A parrot apart: The natural history of the kakapo (Strigops habroptilus), and the context of its conservation management

Abstract

Since the last review of kakapo biology, published 50 years ago, much has been learnt as a result of the transfer of all known individuals to offshore islands, and their intensive management to increase adult survival and productivity. This review summarises information on a diversity of topics, including taxonomy, plumage, moult, mass, anatomy, physiology, reasons for decline in distribution, present numbers and status, sex ratio, habitat, home range, foraging activities, diet, voice, breeding biology, nesting success, sexual maturity, and adult survival. In addition, those kakapo attributes that compromise its long-term survival in present-day New Zealand are discussed, along with management practises developed to overcome these problems. © The Ornithological Society of New Zealand, Inc. 2006.
