Jennifer, As I look at your photos of the Wilson's Warbler, it appears to me that the dark "necklace" I see is really an area where feathers are missing. The dark area is the under feathers in that area, the yellow feathers that should be covering those dark feathers are gone for some reason. When this bird molts again, I would guess it will look just like all other Wilson's Warblers. Interesting find.
