The Psittaciformes, including the parrots and their fossil relatives, are zygodactyl birds of which living species possess a robust bill specialised for breaking open seeds and nuts. Known stem parrots from the Eocene of Europe and India include the Quercypsittidae and Psittacopes lepidus. Psittacopes lepidus, from the Messel Formation of Germany, had a bill that was much less hooked and robust than that of living parrots (the beak of Quercypsittidae is unknown) (Mayr 2009).
Within the crown group, recent phylogenetic studies agree that a clade of large New Zealand parrots including the kakapo Strigops habroptilus, kaka Nestor meridionalis and kea N. notabilis represents the sister group to other living parrots. The species of Nestor are largely brown or green parrots with a long, strongly curved upper mandible.
