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 long and the distal elements are disproportionately short. The pectoral musculature of the kakapo is also modified by flightlessness. The pectoralis and supracoracoideus muscles are greatly reduced. The propatagialis tendo longus has no distinct muscle belly. The sternocoracoideus is tendinous. There is an extensive cucularis capitis clavicularis muscle that is associated with the large crop. Because kakapo passed through a genetic bottleneck, in which the world population was reduced to 49 birds, they are extremely inbred and have low genetic diversity. This manifests in lower disease resistance and fertility problems: 40% of kakapo eggs are infertile. Beginning in 2015, the
