Can capuchins receive adequate primary diet from an enrichment unit? (2003)

Webster, S. J. G.

Abstract

The capuchins need to align the holes in the rotating disk with the cavities containing the food in order to be fed. ..There are fewer leftover pieces of the primary diet when the diet is consumed through use of the foraging unit. .. The capuchins receive slightly over 81.6% of their primary diet from this unit.
