Optimal foraging in the captive-bred common marmoset, Callithrix jacchus (1994)

Morrissey, G.

Abstract

The dominant pair, when given the choice, preferred to forage from the high-level box [filled with deep litter containing raisins], allowing the other group members to forage mainly at ground level. .. When feeding at floor level the marmosets took a raisin and retreated to the branches to each it. .. By foraging at high level they will, unlike the other [low ranking] group members, avoid predation.
