ABSTRACT
Predatory behavior in wild chimpanzees and other primates has been well documented over the last 30 years. However, as it is an opportunistic behavior, conditions which may promote such behavior are left up to chance. Until now, predatory behavior among captive chimpanzees has been poorly documented. In this paper, we present five instances providing evidence of predatory behavior: four performed by isolated individuals and one carried out in cooperation. The evidence of group predation involved the chimpanzees adopting different roles as pursuers and ambushers. Prey was partially eaten in some cases, but not in the social episode. This study confirms that naturalistic environments allow chimpanzees to enhance species-typical behavioral patterns.

animals-02-00363-f004: Predation of a Larus michahellis (Episode H3) by Male Group.

Mentions: The episode was recorded on 2 August 2008 between 17:22 and 17:38. Three individuals were involved in the hunting episode. An adult Larus michahellis specimen remained in the artificial pool of the enclosure. Charly (Group A, adult male) captured the prey with his hands. We neither recorded the killing strategy nor who was the actual killer. Immediately afterwards Marco (Alpha male) took hold of the already dead prey and carried it to one of the enclosure towers accompanied by Bongo (adolescent male) and by Charly (Figure 4(a)). Charly left the tower after one minute. Bongo and Marco remained together until the end of the episode. From 17:25 to 17:27, Marco examined the prey. During this time, Bongo simply observed without taking part. At 17:28, Bongo struck the head of the prey with his hands. At 17:29 Marco began ripping off one of the lower limbs of the prey (Figure 4(b)). At 17:32 he bit the limb of the prey to pull it apart (Figure 4(c)). Marco ended up abandoning the prey in the tower structure.
