The behaviours of a female blonde capuchin (Sapajus flavius) towards her dead infant

Abstract

Abstract Here we describe the behaviour of a female blonde capuchin (Sapajus flavius) towards her dead infant and discuss possible explanations linked to the anecdotal event. We conducted our study in a fragment of Atlantic forest in Northeastern Brazil where we have been monitoring a blonde capuchin population, with over 163 individuals, since 2010. Our observations show that the behaviours of female blonde capuchins towards dead infant include corpse carrying, which may be related to maternal-bond strength and grief management. Two adult males cooperated with the vulnerable female by protecting her during group travelling even though offspring survival was no longer a possibility. The present study complements the current knowledge of thanatology in Neotropical primates.
