Abstract:
I report the first documented case of a wild siamang killed by a clouded leopard. The event, involving a juvenile male (weighing 3.7 kg), occurred at dawn, near a known sleeping tree in a lowland tropical forest in southern Sumatra (Indonesia). Examination of the siamang's body revealed that the first 2 cervical vertebrae were crushed and the face was partially eaten. This attack highlights the potential importance of predation as an evolutionary pressure for hylobatids, and poses some questions about the antipredator adaptations of this population of siamang.
