Abstract
We investigated the causes and consequences of crop-raiding for the ecology and life-history of two troops of olive baboons studied in Nigeria’s Gashaka Gumti National Park over 8 years. Kwano troop feeds entirely on wild foods whilst the Gamgam troop regularly consumes crops grown within its home-range. Crop-raiding provides both energetic and reproductive advantages as Gamgam troop spent less time travelling and feeding and more time resting and socialising. The crop-raiding troop has also shorter inter-birth intervals and lower infant mortality. Costs to crop-raiding due to chasing and attacks by farmers are outweighed by the benefits of increased access to high-quality foods, a reduced susceptibility to pathogen loads, and a consequently increased reproductive output.
