Marmoset monkeys are small and charming creatures that a lot of people love. 

They’re a type of New World monkey from Central and South America. 

These little monkeys eat both plants and animals, so they’re called omnivores. 

In the wild, they munch on fruits, insects, and small animals. 

But when they’re kept in captivity, they can eat different kinds of foods, like special diets made just for them or even some human foods. 

In this exploration, we’ll discuss what they eat at different stages of their lives, from when they’re babies to when they’re grown-ups, and we’ll talk about all the different foods they enjoy.

What Do Marmoset Monkeys Eat Throughout The Year: The Complete Diet

Marmoset monkey

Marmoset monkeys, those cute little primates from South America, have a pretty varied diet all year long. 

They’re good at adjusting to the different foods they can find in their tropical forest homes.

Fruits are a big part of what marmosets eat. 

They give them important stuff like vitamins, minerals, and sugars that keep them going, especially when they’re busy or having babies.

When fruits aren’t as easy to find, marmosets turn to tree sap and stuff that oozes out of trees. They’re pretty clever at using their sharp claws and teeth to get to it.

Apart from fruits and tree gums, marmoset monkeys also like to snack on insects such as spiders, crickets, and butterflies

They’re skilled hunters! Sometimes they’ll even gobble up snails, lizards, and bird eggs

That’s how adaptable they are in finding food in the dense forest.

Some marmosets also enjoy sipping nectar from flowers when they’re in bloom. 

It gives them important nutrients. But how much nectar they drink depends on when flowers bloom in their area.

Depending on the type of marmoset and where they live, they might also nibble on young leaves, nuts, seeds, and even mushrooms and truffles. 

They’re pretty good at making use of whatever food is available around them. 

What Do Baby Marmoset Monkeys Eat?

When baby marmoset monkeys are born until they reach about 4-6 weeks old, they mostly drink their mother’s milk. 

This milk is important because it gives them all the good stuff they need to grow and stay healthy.

If baby marmosets are taken care of by humans instead of their moms, they might drink a special kind of milk made for primates to make sure they still get all the right nutrients.

Once they hit 4-6 weeks old, they start trying out solid foods, but it’s a slow process. 

It’s best if a vet or someone who knows a lot about marmosets helps with this.

Soft fruits like papaya, mango, berries, and melon are yummy and easy for them to eat when they’re cut or mashed up. 

They can also start munching on small insects like crickets or mealworms for extra protein.

Vegetables such as sweet potato, green beans, and broccoli can be cooked until they’re soft and then given to the baby marmosets. This helps add more variety to their diet and keeps them healthy.

While they can have a bit of commercial marmoset food, it shouldn’t be the only thing they eat. 

They need to have a mix of different foods to stay healthy and happy.

As baby marmosets grow, they slowly learn how to find their food from watching their parents. 

This helps them become good at finding things to eat as they get older.

What Do Pygmy Marmoset Monkeys Eat?

The pygmy marmoset is known as the tiniest monkey around. You can find them in the South American rainforests, especially in the Amazon basin. 

These little monkeys mostly eat tree sap, gum, and resin that they get from trees high up in the forest. 

They also munch on different fruits, flowers, and insects they find around them. Sometimes they even eat small animals like spiders and tree frogs to round out their diet.

What Do Common Marmoset Monkeys Eat? 

Common marmoset monkeys, also called white-tufted marmosets, are pretty famous and have been studied a lot. 

They’re originally from Brazil and are known for the white tufts of hair on their ears and their long tails.

These marmosets eat a bunch of different things. They enjoy munching on fruits like berries, figs, and nectar from flowers. 

They also like snacking on insects such as crickets, grasshoppers, and caterpillars

Besides that, they use their special teeth and claws to get gum and sap from trees. 

Their diet is quite varied, including fruits, insects, tree gums, and even small animals.

What do Black-tufted Marmoset Monkeys Eat?

The black-tufted marmoset lives in the savannas and dry forests of central Brazil. 

You can spot them by the black tufts of hair on their ears and their longer tails compared to other marmosets.

These marmosets mostly eat fruits, insects, and tree gums. 

They enjoy snacking on berries, figs, and other small fruits found in their habitats. 

Bugs like spiders, crickets, and grasshoppers also make up a big part of their diet. 

They’re good at hunting, using their agility and making sounds to find and catch their prey.

Black-tufted marmosets usually live in pairs or small family groups. 

They work together when they’re looking for food, which helps them find more of it.

What do Wied’s Marmoset Monkeys Eat? 

Wied’s marmoset, also known as Callithrix kuhlii, stands out with its white forehead and black eye mask. 

These little monkeys live in different kinds of forests, from the main ones to the ones that grow back after being cut down.

Their diet is pretty much like other marmosets’. 

They eat fruits, bugs, small animals like lizards and frogs, and the stuff that oozes out of trees. 

When they eat fruits like berries and figs, they also help spread seeds around. 

Plus, by eating insects, they help keep their population in check. 

These marmosets are an important part of keeping the forest ecosystem balanced.

What do White-headed Marmoset  Monkeys Eat? 

The white-headed marmoset, alternatively referred to as the tufted-ear marmoset or Geoffroy’s marmoset, hails from Brazil. 

They make their homes in various types of forests, like lowland forests, sub-montane forests, and dry forest patches in desert areas.

These marmosets eat a bit of everything since they’re omnivores. 

