Primatology has many applications relating to species conservation, population growth efforts, and understanding evolution. Non-human Primates in captivity deserve the best care available; understanding social development at a young age is critical in providing this. Western Lowland Gorillas were observed from the fall of 2022 through the summer of 2023 at Franklin Park Zoo. This group included 5 related individuals and one unrelated silverback male. The two youngest individuals, Aziza, age 7, and Pablo, age 3, were the focus of this research. Timed 1-minute internals were used for focal observations approximately 3 times a week. Out of 22 behaviors, Pablo’s highest active behavior was social play, at 7.52%. Eighty-six percent of this behavior was with his sister Aziza, with 24% spread among the other gorillas. Aziza was beginning to engage in more adult behaviors over the observation period, with increased time spent self-grooming. Overall, these two individuals showed typical age-appropriate behaviors for young gorillas, in a socially well adapted group. This shows the importance of maintaining a family-like group for gorillas to provide opportunities for species-specific social development in captivity.
