Este estudo apresenta o primeiro registro de comportamento reprodutivo poliândrico em Boa constrictor no Cerrado brasileiro. Em 29 de junho de 2024, às 11h, três indivíduos adultos (dois machos e uma fêmea) foram observados em comportamento de acasalamento em uma área rural do município de Pereira Barreto, estado de São Paulo. A identificação sexual baseou‑se na morfologia da cauda. Ambos os machos copularam alternadamente com a mesma fêmea, sem evidências de interações agonísticas. O evento teve duração aproximada de 30 minutos e ocorreu durante a estação seca, coincidindo com o período reprodutivo da espécie. Boa constrictor é vivípara, apresenta maturidade sexual dependente do tamanho corporal e elevada plasticidade ecológica. Este registro amplia o conhecimento sobre a biologia reprodutiva da espécie no Cerrado brasileiro.Referências
