Kakapo the reason for its massive decline since the introduction of dogs, cats and mustelids (see "Conservation: Human impact"). The kakapo is the only species of flightless parrot in the world, and the only flightless bird that has a lek breeding system. Males loosely gather in an arena and compete with each other to attract females. Females listen to the males as they display, or "lek". They choose a mate based on the quality of his display; they are not pursued by the males in any overt way. No pair bond is formed; males and females meet only to mate. During
Kakapo annual health check and has their transmitter replaced. The Kakapo Recovery programme has been successful, with the numbers of kakapo increasing steadily. Adult survival rate and productivity have both improved significantly since the programme's inception. However, the main goal is to establish at least one viable, self-sustaining, unmanaged population of kakapo as a functional component of the ecosystem in a protected habitat. To help meet this conservation challenge, Resolution Island (20,860 ha) in Fiordland has been prepared for kakapo re-introduction with ecological restoration including the eradication of stoats. Ultimately, the Kakapo Recovery vision for the species is to restore the
