Monkeys are fascinating creatures that share many similarities with humans. One thing we have in common with monkeys is a love for sweet, yellow bananas! But have you ever wondered just how many of these popular fruits our primate pals eat on a daily basis?
If you’re looking for a quick answer, research shows that on average, monkeys tend to eat around 10-15 medium-sized bananas per day.
In this comprehensive guide, we’ll explore the banana-eating habits of monkeys in more detail. We’ll look at factors like monkey species, age, size, activity level, and more to understand the large spectrum of possible daily banana consumption.
Key Factors That Influence Monkey Banana Consumption
Species
Different monkey species have varied appetites and preferences for bananas. For example, spider monkeys tend to be more fruit-loving and may eat up to 2.2 lbs of bananas per day on average. In contrast, Howler monkeys prefer leaves and darker ripe fruits as staples so may only snack on the occasional banana.
Age
Baby monkeys and juveniles tend to eat more frequent small meals of banana and other fruits to fuel growth and activity. An infant capuchin may eat over 1 lb of bananas a day. As monkeys mature, their metabolism slows and fruit intake often decreases as well.
Size and Weight
Larger monkey species like mandrills naturally require more daily calories. An adult male mandrill can weigh over 70 lbs and eat 70-80 bananas per day – far more than a 5 lb pygmy marmoset that sticks to a couple bites from 1 banana at most.
Activity Level
The more active the monkey, the more fuel its body needs. Troops of patas monkeys foraging over several miles daily rely on bananas and other fruits for quick energy. Less active monkeys like lorises and tarsiers have lower fruit intake needs.
Climate and Geography
In some habitats, seasonal changes can influence banana availability which affects consumption. Monkeys in Central America may eat less bananas during dry months when fewer banana trees fruit. However, those living near Ecuadorian cloud forests enjoy peak banana eating opportunities year-round.
Captivity vs. Wild
| Captivity | Wild |
| More stable banana supply | Deals with scarcity during certain seasons |
| Fewer calories needed to forage over large territories so banana intake may be less | Burns more calories ranging forests so often eats more bananas when available for energy |
| On average captive monkey eats 0.5 – 1.5 lbs bananas/day depending on size | On average wild monkey eats up to 2.2 lbs bananas/day depending on species and food availability |
As the comparisons show, a monkey’s environment and activity levels directly impact how many bananas it can eat per day. Be sure to also check out more monkey fruit diet insights at sites like National Geographic.
Average Banana Consumption by Monkey Species
Capuchins
Capuchin monkeys are New World monkeys that inhabit Central and South America. These intelligent primates have a varied diet consisting of fruits, nuts, seeds, flowers, insects, frogs, lizards, bird eggs and small mammals. Bananas make up a significant portion of their frugivorous diet.
Research shows that capuchins consume on average around 10-15 medium-sized bananas per day.
Spider Monkeys
Spider monkeys are large, long-limbed New World primates found in tropical forests. They get their name from their spider-like movement as they brachiate through the trees. Spider monkeys are primarily frugivores, with ripe fruits comprising up to 80% of their diet.
Studies estimate that spider monkeys eat around 7-12 bananas daily on average. Their long tails allow them to easily hang and reach for banana bunches.
Mandrills
Mandrills are colorful Old World monkeys native to the tropical rainforests of west central Africa. They are closely related to baboons. Mandrills are omnivores and consume a wide variety of foods including fruits, seeds, leaves, bark, roots, insects, small vertebrates and even smaller monkeys.
Bananas are one of their favorite foods. Researchers observing mandrills in Gabon found they can eat around 30 bananas each day.
Macaques
Macaques constitute the most widespread non-human primate genus globally. They inhabit regions of Africa, Asia and Europe. Macaques are opportunistic omnivores but fruit comprises 50-60% of their diet. Studies on Japanese macaques show they consume 4-6 bananas daily on average.
Some macaque species raid farms and human settlements for bananas, leading to human-wildlife conflict.
Chimpanzees
Chimpanzees are apes native to sub-Saharan Africa. They are Earth’s closest living relatives to humans, sharing 98% of our DNA. Chimps are omnivorous and opportunistic foragers. Wild chimps spend most of their day finding and eating fruits, with figs being a favorite.
Researchers following chimps in Uganda recorded them eating around 2-3 bananas each day on top of other fruits. Bananas are relished by captive chimps too.
Marmosets
Marmosets are diminutive New World monkeys native to South America. Despite their small size, they have a huge appetite for fruit. Up to 90% of their diet consists of tree sap, nectar and fruits like bananas. Field studies reveal that each marmoset consumes around 5-8 small bananas per day on average.
That amounts to quite a lot relative to their body size – the equivalent of a human eating more than a 100 bananas daily!
Calorie Requirements Based on Weight and Age
The number of calories a monkey needs per day depends largely on their weight and age. Here’s a breakdown of the estimated daily calorie requirements for monkeys:
Infant Monkeys
Infant monkeys that are still nursing likely consume around 50-60 calories per 100g of body weight. This translates to:
- A 1 kg infant monkey needs 500-600 calories per day
- A 2 kg infant monkey needs 1,000-1,200 calories per day
These calories are met entirely through breastmilk while the infants are still nursing. As they begin to sample solid foods, their caloric intake will increase.
Juvenile Monkeys
Juvenile monkeys that have been weaned likely need 35-50 calories per 100g of body weight. For example:
- A 3 kg juvenile monkey needs 1,050-1,500 calories per day
- A 5 kg juvenile monkey needs 1,750-2,500 calories per day
These estimated calorie needs account for their increased activity levels and growth rates.
