摘要红嘴鱼(Crotophaga Ani)是一种兼具合作与繁殖竞争的多元繁育、共生筑巢物种。我们报告了在公共离合器完成后加入群体的成年人杀害幼鸟的间接证据。我们提供的证据表明，在杀害婴儿后捕获的一些成群幼鸟与任何幼鸟都没有关系，可能是为了增加重新捕获的机会。
Abstract The Smooth-billed Ani (Crotophaga ani) is a plural-breeding, joint-nesting species that engages in both cooperation and reproductive competition. We report circumstantial evidence for infanticide of chicks by adults that joined a group after completion of the communal clutch. We provide evidence that some of the group adults captured after the infanticide were unrelated to any of the chicks and may have acted to increase chances of renesting.
