Animals involved inside the predation had been also described. Relating to the H1 episode (social hunting), independent observers describe and interpret this observation precisely the same way the original observer (MV) did. This occasion was videotaped, so it will be feasible to test observer reliability by getting three na?ve observers (unaware of the original description and interpretation).3. ResultsBetween 2007 and 2011, five occurrences of predatory behavior by the FM chimpanzees had been straight recorded (Table two). Each and every of the predatory events happened during the each day routine activities on the group and all the situations beneath are described in chronological order. Within the initially episode, the complete group was involved within the predation (social hunting), when in the other episodes the predation incident was Ing the biological relevance of captive environments. Appl. Anim. Behav. Sci. performed individually. Even though some other predation incidents occurred for the duration of this five-year period, we only registered these in which one of the researchers was present in the beginning for the end in the episode (observed kills). Through the study period we discovered some post-kill proof (n = ten species) but we discarded it for the reason that we didn't have specific information regarding how it was developed. The post-kill evidence refers mostly to the following species: Passer domesticus, Apodemus sylvaticus, Natrix natrix, Hyla meridionalis, Rana perezi, and Bufo bufo (Table three).three.1. Case 1 (H1)��19 January 2007. Social Predation of a Rabbit (Oryctolagus cuniculus)This episode was title= journal.pone.0123503 recorded on 19 January 2007. It began at 17:10. Four chimpanzees took an active portion within the predation: two juvenile females, one young male and one juvenile male (Figure 1). A rabbit (Oryctolagus cuniculus) came in to the enclosure by possibility. It was finally captured by the four chimpanzees following two attempts in which the hunters took on unique roles inside the action. The initial try was created by 3 chimpanzees (a single juvenile male and two juvenile females). The male (Bongo) pursued the prey when the females (Sara and Waty) positioned themselves for an ambush to block the rabbit��s escape route and to capture the animal (Figure 1). The second attempt was performed by all 4 chimpanzees (a single young male, one particular juvenile male and two juvenile females). Among them (Juanito) performed the part of pursuer even though the others (Waty, Sara and Bongo) setup an ambush in a semicircular position, blocking and capturing the prey. Once the hunting episode was completed, the other 3 chimpanzees joined the group: one adult female (Romie), one particular title= title= fnint.2013.00038 target='resource_window'>1745-6215-14-222 adult male (Toto) and a single young male (Nico). Each of the individuals gathered about the rabbit, which was taken by its hind legs by the oldest chimpanzee (Toto) and beaten after against the ground with a single fatal blow. Quickly, a sequence of exploration and brutal play behaviors started among the five juvenile and young individuals (Figure 2). The prey was not consumed, while some people attempted to bite it.3.two.
