It does not apply to BirdNET for now, does it?For what it's worth, if anyone has a recording from the Merlin app where they are certain the ID that Merlin is giving is incorrectly, there is a way you can help with improving the app.
Upload the audio to an eBird list OR onto Macauley Library, and let myself or any other annotator for Merlin know and we can get it added to the training data to improve the system. (Caveat: should be "normal" songs & sounds, no nestlings sounds or obscure rarely heard vocalizations.) We've now got the ability to manually bring recordings into our annotation system, so while this wasn't possible last year it is now!
EDIT: Do clear recordings given by a known species that were left unidentified also count (wrt Merlin, not BirdNET)?
