Taxonomy
The Nanday Parakeet, scientifically named Aratinga nenday, belongs to the family Psittacidae, which includes all true parrots, within the order Psittaciformes. Historically classified in the monotypic genus Nandayus, it was reclassified into the genus Aratinga based on mitochondrial DNA analysis, which showed it forms a monophyletic group with the Sun Conure (A. solstitialis), Jenday Conure (A. jandaya), and Golden-capped Conure (A. auricapilla). The species name “nenday” derives from the Guarani word for the bird, reflecting its cultural significance in its native range. A prehistoric relative, Aratinga vorohuensis, from the Late Pliocene in Argentina, suggests a long evolutionary history.
