This was a new yard bird for me last September and I had a tough time with the ID, as the Vireos are all very similar. I luckily got enough shots to see the few distinguishing field marks that helped me ID it as a Philadelphia vs a Warbling Vireo (with a little help from my friends).

Glad you were able to ID it. Yes, those Vireos are tough to differentiate. We always have to look them up when we see them in the field.
Great picture.
