Final answer:
Red colobus monkeys likely avoid predation by chimpanzees through display behavior and an understanding of primate social dynamics and hunting strategies helps in this context.
Step-by-step explanation:
Red colobus monkeys are more likely to avoid predation by chimpanzees when they exhibit certain behaviors that are typical for primates in deterring threats. Although the specific strategy that red colobus monkeys use was not provided, we can infer from knowledge that primates often use display behavior to ward off predators and rivals without the need for physical confrontation. This non-violent approach can include visual signals, body movements, and vocalizations to communicate dominance or territorial boundaries. In addition, understanding the social dynamics and hunting strategies within and between different primate species can be insightful. For example, the chimpanzees in Gombe National Park hunt red colobus monkeys with their hands, and differences in behavior are observed between chimpanzees in different environments.
