The Cacophonometer is the easiest way to measure how bird populations are changing. This device makes periodic sound recordings and uploads them to the cloud, noting the time and location. These recordings will be analysed to detect the volume of birdsong and how it changes over time, giving you an objective measure of the impact of predator control or reforestation.
This device has been developed by the team at The Cacophony Project. A proportion of the proceeds will be be donated to this not for profit group to further develop their technologies and help make New Zealand predator free.
