Pyrilia
Pyrilia is a genus of parrots in the family Psittacidae. It was recently split from the now- monotypic Pionopsitta, and then briefly moved to Gypopsitta. But as Pyrilia was published a few months before Gypopsitta, the latter is a junior synonym.
All are relatively short-tailed parrots that are restricted to forests in the Neotropics. Their head or face contrasts clearly with the mainly green body, and they have a brownish or olive patch on the chest.
