracari, a type of toucan. Toucans are restricted to the New World. Like the Old World hornbill, the bill is deep and the nares are dorsal. Wikipedia reports that toucans are related to woodpeckers. Not true. Here toucans are related to hornbills derived from Cyrilavis. Like the unrelated parrot and woodpecker, digit 4 is oriented posteriorly by convergence.

Buceros hydrocorax (Linneaus 1758) is the extant rufous hornbill. All hornbills are restricted to the Old World. Most studies find toucans and hornbills unrelated, similar only by convergence. The present study finds they are sister taxa. The separation of toucans and hornbills had to happen by the Albian (Latest Early Cretaceous, 100 mya) based on the distance between the two continents at that time and the fact that these taxa are not long distance flyers.

Psilopogon pyrolophus (S. Müller 1836; 28 cm in length; SE Asia) is the extant fire-tufted barbet. Like the related toucans + hornbills this frugivore uses tree cavities to nest and raise chicks in. Since this bird is from the Old World and related toucans are restricted to the New World, Psilopogon must have lived before the appearance of the Atlantic Ocean, in the Early Cretaceous.

Phaethon rubricauda (Boddaert 1783; 60-70cm long sans tail feathers) is the extant red-tailed tropicbird. Here it nests with barbets. This is an ocean-going soaring bird convergent with terns like Thalasseus.
