Kakapo the presence of kakapo. As a nocturnal species, the kakapo has adapted its senses to living in darkness. Its optic tectum, nucleus rotundus, and entopallium are smaller in relation to its overall brain size than those of diurnal parrots. Its retina shares some qualities with that of other nocturnal birds but also has some qualities typical of diurnal birds, lending to best function around twilight. These modifications allow the kakapo to have enhanced light sensitivity but with poor visual acuity. The skeleton of the kakapo differs from other parrots in several features associated with flightlessness. Firstly, it has the smallest
Kakapo areas of Fiordland. Kakapo seem to have preferred broadleaf or mountain beech and Hall's tōtara forest with mild winters and high rainfall, but the species was not exclusively forest-dwelling. All kakapo that were transferred to predator-free islands in the last decades have adapted well to any changes in environment and food plants. It seems that the kakapo – like many of New Zealand's bird species – has evolved to occupy an ecological niche normally filled by various species of mammal (the only non-marine mammals native to New Zealand are ). The kakapo is primarily nocturnal; it roosts under cover in
