Host–parasite kinship in a female‐philopatric bird population: evidence from relatedness trend analysis
Abstract Conspecific brood parasitism (CBP), an alternative reproductive tactic where some females lay eggs in the nests of other females of the same species, occurs in many animals with egg care. It is particularly common in waterfowl, for reasons that are debated. Many waterfowl females nest near...

Absence of a population trend in female pairwise relatedness vs. distance implies that host–parasite relatedness is not only an effect of strong natal philopatry: some additional form of kin bias is also involved.
