I've been a user of BirdNet (also from Cornell, but apparently a different group?), looking forward to checking out Merlin. With Birdnet you have to record a sound, pick out the specific portion of the audio and click identify.
Another good one is SongSleuth[1] - recently recommended to me by Nathan Pieplow because it has a "pre-record" buffer so you can hit record as or immediately after you hear a bird and it captures a few seconds before that instead of having to run Merlin continuously waiting for the bird to call next.
I've tried setting it up with the birdnetlib package but had trouble getting it running with a model and pack that was for my region. The default model for birdnetlib is in Europe.