Adult Monkeys
The calorie requirements for adult monkeys vary more significantly based on their size, species, and activity levels. As a general guideline:
- Small monkey species (under 5 kg) need around 50-70 calories per 100g of body weight per day
- Medium monkey species (5-15 kg) need around 45-65 calories per 100g of body weight per day
- Large monkey species (over 15 kg) need around 35-55 calories per 100g of body weight per day
For example, an adult 10 kg patas monkey would need around 4,500-6,500 calories daily. These estimates account for maintaining healthy body condition while engaging in their natural active behaviors.
In captivity, calorie needs may shift depending on activity levels and diets, so intake should be adjusted accordingly based on weight trends over time.
Digestion Rates and Feeding Habits
Digestion Time
How long does it take for monkeys to digest their food? The answer depends on a few factors. Monkeys are omnivores and eat a varied diet including fruits, vegetables, seeds, eggs, and small animals. Their gastrointestinal tract is designed to digest both plant and animal matter.
On average, it takes 12-20 hours for most monkey species to fully digest a meal. This allows time for the food to be properly broken down by enzymes and absorbed by the intestinal tract before waste is eliminated.
Smaller monkeys like marmosets digest their food very quickly, in just 4-6 hours. Their high metabolism requires them to eat frequently throughout the day. Larger primates like gorillas can take up to 30-50 hours to fully digest their food as it moves slowly through their lengthy intestinal tract.
This adaption allows them to extract as many nutrients as possible from the large amount of fibrous vegetation they consume.
The type of food monkeys eat also impacts digestion time. Easily digestible foods like ripe fruit may pass through the gut within a few hours. However, high-fiber vegetation and vegetation with toxins require longer processing. Foods higher in fat or protein also take more time to break down.
Overall, the digestive system of monkeys is quite efficient at extracting nutrients from the variety of foods in their diet.
Meal Frequency
Wild monkeys tend to eat small, frequent meals throughout the day rather than gorging at one time. Most species eat between 3-5 times per day. Meal frequency depends on factors like habitat, food availability, and social structure.
Arboreal primates like squirrel monkeys often eat almost constantly while foraging in trees. This steady nourishment provides energy for their active lifestyle. Terrestrial monkeys like baboons may have more intermittent meals dependent on what food sources they find while traveling on the ground.
Nocturnal primates like owl monkeys tend to eat more at night when they are awake and active.
The social structure of monkeys also impacts how often they eat. Species that travel in large troops make frequent pit stops to eat. Solitary primates or pairs tend to eat only when they find a good source of food.
During seasons when preferred foods are abundantly available, monkeys may eat almost continuously.
In zoos and wildlife parks where food is provided on a schedule, most monkeys receive 1-3 feedings per day. This is spaced to allow full digestion between meals. Proper nutrition is important to maintaining healthy digestive function.
Preferred Parts of Banana
Bananas are one of the most popular fruits provided to monkeys in captivity. Both chimpanzees and monkeys relish the sweet taste of ripened bananas. In the wild, bananas comprise only a small part of their diverse diets.
When eating a banana, primates prefer the fleshy pulp and soft inner portion. The digestible sugars and carbohydrates in the pulp provide quick energy. The flesh is easy for their stomachs to break down and absorb.
Monkeys also enjoy the taste and texture of the inner banana versus the more fibrous peel.
Chimpanzees and monkeys do sometimes eat small pieces of banana peel, as the peels contain beneficial prebiotics and polyphenols. However the peel is harder to digest and lacks the appealing flavor. Given a choice, primates will almost always opt to peel the banana first before eating the soft, sweet contents inside.
Role of Bananas in Captive vs. Wild Monkey Diets
Bananas are a staple food source for many captive monkeys, providing an excellent source of energy, nutrients, and variety in their diet. However, wild monkeys eat a much more diverse diet consisting mainly of leaves, flowers, fruits, seeds, stems, and sometimes insects and small animals.
In captivity, monkeys are typically fed a specially formulated commercial primate diet to provide complete nutrition. This dry food is often supplemented with fresh fruits and vegetables like bananas, apples, oranges, lettuce, carrots, and sweet potatoes.
Bananas in particular are a favorite treat due their sweet taste, soft texture, and convenience.
According to nutritionists at major zoos and research facilities, bananas should only make up about 10% of a captive monkey’s diet. An over-reliance on bananas can lead to obesity and nutritional deficiencies in monkeys if not balanced with other foods.
Some facilities aim for monkeys to consume 70-90% dry commercial diet, with the rest coming from fresh produce like bananas.
In contrast, wild monkeys have a diverse diet determined by seasonal availability. African monkeys like vervets and baboons feed on fruits, seeds, pods, leaves, vines, and flowers. Rainforests support many banana and plantain trees, but wild monkeys consume these sporadically as they ripen.
Bananas contain lots of energy but fewer nutrients than leaves and flowers.
According to research on wild monkey diets in Costa Rica and Uganda, bananas and cultivated fruits make up no more than 15% of their total diet. The rest comes from natural vegetation. Wild monkeys also eat different parts of the banana plant like the pseudestem, male buds, and banana flowers which provide fiber and nutrients.

Conclusion
As we’ve explored, how many bananas a monkey eats per day can vary greatly depending on species, size, age, activity level, and habitat. An active adult spider monkey might eat up to 15 medium bananas daily, while a tiny marmoset may only eat a quarter of a small banana.
However, most monkeys tend to consume 10-12 average-sized bananas per day on average. This fruit makes up an important part of both wild and captive primate diets thanks to its soft texture, digestibility, and abundance of key nutrients like potassium, fiber, vitamin B6, vitamin C, and more.
Understanding the role of bananas and the factors that influence consumption gives us fascinating insight into monkeys and their fruit-loving lives. Next time you see a monkey eagerly peeling a banana, you’ll have a deeper grasp of their eating habits behind the scenes!
