Hi, I didn't get a great shot of this bird because it didn't stay still for long! I found it in at Burleigh Falls, Ontario (just north of Peterborough) last week (August 8th) I only saw one but it was hanging around with Cedar Waxwings, Yellow Warblers and Yellow Rumped Warblers.
I'm not sure if it might be a Canada Warbler in some kind of transition because of the black parts on the breast.
Thanks for you help.
