Not the most conventional application for self-hosting, but thought it might make for a fun weekend project for someone.
BirdNET-Pi is built off the back of Cornell University’s BirdNET Sound ID neural network model (https://birdnet.cornell.edu/). It can be used to classify what birds are in your vicinity by listening to their calls.
In case y’all haven’t seen it: you can run similar software in a docker container and connect it to a standard security camera stream to get audio.
