Kakapo Codfish / Whenua Hou and Anchor, where they are closely monitored, and Little Barrier / Hauturu Island is being trialled as a third home for the species. The common English name "kakapo" comes from the Māori "kākāpō", from "kākā" ("parrot") + "pō" ("night"); the name is both singular and plural. "Kākāpō" is increasingly written in New Zealand English with the macrons that indicate long vowels. The kakapo was originally described by English ornithologist George Robert Gray in 1845 and named "Strigops habroptilus". Its generic name "Strigops" is derived from the Ancient Greek "strix", genitive "strigos" "owl", and "ops" "face", while
Kakapo non-dispersive sex when food is plentiful. A female kakapo will likely be able to produce eggs even when there are few resources, while a male kakapo will be more capable of perpetuating the species when there are plenty, by mating with several females. This supports the Trivers–Willard hypothesis. The relationship between clutch sex ratio and maternal diet has conservation implications, because a captive population maintained on a high quality diet will produce fewer females and therefore fewer individuals valuable to the recovery of the species. The beak of the kakapo is adapted for grinding food finely. For this reason, the
