Rose-ringed parakeet 
(Vẹt cổ hồng, Psittacula krameri), also known as the ringneck parrot (in aviculture) or the Kramer parrot
 the specific krameri commemorates the Austrian naturalist Wilhelm Heinrich Kramer.

The rose-ringed parakeet (Psittacula krameri) is a medium-sized parrot in the genus Psittacula, of the family Psittaculidae. 
The bird has a disjunct native range in tropical northern Africa and the Indian subcontinent, introduced to other parts of the world through trade.

Psittaciformes comes from the Ancient Greek word ψιττακός (psittakós) meaning "parrot" combined with the Latin suffix -formes (shape/form), essentially meaning "parrot-shaped" or "of the parrot form," referring to the bird order containing parrots, cockatoos, and macaws. 

The family name Psittaculidae comes from the Latin psittacus (parrot), which itself derives from the Ancient Greek word ψιττακός (psittakós), also meaning "parrot" with the suffix -ula indicating "little" or "diminutive," essentially meaning "little parrots" or "parakeets". It refers to Old World parrots like parakeets and lories. 

Psittacula is a Latinized term meaning "little parrot" or "parakeet," derived from the Latin psittacus (parrot), which itself comes from the Ancient Greek word psittakós (ψιττακός) for parrot, plus the diminutive suffix -ula. The name of the genus is a diminutive of the Latin word psittacus for a "parrot".
