The increased number of young produced by females with high-ranking mates, their higher probability of fledging young, and their increased survival potential appear to increase the reproductive success of these females. Additionally, clutch size and survival of young appear to be more closely associated with the rank of the female's mate than with her own rank. Thus, females mated to low-ranking males may continuously seek opportunities to mate with high-ranking males in order to increase their reproductive success, even if this entails divorcing their current partner.
