One or two Canvasback ducks usually show up in Maine during each fall or winter.  But last year during my Maine Big Year I scoured all the likely locations hoping to find one . . . but to no avail.

Then yesterday, there were eight Canvasbacks on Cobbosseecontee Lake in Monmouth, Maine. This is a bird that breeds in western Canada, and migrates to the American south and California for the winter.   These birds are a quite a bit further east than normal . . . and thus a real thrill for Maine Birders.

The Canvasbacks were joined by a bunch of other diving ducks that moved back and forth in front of us as we watched them from the Cobbosseecontee causeway.
