Primates: Feed individuals in social groups
A before-and-after study in 1998 in Italy (Visalberghi et al. 1998) found that capuchins Cebus apella ate more unfamiliar foods when they first encountered them if they were in the presence of their groupmates than if they encountered them when alone. The average number of food samples the capuchins ate averaged six as individuals, but 15 in a social condition. After the first encounter, consumption of the unfamiliar foods became equivalent to when they encountered the food alone. Capuchins were presented with eight novel food types in one of two conditions: individual and social. Each animal received four food types individually and another four with groupmates. (CJ)
