Identify birds by sound, at scale.
BirdNET uses deep learning to recognize thousands of bird species from their vocalizations, powering research, monitoring, and citizen science around the world.
BirdNET is a collaboration between the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology and Chemnitz University of Technology.
What is BirdNET?
BirdNET is a research platform and family of tools that make it possible to detect, classify, and explore bird sounds using state-of-the-art neural networks.
From smartphone apps to large passive acoustic monitoring arrays, BirdNET supports workflows for birders, conservationists, and scientists.
