A dear blogging friend told me about the nickname "Butter Butt" for the yellow-rumped warbler and now I can't refer to them any other way. I passed this knowledge on to my husband and he continually gets it wrong, saying 'butter balls' or 'yellow butts.' I no longer correct him; I know what he means.
