Blue-rumped parrot (Vẹt đuôi ngắn, Psittinus cyanurus)

The blue-rumped parrot (Psittinus cyanurus) is found in the very southern tip of Myanmar, peninsular Thailand, Malaysia, Borneo, Sumatra and nearby islands.

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. 

Psittinus is derived from the Latin word psittacus (meaning "parrot"), which itself comes from Ancient Greek psittakós meaning parrot.

Cyanurus comes from Ancient Greek roots: "kyanos" (κύανος) meaning "dark blue" and "oura" (οὐρά) meaning "tail".
