Here, we present the first record of polyandrous reproductive behavior in Boa constrictor within the Brazilian Cerrado. On 29 June 2024, at 11:00 h, three adult individuals (two males and one female) were observed engaging in mating behavior in a rural area of the municipality of Pereira Barreto, state of São Paulo. Sex was identified based on tail morphology. Both males copulated alternately with the same female, with no evidence of agonistic interactions. The event lasted approximately 30 minutes and occurred during the dry season, coinciding with the species’ reproductive period. Boa constrictor is viviparous, exhibits size‑dependent sexual maturity, and shows high ecological plasticity. This record expands current knowledge of the species’ reproductive biology in the Brazilian Cerrado.Referencias
