An interesting #android app appeared in F-Droid: whoBIRD, that tries to recognize #bird species by sound. It uses well-known #birdNET model, but contrary to official birdNET app, whoBIRD works offline – a very welcome feature, as internet access in the woods or among bogs usually leaves much to be desired.
I have yet to test it on real #birds, but so far it has properly recognized “human whistle” and ”machinery sounds” ;)
