Saw this in southern ME yesterday. It was flitting about in the tree canopy (leaves just starting to fill in). A description of a female oriole seemed close, but the photos didn't seem as close a match. We have had a male Northern Oriole in the yard recently.
Looks like a Nashville warbler
Would it be a Nashville Warbler? http://www.bsbo.org/warbler-wednesday.html
Looks good for a Nashville Warbler
