Resumo
During observations that took place at the Sítio Monte Mor, Municipality of Limeira, São Paulo, two cases of bigamy among Sicalis flaveola brasiliensis were studied. The females occupied the same territory and built the nests close to one another. No aggression was observed between them, when one would enter each others' nest. The male fed the nestling of both females, even when the brood occurred simultaneously.
