New Zealand Freeflight Aviary

Hey, what species fly freely? Is that a Nestor meridionalis on the sign?

@Cyathea Species signed were North Island kaka, New Zealand wood pigeon, Tui, Red-crowned parakeet and North Island saddleback. I visited with my son and we both saw a New Zealand wood pigeon; and he said he saw a Tui. Neither of us saw any of the other species signed on this visit.
