Canvasback

“Doctor, doctor, my wife thinks she’s a duck.”

“You better bring her in to see me straight away.”

“I can’t do that – she’s already flown south for the winter.”  

Interesting Fact: The species name of the Canvasback, Aythya valisineria, comes from Vallisneria americana, or wild celery, whose winter buds and rhizomes are its preferred food during the nonbreeding period.  ( https://www.allaboutbirds.org/guide/Canvasback/lifehistory )
