Where it lives

Predator-free island and fenced sanctuaries, New Zealand

Ranges stay general on purpose. Witness never publishes a location that could help someone find an animal already under pressure.

What threatens it

  • Introduced predators
  • Disease
  • Low hatching success
  • Historic habitat loss

Life cycle

Kākāpō breed in summer and autumn, but only in years when native trees fruit heavily. On the southern islands that means the rimu: they breed when it fruits, roughly once every two to four years.

Field notes

Every passage carries the number of the source it came from. Nothing here is written from memory.

The kākāpō answers almost every expectation of a parrot with an exception. It cannot fly. It walks the night with an owl-like face and a waddling gait.Source 1

It is the heaviest parrot in the world, and possibly the longest-lived bird, with lives measured in many decades.Source 1

It is also the world’s only lek-breeding parrot: in breeding years, males boom across the hills for nights on end.Source 1

Kākāpō are taonga—a treasured species—to Ngāi Tahu, the principal Māori iwi of southern New Zealand.Source 1

Once found across New Zealand, kākāpō nearly vanished after human arrival brought hunting, habitat loss, and predators their ground-nesting lives could not survive.Source 1

Every kākāpō alive today lives wild on predator-free islands or in fenced sanctuaries, watched over by the Kākāpō Recovery programme.Source 1Source 2

Its keepers contend with low hatching success and the constant need for more predator-free habitat—and still the population has grown.Source 1Source 2

To witness the kākāpō is to learn how much care a species can require, and receive.Source 1

Did you know

A kākāpō cannot fly, but it climbs high into trees — and comes down in what one account calls a controlled plummet.
