One of the handsomest wood-warblers, Bay-breasted Warbler’s breeding range is mainly across Canada, and, except for along the northern tier, is seen in the U.S. mostly during migration. Moved into genus Setophaga as of July, 2011. Fall migrants are difficult to tell apart from Blackpoll Warbler.

“Baypoll” Warbler – first winter
Bluff Point, Groton, CT
October 2, 2009 ©John Schwarz
This bird caused considerable deliberation because of the confusing similarity between first-winter Bay-breasted and Blackpoll Warblers. Outside opinions were sought, and out of ten responses there were six votes for Blackpoll and four votes for Bay-breasted. Upon close examination the undertail coverts appear to be white, and the feet appear to be orange – which would indicate a Blackpoll. (These two species are closely related; could they hybridize?)
