99 sib ibl Weour ‘facultative ’ model we suggest that siblicide is far less common than previously supposed, and that it occurs only when resources are insufficient to sustain two cubs. According to this facultative model, intense neonatal aggression functions to establish intralitter dominance rather than to kill siblings. Furthermore, differences in litter size and composition between captive and field settings previously used to support the obligate model are assumed in the facultative model to be due to prenatal factors rather than to postnatal siblicide. Here we tested the predictions of these two hypotheses with 10 years of field data from hyaenas inhabiting the Masai Mara National Reserve, Kenya. We found that, although sex compositi...
