I've been quite puzzled at the many reports coming in to ebird of
yellow-rumped warblers, which are pretty unusual this early in the
season. This ebird checklist <https://ebird.org/checklist/S95399246> has
a picture of a supposed yellow-rumped warbler, which I think is really a
Cape May Warbler.
I sometimes forget that Cape May and Magnolia Warblers also have yellow
rumps, and apparently this ebirder did as well. Suggestion: don't
automatically assume any warbler with a yellow rump is a
"Yellow-rumped". Even though ebird doesn't flag them as rare, they are
much less common than the others right now.
