There is variety in warbler song, then there is Sherburne's Cerulean. Not sure who he learned to sing from, but it was not a close relative.
Some days I'm certain that it is the Cerulean singing, other days I scratch my head as he throws in portions of other warblers. Today is the latter. And then there's always the "h" word, although he appears Cerulean enough. Sigh.
