Abstract: Abstract By engaging in extra-pair matings, the most successful males in some bird species can father twice as many young as are present in their own nest1,2. Here we describe a female parallel in goldeneye ducks (Bucephala clangula), whereby some females can double their reproductive output by combining brood parasitism with normal nesting. This huge reproductive advantage should create strong selection for parasitic tactics.
