Low sociality (1% of grooming time: territorial overlapping by males to female ranges, solitary 90% of the time, unless large feeding source, little grooming, orangutans. Females 5 year inter birth intervals (ibi: adult male bi-maturism and force copulation, male long call. Since the killer is outcompeting the male the female is currently with she is more attracted to the killer. Fission-fusion: community size = 20-150, range = 5 km a day, 80% of food in trees, aggressive yet affiliative, border patrols, high ranking females stay, but most transfer. 2: may venture into neighbouring communities, females may go days without seeing a male, we call it fission-fusion because individuals recognize who is in their social group.
