dc.description.abstract
Thraupidae (Tanagers and allies) show a remarkable array of behaviors, ecologies, morphologies and plumage colors, offering a great opportunity to investigate the evolution of avian mating strategies. We characterize the population genetics and mating system of Sicalis flaveola pelzelni, a socially monogamous Neotropical songbird with biparental care. We found moderate to high levels of neutral genetic variation, similar across three breeding seasons, consistent with large and stable populations, and no temporal genetic structure. Parentage analyses of 114 adults and 198 nestlings (54 nests) revealed 31.8% of extra-pair offspring (EPO) and 51.8% of broods with at least one extra-pair chick. Extra-pair paternity (EPP) rates varied across seasons and were significantly higher in 2014/2015. Neither breeding synchrony nor pair genetic relatedness was significantly associated to EPP rates. Males paired with females in nests with and without EPO were equally heterozygous, and EPO were significantly less heterozygous than within-pair offspring, not supporting the ‘indirect genetic benefits’ hypotheses. Females were more related to their extra-pair mates than to their social mates, not supporting the ‘inbreeding avoidance’ hypothesis. The non-monogamous genetic mating system uncovered here seems not to lower the effective size of the population, which was higher than the sample size of adult breeders. We report and discuss possible cases of quasi-parasitism, as indicated by maternity exclusion patterns. We contribute novel information to expand the knowledge about the largely unexplored genetic mating systems of Thraupidae. Our findings also set the stage for further studies examining if plumage coloration or song traits predict paternity gain or loss in Saffron Finches.
