OK so I'm a British birder not a local but I'm with Toe. If the feathers are a problem look at the bird's structure. A) structurally this looks too delicate for a Yellow Rumped to me -especially the bill which looks sharper. B) The yellow wash on the breast is far more like a Cape May. Yellow rumps tend to have yellow on the flanks don't they? But I might be wrong.
