 Eastern ground parrot

The eastern ground parrot ("Pezoporus wallicus") of Australia is one of only five ground-dwelling parrots in the world, the others being its closest relatives, the western ground parrot ("Pezoporus flaviventris"), the extremely rare night parrot ("Pezoporus occidentalis"), the somewhat closely related Antipodes parakeet ("Cyanoramphus unicolor"), and the unrelated highly endangered kakapo ("Strigops habroptilus") from New Zealand.The colouration of the three "Pezoporus" species and the kakapo is similar – yellowish green with darker barring, somewhat reminiscent of the head and back of the wild-type budgerigar.
