This definitely looks like an Orange-crowned Warbler to me.
It has that general greenish-brown wash, even in the wings. Shows a hint of a lighter supercilium, and the broken eye ring that Nashville does not show. Also, the point against Nashville is the lack of yellow wash (or any hint thereof) in the belly.
I can be wrong, I'm no expert, but this is my opinion.
Cheers & good birding,
