The first fossil barbet (Aves, Ramphastidae) from Siberia
Journal of Ornithology, 2019Barbets are arboreal birds, inhabiting mainly tropical forests west of the Wallace’s Line. Fossil remains of barbets are extremely scarce. Until recently, only two species of barbets were described from the early and middle Miocene of Europe and several other undescribed fragments were mentioned in the literature.

The Curl-crested Aracari Pteroglossus beauharnaesii Wagler, 1832 is one of the most remarkable species in the family Ramphastidae. Among other distinctive plumage traits, its modified curly, shiny black crown feathers are unique in the family and are modified to an extent not found in any other living bird species (Brush 1967; Short & Horne 2002 ...

Introduction. The Andean toucan Andigena laminirostris (Ramphastidae) is an important component of the avifaunal biodiversity of western Ecuador and Colombia. Most of their populations are threatened directly or indirectly by the development of productive human activities that generally harm their habitats. Objective.

The Gould’s Toucanet Selenidera gouldii (Natterer, 1837) (Aves: Ramphastidae) as a monotypic species
ZootaxaThe Gould’s Toucanet Selenidera gouldii (Natterer, 1837) occurs mainly in eastern Amazonia, with a geographically isolated population in the northeast Brazilian state of Ceará. Based on two male specimens from the latter population that appeared to have a smaller body and bill with a relatively large black patch, Pinto & Camargo (1961) described ...

As all the anatomical conditions are not present to permit any movement between the cranial segments, the bill aperture and closure by the rotation on the quadrato mandibular joint is, in Ramphastos , the only action studied in relation to muscles organization and bone architecture by torques analysis.
