Seasonal diet changes of the forest hog (Hylochoerus meinertzhageni Thomas) based on the carbon isotopic composition of hair

The stable carbon and nitrogen isotope composition of forest hog hair is used to estimate seasonal diet changes in forest hogs from Queen Elizabeth National Park, Uganda. This detailed record of diet shows that the forest hogs on Mweya Peninsula consume up to 20% grass at the beginning of the rainy season, and very little grass during the rest of the year. Correlation of isotope patterns between individuals from the same sounder show that a single animal records the group behaviour.
