Bob, I didn't even consciously notice there were 2 types of Brewster's Warblers until I saw your message. My Brewster's Warbler was the white-winged variety. (My notes to myself indicate the wing-bars were white, as does my memory. See below.) Again, in all respects apparent to me, it was exactly the same as the topmost Brewster's Warbler depicted in the (old) Natl Geo Guide. It had nowhere nearly the amount of yellow in the breast as in the 2nd picture down. For the record, here are my entire on-site notes: "Brewster's Warb 5/10/99 3:40 - 4:00 Yellow crown Black eye-line (eye to bill only) throat and breast (below eyeline) white except a small wash of yellow in breast Back & Wings gray wing bars dull white (2) Call: Blue-wg call [2 wavy lines to show the two-toned song] Tail gray top white under" Your message does seem to reinforce that my Brewster's was in Balto Co some of the time but mostly in Carroll Co.
