My initial impression was Philadelphia, but looking closer I'm not so sure. The yellow seems like more of a wash and the facial pattern seems strong but is still giving me more Warbling vibes from the face alone. Philadelphias should have the yellow brightest on the throat, but this bird seems to have yellow brightest on the sides, and I'm not sure how much of the yellow on this bird is coming from leaf reflection.
I'm leaning toward Warbling on this one but it would be good to see more photos if possible.
