A migrating Acadian and an eBird Hotspot first for this species. This bird was recorded and the audio is attached. An initial heads-up regarding one or both of these birds being ACFLs and not YBFLs came from Jim Pawlicki via Sal and later confirmed by Jay McGowan and Chris Wood. Comments from Jay McGowan: "I think these look good for Acadian. The head seems pretty big and flat, and particularly the call note seems pretty classic for Acadian as well, a simple peaked overslur. I agree they are on the yellow end for that species, but not out of range of variation I think."
