The spruce trees next to my house have been alive with small birds this week. Those present include goldfinches, olive sided flycatchers, blackburnian warblers, myrtle warblers, and these two that I’ve been unable to identify. I tried Roger Tory Peterson, Sibley, and the Audubon Society books to no avail. The images are not very good quality (handheld @~250mm and 20 yards), but I’m hoping someone can help identify these two (warblers?). Thanks in advance for your thoughts.
