Post-gardening and pre-Stanley Cup final-viewing, I was able to dig up a
very informative little essay on Blue-winged x Golden-winged Hybrids in
the Dunn & Garrett book on Warblers (Peterson Field Guide series).  The
Brewster's Warbler observed this morning east of Aurora was a male F2
backcross, best shown in the photo on pg. 141 of that book.  There are
several good plates on pg. 49, though the Brewster's 2nd generation
backcross male shown there has two distinct wing bars, unlike the
variant observed east of Aurora today.

My earlier post has more details and directions.
