What is BirdNET?
BirdNET is a collaborative research initiative between the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology and the Chair of Media Informatics at Chemnitz University of Technology. It employs Artificial Intelligence (AI) and machine learning techniques to enable the identification of birds solely through their sounds. The primary goal is to support experts and citizen scientists in the crucial tasks of monitoring bird populations and contributing to their conservation.
Operating as both a citizen science platform and a powerful analysis tool for extensive audio collections, BirdNET is accessible across various hardware and operating systems, including smartphones (Android and iOS apps), web browsers, and even research computing setups. The core technology relies on an artificial neural network trained to recognize avian sounds. It analyzes audio recordings, identifying the most probable species present, often utilizing location and date information (via smartphone GPS) to enhance accuracy. BirdNET currently identifies approximately 3,000 common bird species worldwide, with ongoing development to expand its capabilities.
