Until now, there was apparently little difference in diet between male and female chimps, leading to an assumption that the role of man as hunter and woman as gatherer in humans occurred following the split from the last common ancestor of humans and chimpanzees about 5 million years ago, Fahy said.
I am reading different numbers. On average, nine days a year are meat days for chimps. Bonobos appear to eat even less meat than chimps. A recent study of the carbon and nitrogen isotopes in bonobos placed bonobos at a trophic level slightly lower than one antelope species. The Pterygota mildbraedii is a large tree common throughout the Ngogo chimpanzee habitat, and it is among the primate's key food sources. Data regarding the chimpanzees and two species of saplings, Pterygota mildbraedii and Celtis africana, were collected from Ngogo in Uganda's Kibale National Park.
The Ngogo chimpanzee community is the largest observed in the world - more than animals - and has been actively studied since Daily feeding observations from , made primarily during the dry season months of June through August, of 41 adult male chimpanzees were analyzed for eating patterns. These were compared to nutrition samples from Pterygota mildbraedii and Celtis africana. Leaf samples were taken from different saplings and at various feeding times during the day.
Pterygota mildbraedii is a very large tree, common throughout the Ngogo chimpanzee habitat. The chimpanzees, however, eat young leaves of the saplings found near the forest floor. This study found that the leaves' hemicellulose - a more digestible fiber - and nonstructural carbohydrates - simple sugars and starch - increased 15 percent to percent, respectively, from morning to evening.
Cellulose and lignin, which make the leaves more difficult to digest, also decreased by day's end. Celtis africana is a smaller tree than Pterygota , the saplings of which contain many thin branches and small leaves. Milk At Tchimpounga Sanctuary, infant chimpanzees are fed specially formulated milk until they are ready to eat solid food. Infant chimpanzees nurse for at least five years and stay with their mothers even longer, learning to care for their younger siblings.
Orphaned chimpanzees are often malnourished and in urgent need of nutrition and care. The Team Our Board. Annual Reports. All cool stuff Media Inquiries.
Get in Touch Book a Presentation. From the field. Everything tastes good! Chimpanzees eat a wide variety of food. Scientists have recorded about 80 different items chimps eat, including seeds, fruit, leaves, bark, honey, flowers, and insects. This makes up most of their diet. However, chimpanzees also hunt other wildlife, like monkeys or small antelope, for meat. Feeding is usually an individual activity, but sometimes chimps look for food together.
Clever primates. Chimpanzees are famous for using tools to get food. They often strip a branch of its leaves and then dip it in an ant or termite hill to get the insects inside. When water is scarce, chimps chew leaves so they are soft and sponge-like—this allows them to then soak up rainwater inside of tree holes. All in the family. Home for a chimpanzee is a community of other chimps made up of family groups. Within these family groups there are usually about 6 to 10 individuals.
