Oh I'm not sure.  What is the most common?
Psittacus
Psittacus is a genus of African parrots in the subfamily "Psittacinae". It contains the two species: the grey parrot ("Psittacus erithacus") and the Timneh parrot ("Psittacus timneh").
For many years, the grey parrot and Timneh parrot were classified as subspecies; the former as the nominate, the latter as "P. e. timneh". However, in 2012 the taxa were recognized as separate species by BirdLife International on the basis of genetic, morphological, plumage and vocal differences.
Parrot
Parrots, also known as psittacines , are birds of the roughly 393 species in 92 genera that make up the order Psittaciformes, found in most tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia.
