Aratinga is a genus of South American conures. Most are predominantly green, although a few are predominantly yellow or orange. They are social and commonly seen in groups in the wild. In Brazil the popular name of several species usually is Jandaia, sometimes written as Jandaya in the scientific form.
Many species from this genus are popular pets, although being larger than the members of the genus Pyrrhura, they need a sizable aviary to thrive.
The taxonomy of this genus has recently been resolved by splitting it in four genera as the genus as previously defined was paraphyletic. The species of the Aratinga solstitialis complex, were retained in this genus, while other former Aratinga species were moved to Eupsittula (brownish-throated species), Psittacara (pale-beaked species) and Thectocercus (blue-crowned parakeet). Furthermore, the closely related nanday parakeet (Aratinga nenday) and the dusky-headed parakeet (Aratinga weddellii) are placed in this genus. The nanday parakeet was previously placed in its own genus based on the differences in coloration and elongated upper mandible, but this was not supported by phylogenetic studies that showed a close relationship with the solitarius complex species.