They like insects such as beetles and grasshoppers, along with fruits, flowers, and small animals. 

They live in groups where multiple pairs have babies. They all pitch in to take care of the little ones and share food.

By eating insects, they help keep their numbers under control, and when they munch on fruits, they spread seeds around, which helps plants grow. 

They play an important role in keeping the forest healthy and balanced.

The food marmoset monkeys eat can change a bit depending on things like what’s available during different seasons and where they live. 

But overall, their basic food preferences and how they find food stay pretty much the same, no matter the type of marmoset monkey.

What Do Pet Marmoset Monkeys Eat?

Keeping marmosets as pets might seem interesting, but it’s really important to know that it’s not a good idea. 

In many places, it’s not just discouraged, it’s against the law because they need a lot of care that’s hard to provide.

If you’re thinking about getting or already have a pet marmoset, it’s essential to understand their diet. 

They need special attention to make sure they get all the right nutrients to stay healthy, and what they eat can vary depending on the type of marmoset they are.

1. Fruits and vegetables 

Fruits and vegetables are important for pet marmosets. 

They like fresh fruits such as apples, bananas, grapes, oranges, berries, and melons because they’re full of vitamins, minerals, and natural sugars that keep them healthy.

Besides fruits, it’s also a good idea to give them vegetables like leafy greens, carrots, sweet potatoes, green beans, and bell peppers. 

These veggies give them even more nutrients and fiber, which is good for their digestion.

2. Protein

Marmosets need protein to grow strong muscles and stay healthy. 

They can get protein from cooked eggs, a little bit of lean meats like chicken or turkey, and special pellets made just for them that have all the nutrients they need.

3. Insects

Bugs are a normal part of what marmosets eat in the wild, and sometimes you can give them to pet marmosets as a special treat. 

Live bugs like crickets or mealworms are fun for them and remind them of searching for food in nature. 

Just make sure the bugs have eaten well before giving them to your pet.

4. Commercial Primate Diets

You can find special diets made for marmosets in stores. 

These diets are designed to give marmosets all the important vitamins, minerals, and nutrients they need to stay healthy. 

It’s a good idea to include these diets in their meals.

5. Water

Access to clean, fresh water is crucial for marmosets to stay hydrated. 

Water should be provided in a shallow dish or a sipper bottle attached to their enclosure.

It’s important to talk to a vet who knows about exotic animals to get the right food advice for your marmoset because different marmosets might need different diets.

Don’t give marmosets human food or leftovers from your meals. It’s not good for them.

Remember, giving them the right food is just one part of taking care of marmosets. 

They need special homes, time with other marmosets, and fun things to do to be happy and healthy.

Before you get a marmoset, make sure to learn all about what they need and think about the problems with keeping exotic pets.

How Do Marmoset Monkeys Find Their Food?


Marmoset monkeys are good at finding food in their homes. 

They use their sharp eyes to look around for ripe fruits, insects, and other things they can eat. 

They also have a good sense of smell, so they can find the scent of fruits, flowers, and insects to help them find food. 

They talk to each other with sounds to let their group know when they find food or when there’s a lot of it around. 

They’re curious animals, so they explore their surroundings to find insects, tree sap, and other things to eat. 

They’re also good at using their hands and fingers to open fruits, get into insect homes, or take sap from trees. 

Young marmosets learn from older ones how to find food, watching and copying what they do. 

Marmoset monkeys use their senses, talk to each other, and explore to get food, changing how they look for it depending on what’s available in their forest homes.


In summary, the way marmoset monkeys eat shows how well they can adapt and thrive in different places. 

Whether they’re reaching for fruits way up in the trees or getting gum from tree bark, these small monkeys are good at finding the food they need all year round. 

If we know what they like to eat and make sure they have it, we can help take care of them better, whether they’re in the wild or living with people. 

This helps keep these amazing animals safe and healthy.


What should I feed my marmoset monkey?

It’s essential to feed your marmoset monkeys a balanced diet that mimics what they eat in the wild.
This includes a variety of fresh fruits and vegetables, lean proteins like cooked eggs or small amounts of chicken, and specially formulated primate pellets.
Make sure to consult with a veterinarian who has experience with exotic animals to get specific dietary recommendations for your marmoset.

Can marmoset monkeys eat bread?

Marmoset monkeys can technically eat bread, but it’s not a healthy or recommended part of their diet.
Bread is often high in carbohydrates and low in nutrients, which isn’t ideal for marmosets.
It’s best to stick to foods that are more natural and nutritious for them.

Can monkeys drink milk?

While monkeys might enjoy drinking milk, especially as infants, it’s generally not recommended to give them cow’s milk or other types of milk.
Many monkeys are lactose intolerant, which means they can’t digest lactose, the sugar found in milk, very well.
Instead of milk, it’s important to provide fresh water for monkeys to drink and ensure they have a balanced diet that meets their nutritional needs.

How much do marmoset monkeys cost?

The cost of a marmoset monkey varies depending on the breeder or dealer you purchase it from.
Marmosets that are sold as pets typically cost between $800 and $2000.
However, the price may be higher if you are looking for a specific type of marmoset or if you want one that has been bred for show.

How long do marmoset monkeys live?

The average lifespan of a marmoset monkey is 12-15 years.
However, some individuals have been known to live up to 20 years in captivity.
Marmosets that are well cared for and have access to proper medical care can expect to live a long and healthy life.
