Ontogenetic Changes in Feeding Behaviors in Tufted Capuchins.

ABSTRACT: Wild juvenile capuchins exhibit lower feeding success than adults, particularly for mechanically challenging foods, but ontogenetic changes in oral food processing behaviors related to this reduced success are unknown. We test how oral food processing efficiency varies across development in an experimental setting in tufted capuchins (Sapajus spp.). Further, we simulate discontinuous feeding observations to test the comparability of behaviors measured in wild and captive settings. Twenty-nine captive and semi-wild infants (n = 2), juveniles (n = 12), older juveniles (n = 4), and subadults-adults (n = 11) were video recorded while feeding at the Núcleo de Procriação de Macacos-Prego Research Center (Araçatuba, Brazil). Each animal was offered a series of five foods ranging in volume, toughn
