Hunting of Mammalian Prey by Budongo Forest Chimpanzees

No evidence of short-term exchange of meat for sex among chimpanzees

“…At one extreme, the Ngogo chimpanzees killed and consumed at least 292 prey items during a 34-month study period (~103 prey per year, Watts and Mitani, 2002b). At the other extreme, chimpanzees in the Budongo Forest, Uganda were observed to eat meat only 17 times in more than 10 years (Newton-Fisher et al, 2002;Reynolds, 2005). Even where hunting occurs with some frequency, some individuals rarely if ever gain access to meat (Gombe: Goodall, 1986; Taï National Park, Côte d'Ivoire: Boesch and Boesch-Achermann, 2000;Ngogo: Mitani and Watts, 1999).…”

Cooperation and competition in chimpanzees: Current understanding and future challenges

“…Chimpanzees also hunt other vertebrate prey in habitats where red colobus monkeys do not exist. 43,[91][92][93] Chimpanzees frequently share meat that they obtain in hunts (Fig. 3).…”

<Note> Newly observed predation of wild birds by M-group chimpanzees (Pan troglodytes schweinfurthii) at Mahale, Tanzania

“…A number of predatory habits of wild chimpanzees (Pan troglodytes) have been reported across Africa 1,2,3,4 . Most of these studies have reported mainly meat-eating of mammals.…”

“…When chimpanzees hunt and eat primates of other species, most chimpanzees present actively join in the hunt and the subsequent meat-eating 1,2,12 . In contrast, when preying on non-primate mammals, such as blue duiker, bush pig, and squirrel and so on, chimpanzees hunt in an opportunistic manner and not in groups 3,12,13 .…”
