Chimpanzee Fruit Diet: What Percentage Of Calories?

what percentage of calories in chimpanzee diet comes from fruit

Chimpanzees are known to eat a variety of foods, including fruits, leaves, flowers, tree bark, seeds and insects. However, fruit is a key part of their diet, comprising between 60-80% of their food intake. This is because fruit is easy to digest, energy-rich and palatable. Chimpanzees will travel great distances to find fruit, even when it is not abundant. The average daily calorie intake of female chimpanzees is around 2500 Kcal. In this answer, I will explore the percentage of calories in a chimpanzee's diet that comes from fruit.

Female chimpanzees eat more calories when their diets are dominated by ripe fruit

Female chimpanzees eat between 60-80% fruit, which is high in carbohydrates. Fruit is easy to digest, energy-rich and palatable, which is why chimpanzees prioritise it. They will travel great distances to find fruit, and will seek it out even when it is not abundant.

However, when fruit is in short supply, chimpanzees will eat various types of leaves, flowers, tree bark and seeds. They also eat insects, which account for around 4% of their diet.

Protein consumption is also prioritised by female chimpanzees, and protein broadly constitutes 4-33% of their diet. While plant protein is more likely to be available in chimpanzee habitats, animal matter is more protein-dense.

Chimpanzees eat fluctuating amounts of carbohydrates depending on the season and habitat

The amount of carbohydrates eaten by chimpanzees can also depend on the availability of other foods. For example, female chimpanzees eat more calories when their diets are dominated by ripe fruit, but they will also eat lower-quality fall-back foods when preferred foods are abundant. Chimpanzees also eat consistent amounts of protein, with plant protein sources such as young leaves providing considerable amounts. Protein content is positively correlated with food selection in wild chimpanzees, and protein consumption appears to be prioritised.

Chimpanzees eat leaves, flowers, tree bark and seeds when fruit is scarce

Chimpanzees eat a diet of around 2500 calories per day. They eat consistent amounts of protein, with plant protein sources such as young leaves providing considerable amounts, and lesser amounts from fruits and flowers. Animal matter is more protein-dense, but plant protein is more likely to be available in chimpanzee habitats.

Female chimpanzees eat more calories on days when their diets are dominated by ripe fruit, and they eat more fallback foods on days when fruit is less available.

Chimpanzees eat insects such as ants and termites

Chimpanzees use sticks or leaves to prod insect mounds and fish for termites. This was first observed by Dr Jane Goodall in 1960 at Gombe National Park, Tanzania. She saw two chimpanzees using small twigs as tools to fish for termites in the ground, which they then swept into their mouths as a snack.

Chimpanzees also eat honey, which they get directly from bee hives. They eat the bees and larvae which are still embedded in the honeycomb.

Chimpanzees eat honey

Chimpanzees eat a lot of fruit, which generally has a high-carbohydrate content. Fruit comprises between 60–80% of wild chimpanzee diets. However, they also eat other things, such as leaves, flowers, tree bark, seeds, and insects. They consume consistent amounts of protein in low to moderate amounts to meet amino acid requirements. Plant protein sources such as young leaves have considerable amounts, and lesser amounts from fruits and flowers.

Female chimpanzees have been found to ingest more calories on days when their diets are dominated by ripe fruits (whether figs or drupes) than on days when THV (a type of fallback food) dominated their diets. The average daily calorie intake of female chimpanzees is estimated to be around 2500 Kcal.
