Table 2 depicts lethal interactions with individuals of unknown community membership led by the Rekambo community from January 2017 to June 2019 as a function of date, location, Rekambo party, encountered party, victim(s) and cannibalism. The “date” column contains the specific day of each encounter depicted as “day/month/year”. The “location” column refers to where within the home range of the Rekambo community (January 2017–April 2019) the encounter took place. The location categories are as follows: Core area: within 75% MCP; periphery: 75–95% MCP; out of range: outside 95% MCP. The superscript P indicates that individuals of the Rekambo community patrolled before the encounter. The “Rekambo party” column refers to the number and age-sex classes of the community members seen during the whole encounter. The “encountered party” column refers to the number and age-sex classes of the individuals of unknown communities observed during the encounter. The “victim(s)” column refers to the age-sex class of the individuals of unknown communities that were physically aggressed (e.g., bitten, hit, grabbed) during the encounter. If the attack was lethal, the individual who was killed has the superscript †. The superscripts I and O indicate the kind of evidence available for the event: O = observed event: Observers witnessed how the victim was killed; I = inferred: The individual killed was found dead during the encounter with visual signs (e.g., chimpanzee teeth wounds) of having been killed by chimpanzees. Age-sex classes of individuals in the “Rekambo party”, “encountered party”, and “victim(s)” columns were labeled as follows: number of individuals + age category + sex. A adult, AD adolescent, J juvenile, I infant, F female, M male, U unknown. The “cannibalism” column refers to whether individuals of the Rekambo community fed on the remains of the killed victims
