My FAVORITEST Parrot - the Kakapo Parrot (or Owl Parrot) of New Zealand!! It is the heaviest parrot in the world. Two other features make it extraordinary; it is also the ONLY flightless parrot and the ONLY nocturnal parrot known to man. The Kakapo Parrots, are critcally endangered. As of November 16, 2009, there are 124 Kakapo Parrots in the wild.
