AbstractDespite the advantages of lasting pair bonds and prevalence monogamy, at least in avian species, some individuals switch mates (divorce). Divorce is generally considered to be adaptive (i.e., conferring net fitness benefits), although its causes consequences often remain unclear, most notably regarding genetic basis this behavior. Using more than 30 years data a long-lived bird with obligate biparental care, Alpine swift, we first described overall patterns mate nest site fidelity investigated predictors between-year divorce. We show that 16.6% pairings ended divorce, low reproductive success young age as males retained females. By then studying individual repeatability heritability moderate females little additive variance either sex. Finally, assessed divorce report an active decision modify bond (divorce) may beneficial reactionary re-pairing following partner's death. Overall, provide benefits for swifts, but no microevolutionary potential behavior evident population.
