Socially monogamous birds may break up their partnership by a so-called ‘divorce’ behaviour. Divorce rates vary immensely across avian taxa that have predominantly social mating system. Although various factors associated with divorce been tested, broad-scale drivers of rate remain contentious. Moreover, the influence sexual roles in still needs further investigation because conflicting interests males and females over fertilization. Here, we applied phylogenetic comparative methods to analyse one largest datasets ever compiled included from published studies 186 species 25 orders 61 families. We tested correlations between group factors: ‘promiscuity’ both sexes (propensity polygamy), migration distance adult mortality. Our results showed only male promiscuity, but not female had positive relationship rate. Furthermore, was positively correlated rate, whereas mortality no direct These findings indicated might be simple adaptive (by selection) or non-adaptive strategy accidental loss partner) it could mixed response conflict stress ambient environment.
