Most of us just call a junco a junco. Others feel more comfortable using the AOU name Dark-eyed Junco. Others like to be more specific and call them Slate-colored Juncos. To the best of my knowledge no one is contemplating splitting Dark-eyed Junco. But remember that Pink-sided Juncos are reported most years in this region. Sometimes Oregon Juncos also. As for Yellow-rumped Warblers. Many of us are in the age group that learned Myrtle Warbler before the species were lumped and we still use that name. Others of us want to be more specific about the kind of Yellow-rumped Warblers seen. But remember again that several years ago a few Audubon's Warblers made it to this region for the first confirmed records in Maryland. Similarly, before Northern Oriole was split, we still called our orioles Baltimores. Bob Ringler
