The kakapo has a well-developed sense of smell, which complements its nocturnal lifestyle. It can distinguish between odours while foraging, a behaviour reported in only one other parrot species. The kakapo has a large olfactory bulb ratio (longest diameter of the olfactory bulb/longest diameter of the brain) indicating that it does, indeed, have a more developed sense of smell than other parrots. One of the most striking characteristics of the kakapo is its distinct musty-sweet odour. The smell often alerts predators to

This is in part due to the absence of stoats and ferrets. Certain coastal areas of this park are breeding areas for the endangered yellow-eyed penguin. Weka, a flightless and curious bird species, can only be found on offshore islands. In the 1970s, kakapo were found in the Tin Range at a time when it was thought that the species was nearly extinct. The kakapo have been transferred to nearby Codfish
