Mate selection based on genetic relatedness and sexual ornamentation across the breeding season. (a) No difference in pairwise relatedness between potential partners at the time of pairing and chosen social partners early in the breeding season. Chosen extrapair males are less related to female than available males or chosen social males. Late in the breeding season, more genetically dissimilar social and extrapair mates were selected compared to all available mates. (b) Elaboration of sexual ornamentation in males available for pairing and males selected as social and extrapair mates early and late in the breeding season. Numbers above the bars indicate the sample sizes and solid lines connect groups that did not differ statistically. (c) Comparison of relatedness of individual females to their social and extrapair mates. Points below the dashed line of equal relatedness indicate that the female's extrapair male is less related to female than the female's social male.
