Merlin very frequently “detects” birds that are not actually there. As discussed in many threads, you should not use auto-recognizers (including iNat’s CV) to ID beyond what you can verify (with assistance from knowledgeable human identifiers, if needed).
Merlin is a great tool, but overreliance is causing a lot of data quality issues that are frustrating eBird reviewers in particular. The good thing about Merlin is it creates an audio file that can be verified by others if you are unable to make a field ID. And then those audio files can be edited (some relevant info in this thread) and uploaded to citizen science platforms like iNat and eBird.
