This is a very aptly-named species of ramphastid: the face and underparts of the Saffron Toucanet are predominately yellow, and the upperparts are yellow olive. The appearance of this toucanet is so distinctive that traditionally is was classified in the monotypic genus Baillonius. Recent phylogenetic analyses based on DNA sequence data, however, demonstrate that the Saffron Toucanet is a distinctively-plumaged species of aracari (Pteroglossus), and is most closely related to Green (Pteroglossus viridis) and Lettered aracaris (Pteroglossus inscriptus). The Saffron Toucanet is restricted to humid forests of southeastern Brazil, northeastern Argentina, and eastern Paraguay, and usually is uncommon. Despite its distinctive appearance, the Saffron Toucanet has not been well-studied, and little is known about its natural history. Saffron Toucanets often are quiet, even secretive; they forage for fruit, and perhaps young birds and eggs, in mid levels and the canopy of forest.
