It was way back in 1973 that the AOU lumped together the Myrtle Warbler and Audubon’s Warbler, creating the Yellow-rumped Warbler, or, more affectionately, good ol’ Butterbutts, much to the dismay of listers everywhere who lost a species from their various and sundry lists.  Now, as Nate of The Drinking Bird reports, the lump might be undone – we may have a split coming!  Listers, rejoice!
