Evidence of Placentophagia and Mother-Infant Cannibalism in Free-Ranging Macaca mulatta tcheliensis in Mount Taihangshan, Jiyuan, China

Placentophagia or the consumption of the afterbirth is reported in many primate species, whereas cannibalism is a relatively rare event. Based on our field observations over the course of 3 years, we present evidence of placentophagia and mother-infant cannibalism in a free-ranging population of the Taihangshan macaque, Macaca mulatta tcheliensis, in the Mt. Taihangshan area, Jiyuan, Henan, China. We documented 1 case in which a mother consumed the afterbirth of her infant. In a second instance, we observed a fresh placenta discarded on the ground by an unknown individual. We also present a description of the first documented instance of mother-infant cannibalism in the same group of free-ranging rhesus macaques.
