Using statistical models that controlled for the effects of male coloration, and the effects of age and condition of both parents, we found that carotenoid‐based female coloration was positively linked to key proxies of bird lifetime reproductive success: clutch size, fledgling success and recruitment.

Finally, UV‐blue female coloration was positively linked to female survival and marginally linked to laying date. Taken together, these results show for the first time in a natural population that female coloration can indicate individual and maternal quality under natural and adverse reproductive conditions. They highlight the potential for the evolution of female ornamental traits through sexual selection.</jats:p> Female coloration indicates female reproductive capacity in blue tits Journal of Evolutionary Biology |
