What is "psittacus"

Psittacus is a genus of African parrots in the subfamily Psittacinae. It contains the two species: the Congo African grey parrot (Psittacus erithacus) and the Timneh African grey parrot (Psittacus timneh).

For many years, the Congo African grey parrot and Timneh African grey 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.

These parrots are found in the primary and secondary rainforest of West and Central Africa. They are one of the most intelligent birds in the world. They feed primarily on palm nuts, seeds, fruits, and leafy matter, but have also been observed eating snails. Their inclination and ability to mimic speech and other sounds have made them popular pets.
