[cobirds] Re: Merlin magic with vireos

Now maybe I will gripe. I was back at the same spot along Deer Creek this morning. After a little while a vireo began to sing again that sounded like a Plumbeous. And another began right away to sing back at it. Eventually I confirmed both as Plumbeous. I had Merlin Sound ID on again, and the first thing it registered for the vireo song was a Semipalmated Plover! Then came the Plumbeous ID, followed by Cassin's ID as the same nearby bird sang. A screen shot shows these. A little later, on a different recording it ID'd the same singing Plumbeous variously as Red-eyed Vireo, Blue-headed Vireo, and Plumbeous. Sigh...

This is not a Merlin gripe, but just a funny experience from this morning at Deer Creek.

Were I to follow the magician's lead, I had an unprecedented collection of vireos in one spot today near Deer Creek in JeffCo. It's fun anytime you have singing vireos in the fall, as some species do, making it easier to detect them,... if not to view them, But to have five different species singing in one tree in September is virtually unprecedented. Sadly, virtual was all it was.

There WERE two Plumbeous Vireos singing near to each other, as you can hear on the recording on the checklist. One was much closer to me, and is louder. And there WAS a Cassin's Vireo nearby, but it was silent for Merlin during my encounter. So that is two species. And while Merlin identified my prominent singing PLVI correctly sometimes, but also variously as a Cassin's, a Yellow-throated, a Red-eyed and a Black-whiskered Vireo. Hey, there's one new state bird in there!! All those were its proposed IDs for the one singing PLVI. Let the user beware for all rare bird reports via dear Merlin. This we know. Personally I can relate, as I have a hard time telling the song of the PLVI from that of the CAVI. 

At the same location last week Merlin reported a Water Rail. A Water Rail?!
