From: Certainty of paternity in two coucal species with divergent sex roles: the devil takes the hindmost

Fig. 4

Sex ratios (± 95% credible intervals) of completely genotyped clutches with (black circles) and without extra-pair paternity (open circles) and among all extra-pair and within-pair offspring in (a) black coucals and (b) white-browed coucals. In both coucal species the sex ratios of clutches with and without extra-pair young, and the sex ratios of extra-pair and within-pair offspring did not differ from parity. The stippled horizontal line represents a balanced sex ratio (parity). The low incidence of extra-pair paternity in white-browed coucals results in large error bars for sex ratios of clutches with extra-pair paternity and extra-pair offspring in this species. The numbers above the error bars represents the number of clutches or offspring, respectively. For the interpretation of statistical differences using posterior means and 95% credible intervals see Fig. 1 and methods
