Beautiful photo! If you look at the crissum (under the tail) you'll see that it's yellow. That means that this is a winter-plumage Palm Warbler That's the other common wintering warbler in the Florida penisula. The Yellow-rumped Warbler has a white crissum and usually has a white throat (at least in Florida where the "Myrtle" race over winters).
My pleasure! I used to live in Tampa in the early 1990s and I was always amazed by the numbers of Palm Warblers and Yellow-rumped Warblers that I would see around town. They're both wonderful warblers to have around.
