Western Warbling Vireo, Custer County

[Mary Kay Waddington]

Birding in the foothills of the Sangre de Cristos, the Western Warbling Vireos have started to rev up.  Several of them, singing all over the place.  The strange thing is that Merlin does not recognize them at all.  Several times there was one singing loudly right next to me and Merlin was a blank.  In the "explore" portion of Merlin it comes up with the calls, and when I play that call, the Vireos come right down to investigate.  But in the ID section, nada.  Has anyone else experienced this?  Is it possible that when the species split they accidentally deleted the Western from the ID section?
