A parrot was a type of bird native to Earth.
According to K9 Mark II, Parrots were of the family Psittacidae and were often colourful with short, down-curved hooked bill grasping feet and a raucous voice. They were most commonly found in the tropics and ate fruits and seeds. Parrots were also commonly kept as cage birds. (AUDIO: The Sands of Life)
In 1970s London, the Third Doctor and Brigadier Lethbridge-Stewart encountered parrots at a zoo which were in a frenzy. They broke out of their cage and attacked the Doctor and the Brigadier, but the two men escaped by diving into a pool of penguins, which also attacked them. The parrots then flew off towards the town to wreak havoc there — and oddly, were never seen nor mentioned again. (COMIC: The Arkwood Experiments)
