Aythya americana Redhead Rotkopfente The Redhead is known to leave eggs in the nests of canvasbacks. This is probably a survival mechanism. It is safer to let another female incubate one or more of your eggs, in case a predator finds your nest. In other words, do not place all your eggs in one basket. Portage County, Wisconsin, USA |
