title: Mate choice copying versus preference for actively displaying males by female pied flycatchers.
abstract: Should a female copy the mate choice of other females? A female may rank a mated male higher in quality than an unmated male because the former has demonstrated that he is able to attract a female. However, a prospecting female may also avoid a mated male because of the risk that she has to compete with the male's initial mate over access to copulations, breeding resources and male parental care. We studied the mate choice of female pied flycatchers Ficedula hypoleuca, in aviaries divided into three compartments, two for males, and one for a female. A female was allowed to choose (build a nest in a nestbox) between two males after a period when she had been kept in a cage behind a one-way mirror and had presumably seen that one of the males was in the company of another female for 5 h. There was no evidence that females copied the mate choice of conspecific females, or that they avoided males that had recently been in the company of another female. Instead, females apparently chose a mate independently of others, choosing the male showing most courtship display. The latter result explains the consistency in mate choice observed when different females chose between the same pair of males in repeat trials. The ability of females to pick out the same male independently may also explain why a few males obtain most copulations in lekking species.
