Kākā are threatened by habitat destruction and predation by introduced species including stoats, which kill females on eggs, and other mammals. Introduced wasps and possums compete with Kākā’s for honeydew, a high-energy resource required by Kākā for successful breeding. A more recent danger faced by Kākā fledglings is window strikes, causing injury or death to many birds each year.
The WPT has joined with local and regional partners to support intensified feral predator control, and rehabilitation, release and tracking of injured Kākā on Waiheke Island, a citizen science project assessing the effectiveness of window markers in preventing bird collisions, and with volunteers, radio-tracking captive-bred birds released at Cape Sanctuary to better understand movements and survival.
