In a sinister echo of the passenger pigeon story, chimpanzees in one area of Africa have over-hunted the monkeys they prey on. As a result, the monkey population has been pushed close to local extinction.

If they do switch to a different prey, it's not because they are trying to conserve the red colobus. They're just responding to what they encounter and what they see.. By contrast, humans understand that we can drive a species to extinction.

Humans have made a nasty habit of killing off entire species of animal. Passenger pigeons once formed huge flocks in North America, but humans hunted them on an industrial scale. Largely as a result of this, the species was utterly wiped out by the early 20th century.

This is apparently a time of food shortage in the forest, since the chimpanzees' body weights do decline (Wrangham 1975). This is actually less strongly seasonal than in the Mahale Mountains, where 60% of kills occur in a 2 month period in the early wet season.

At Gombe, red colobus account for more than 80% of the prey items eaten. But Gombe chimpanzees do not select the colobus they will kill randomly; infant and juvenile colobus are caught in greater proportion than their availability (Stanford et al. 1994a, 1998a); 75% of all colobus killed are immature.

When Jane Goodall first observed wild chimpanzees hunting and eating meat nearly 40 years ago, skeptics suggested that their behavior was aberrant and that the amount of meat eaten was trivial. Today, we know that chimpanzees everywhere eat mainly fruit, but are also predators in their forest ecosystems.

One of the main recent findings about hunting by chimpanzees was its seasonality (Stanford et al. 1994a). At Gombe, nearly 40 % of the kills of colobus monkeys occur in the dry season months of August and September.

Chimpanzees over-hunt monkey prey almost to extinction. The apes have killed and eaten so many red colobus monkeys, the population has fallen by 89% and they are having to find new prey.

Although the chimpanzees mostly eat fruit, they also regularly hunt for meat. Their main prey are red colobus monkeys. Between 1995 and 2014, Watts and Mitani observed 556 hunts, 356 of which targeted red colobus. These hunts were very successful: 912 colobus were killed, an average of 3 per hunt.
