Hi Andrew and all, Banding birds at the Fire Island Lighthouse, I encountered a few juncos with white wingbars. Invariably they were like Slate-colored hyemalis in other respects, whereas genuine aikeni White-winged Juncos are much larger and with significantly more white in the rectrices. In other words, it's a rare but regular variation among Slate-colored Juncos.

Over the years I've seen a few in NY that have them but otherwise look like Slate-coloreds. Today I had another I observered for awhile at Ward Acres Park in New Rochelle that sure looked good for White-winged Juco, but I always have Slate-coloreds with wing bars in the back of my mind. Any ideas?
