Chimpanzees regularly hunt for meat in the wild, including both solo and group hunting; however, theft of prey from non-chimpanzee hunters, or scavenging of carcasses is extremely rare. Here we report the first observations of a novel prey capture technique by the chimpanzees in two adjacent communities in the Budongo Conservation Field Station, Uganda. In both cases blue duikers were found caught in human laid snare traps, and then retrieved by the chimpanzees. In one case the duiker was still alive when retrieved and subsequently fully consumed by the chimpanzees. In the other, the chimpanzees encountered the duiker while alive, but retrieved it soon after its death; here only a small portion was consumed. These observations are discussed in comparison to observations of chimpanzee hunting, scavenging, and their exploitation of an environment increasingly modified by human activity.

Video S2. Duiker is retrieved by female chimpanzee Kipepeo. Hearing that the chimpanzees had remained in the area, after freeing the duiker the observers hid themselves from view in nearby foliage and continued to film. Female chimpanzee Kipepeo can be seen returning to the site (face visible at 8 s) and reaching her hand out (11 s) to retrieve the carcass (13 s). (MOV 5,288 kb)
