Sexually selected infanticides (SSI) committed by male bears during the mating season has attracted a great research attention, although this type of behavior has been rarely observed in the wild. Here, we document a bear infanticide attempt in the Cantabrian Mountains in which the male killed the adult female during the fight and, subsequently, consumed the carcass for several days. Interestingly, in this case, the bear male tried to reach the cub with the apparent intention of killing it, even though the female was already dead. We complement this observation with data on documented cases of SSI events between 1996 and 2020 in the Cantabrian Mountains. We hypothesize that when females are unintentionally killed while defending their cubs in SSI events, males can benefit by feeding on the carcasses.

尽管在野外很少见到这种行为，但雄性熊在交配季节犯下的性选择杀婴剂（SSI）引起了极大的研究关注。在这里，我们记录了坎塔布连山脉熊杀婴儿的企图，在战斗中，雄性杀死了成年雌性，随后消耗了consumed体数天。有趣的是，在这种情况下，即使雌性熊已经死了，雄性熊仍试图将幼崽杀死，显然是要杀死它。我们用有关坎塔布连山脉1996年至2020年SSI事件记录案例的数据来补充此观察结果。我们假设当雌性在SSI事件中捍卫幼崽时被无意中杀死时，雄性可以通过吃尸体而受益。
