swelling is an important factor in the sexual life of Moor macaques. As this species does not have a marked reproductive season, not all females swell at the same time. Females start to swell between the age of 4 years and 6 years and have their first child between the age of 6 years and 7 years. Swelling individuals are more likely mounted by the males than non-swelling ones. The dominant and oldest female of the group is usually mounted by the alpha male. Non-alpha males only mount females when the alpha is out of sight and lower ranking males usually mount non-swelling females, although in most Moor macaque groups, there is only one male. Poor dietary factors appear to be associated with a delay in the onset of perineal swelling and first parturition. From the end of the rainy season to the start of the dry season, there appeared to be a rise in births. The moor macaques are classified as moderately seasonal breeders based on the fact that 33-67% of their newborns occur in a single three-month period. The peak might be explained by yearly increases in food supply, particularly a rise in fruit. Female reproductive state differences within a group may have an effect on female furcation patterns, which may be more noticeable in egalitarian species where social interactions are less impacted by dominance or kinship. This furcation pattern may be caused by the tendency of adult females that are not cycling to stay near to one another. Social behavior Changes in group fission process and furcation patterns may reflect differences in social characteristics among species as well as ecological and demographic differences among populations; thus, studies of group fission may contribute to our general understanding of why primates live in a variety of groupings. Special relationships between certain males and females can either trigger or encourage group fission. In Moor macaques, however, significant connection between specific males and females does not appear to affect the process of fission. Moor macaque females are not actively involved in intergroup interactions. On the other hand, male aggression toward other groups is significantly more frequent than female aggression. Adult female furcation patterns can be anticipated by their connection with one another, such as grooming behavior, prior to group fission. However, the grooming habit of mature female Moor macaques was unrelated to the furcation. Individuals of similar age, sex, or rank
