Infanticide, although common in a wide range of species including humans and other primates, is poorly understood. A 7-year study under natural conditions reveals that infanticide within colonies of black-tailed prairie dogs (Cynomys ludovicianus) is striking for three reasons. It is the major source of juvenile mortality, accounting for the total or partial demise of 51 percent of all litters born. The most common killers are resident lactating females. The most common victims are the offspring of close kin.
杀婴行为虽然在包括人类和其他灵长类动物在内的广泛物种中都很常见，但人们对此知之甚少。一项为期 7 年的自然条件下的研究表明，黑尾草原犬鼠（Cynomys ludovicianus）群体中的杀婴行为有三个显著特点。它是幼崽死亡率的主要来源，导致所有出生幼崽的总数或部分死亡，比例达到 51%。最常见的凶手是居住的哺乳期雌性。最常见的受害者是近亲的后代。
