Partial leucistic Cape May/Yellow Rump is back at Wakodahatchee - ID?

Last year at just about the same time, I had posted on here a warbler with some leucistic whites on his head and face...I was unsure of the type of warbler and posted here to try to ID him. We were split between Cape May and Yellow Rumped - but none of the shots were very good - badly backlit, high in the trees, partially blocked by branches, and from behind.
This time, I caught some pretty decent side profiles of the bird, and am posting them here in hopes that an ID of the type of warbler can be ironed down!

It looks like a Yellow-rumped Warbler.

That was my thought too - last year, it was from behind and not as identifiable, but this time the side markings were captured well enough to make me think it's a yellow-rumped.

my bird had more white in face-no yellow on sides i could see so possible female-yellow throat and rump with streaked chest

Cape May would have finer streaking that is more uniform in density across the breast than found on Yellow-rumped. This bird's streaking is concentrated towards the flanks and the streaks are more defused or blurry.

If you look at the edges of the flight feathers you can see that they are whitish rather than yellow/olive which you would find on Cape May.

These features point towards Yellow-rumped Warbler.
