The Cacophony Project has arrived at Sanctuary Mountain Maungatautari and has been making regular audio recordings at one of the high points in the sanctuary since October 2018. The project aims to greatly improve the ability to eliminate pest predators throughout New Zealand and monitor the effects on bird life that this brings. It is well known that eliminating the last few pests using traditional techniques is difficult. The Cacophony Project envisages that this can be overcome by using lures such as sound and light to attract the last of these pests to one of numerous locations where they can be automatically identified using thermal cameras and artificial intelligence before beginning killed in a safe and humane manner.
