The Kakapo is a large parrot species that lives on the island of New Zealand. By hand-raising the first group of chicks in captivity and encouraging females to lay more eggs, the Kkp Recovery Team hoped that overall chick production would be increased. Handbook of Australian, New Zealand and Antarctic birds: The habitat, food and feeding ecology of kakapo in Fiordland: a synopsis from the unpublished MSc thesis of Richard Gray, Nutrient composition of the diet of parent-raised kakapo nestlings, Intensive management of a critically endangered species: the kakapo, Agonistic display and social interaction between female kakapo (, Kakapo recovery: the basis of decision-making, A parrot apart: the natural history of the kakapo (, The challenge of supplementary feeding: can geometric analysis help save the kakapo, Seasonal changes in home range and habitat selection by kakapo (, Diet of kakapo in breeding and non-breeding years on Codfish Island (Whenua Hou) and Stewart Island. [74] During the winter of 1981, only females lighter than 1.5kg (3.3lb) were given supplementary feeding to avoid raising their body condition, and the sex ratio results in 1982 were close to parity, eliminating the male-biased sex ratios in the unrestricted feeding.
