Two births of wild proboscis monkeys took place during a 1991/1992 field study at Tanjung Puting National Park, Indonesia. After conception, both females continued copulating with their group’s male. One of the births took place during the night, the other during mid-morning. In the latter case, the infant was born unassisted while the members of the group watched the birthing process. After parturition, the mother consumed the placenta.
