International audience Interspecific brood parasitism (IBP) involves individuals of one species leaving the incubation and rearing of their brood to another species, while conspecific brood parasitism (CBP) involves a female laying its eggs in the nest of another of the same species (Robert & Sorci 2001; Lyon & Eadie 2008). CBP is a common reproductive tactic in Anatidae, found in 46% of species including the Common Eider Somateria mollissima (Yom-Tov 2001), while IBP is infrequent in precocial species such as Anatidae (Robertson 1998).
