The genus Psittacus was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. [3] The genus name is Latin for "parrot". [4] Linnaeus included all 37 of the then-known parrots in the genus and of these George Robert Gray designated the grey parrot (Psittacus erithacus) as the type species. [5] [6]
Carl Linnaeus redescribed the Alexandrine parakeet in 1766 as Psittacus eupatria. [9] The genus name Psittacula is a diminutive of the Latin word psittacus meaning "parrot", and the specific name eupatria (εὖπατριά) is derived from the ancient Greek eu-meaning "well" and patriá meaning "descent".

The species ability to track food (such as plants and plant parts including fruits, seeds, flowers, leaf buds, and sap) and switch diets determines the species ability to cope with environmental changes; it is a contributory factor to the population decline of the Timneh parrot. [10]

The grey parrot (Psittacus erithacus), also known as the Congo grey parrot, African grey parrot or Congo African grey parrot, is an African parrot in the family Psittacidae.

He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus tirica. [3] The type locality was subsequently designated as Brazil. [4] [5] The plain parakeet is now placed with seven other parakeets in genus Brotogeris that was introduced in 1825 by Irish zoologist Nicholas Aylward Vigors.
