The moustached tamarin (Saguinus mystax) is a small monkey from the Americas. It's a type of tamarin. This monkey gets its name from the white hair around its mouth, which looks just like a moustache! Like all New World monkeys, you can only find them in parts of Central and South America.

Types of Moustached Tamarins
There are three different kinds, or subspecies, of the moustached tamarin:
- Spix's moustached tamarin
- White-rumped moustached tamarin
- Red-capped tamarin
What Moustached Tamarins Look Like
Moustached tamarins are small monkeys. They usually weigh about 500 to 600 grams, which is less than a bag of sugar. Their bodies are about 30 to 92 centimeters long. Female tamarins are usually a bit bigger than males. These monkeys can live for about 20 years.
They are easy to spot because of the white, curly hair around their mouths. This hair looks just like a moustache! Their faces are flat, and their eyes are shaped like almonds. They have large, furry ears and long, silky body hair. Their bodies are brownish-black, but their moustache and nose are white.
Moustached tamarins have special claw-like nails called tegula on all their fingers and toes, except for their big toe. These claws help them hold onto trees easily while they eat. Their front teeth (incisors) are good for cutting food. They are smaller than their pointy canine teeth. Unlike most New World monkeys, moustached tamarins cannot use their thumbs to grasp things. They also do not have a tail that can grab things.
How Moustached Tamarins See Colors
About 60% of female moustached tamarins can see a wide range of colors. This is called trichromatic vision. It means they have three types of color sensors in their eyes. This lets them see greens, blues, and reds. Most humans and Old World monkeys also have this type of vision.
The other moustached tamarins, including all males, have dichromatic vision. This means they can only see two main colors. Being able to see more colors helps female tamarins find and identify fruits more easily. It also helps them choose leaders for their groups.
Where Moustached Tamarins Live
Moustached tamarins live in the tropical rainforests of Brazil, Bolivia, and Peru. They prefer dry, high-up forests in the Amazon lowland. They mostly stay in the higher branches of trees. A group of moustached tamarins usually uses an area of about 25 to 50 hectares as their home.
What Moustached Tamarins Eat
Moustached tamarins eat many different things. They are omnivorous, which means they eat both plants and animals. They especially love fruits (making them frugivorous) and insects (making them insectivorous). Their diet mainly includes fruits, nectar, tree sap (called exudates), and small animals without backbones (like insects). They also eat small animals with backbones, such as lizards and frogs.
They eat tree sap more during the dry season and early wet season. This is when other foods are hard to find. Tree sap gives them important nutrients and minerals. This helps them stay healthy, especially when they eat a lot of insects, which can be low in calcium.
Moustached tamarins are very good at finding food. They eat whatever is available in their area. They choose trees that have a lot of nectar, even if they are far from their home. More nectar means they can eat for longer. They have amazing spatial memory, which helps them remember where fruit trees are. This memory helps them find food easily and saves energy.
Moustached tamarin monkeys are very important for the forest. When they eat fruits, they spread the seeds. This helps new plants grow and keeps the forest healthy. Because they eat so many different kinds of fruits, they help spread many different types of seeds.
Sharing Their Home with Other Monkeys
Moustached tamarins protect their territory. However, they sometimes share their space with groups of brown-mantled tamarins (Saguinus fuscicollis) and Geoffroy's saddle-back tamarin (Leontocebus nigrifrons). These different monkey species can live together because they move differently, hunt in different ways, and eat different foods. They also live in different parts of the forest. This means they don't compete for the same things. Sharing territory helps both groups avoid predators. More eyes and ears mean better protection for everyone.
Moustached Tamarin Behavior
Moustached tamarins live in trees (they are arboreal). They are active during the day (they are diurnal). They are also precocial, meaning their babies are quite developed at birth. Tamarins walk and run on all fours, like squirrels. They use their claws to hold on tightly to branches.
They use three main ways to move around:
- They often use symmetrical quadrupedalism, which means moving all four limbs at the same time in a balanced way.
- They also use asymmetric quadrupedalism, where their limbs move differently.
- They leap a lot. The way they leap depends on where they are in the forest.
- In the lower parts of the trees, they make short, quick jumps (1 to 2 meters) from one tree trunk to another.
- They also make "bounding" leaps to cross between trees that are not connected. These jumps can be up to 2 meters long.
- In the high treetops, they make "acrobatic" leaps. These are longer jumps, sometimes 5 meters or more. They use their tails to slow down before landing on another tree.
Moustached tamarin monkeys choose thick, leafy areas to rest and sleep. This helps them hide because their small size makes them an easy target for predators. Their main way to stay safe is to avoid being noticed. Their predators include eagles and other birds that hunt, snakes, tayras, jaguarundis, ocelots, and other wild cats.
Social Life and Communication
Moustached tamarins groom each other to build friendships. They use their claws to untangle hair and their teeth and tongues to remove dirt and parasites. Not all tamarins groom equally. How much grooming they give or get depends on their social standing in the group.
They also use scent to mark their territory and talk to each other. Females mark their scent more often than males. This is because scent marking is also used to choose a mate. There are three ways they mark their scent: circumanal marking, suprapubic marking, and sternal marking. Circumanal marking is the most common.
Visual communication includes facial expressions, gestures, "tonguing," and "head-flicking."
- "Tonguing" is when a tamarin moves its tongue across its lips.
- "Head-flicking" is when a tamarin quickly moves its head upwards.
These two actions often happen together. They are used to show recognition, curiosity, or anger.
Group Life
Moustached tamarin groups usually have 4 to 8 members, not counting babies. Each group typically has 1 or 2 adult females. However, some groups have been seen with up to 15 individuals. Sometimes, a tamarin might even be found alone.
Every morning, tamarin groups leave their sleeping spot to find food. They don't all eat at the same time. One adult will watch for predators while the others eat. At night, they go back to thick, leafy areas to sleep safely from predators.
Group Conflicts
Sometimes, groups of moustached tamarins fight with neighboring groups. This often happens when there isn't enough food, especially near big fruit trees. They might have "vocal battles" with loud, high-pitched calls. This happens when groups are about 25 meters or more apart.
Fights can also be more aggressive. These fights can include alarm calls, looking at each other, scent marking, and chasing. Adult males might attack, making loud noises. Younger tamarins might chase each other. After the fight, there is usually a calm period. Both groups then look for food, and younger tamarins might check out the other group for mating chances. More aggressive fights happen during the breeding season.
How Moustached Tamarins Talk
Moustached tamarins use different sounds to talk. These sounds help them tell each other apart, plan group movements, and make sure everyone is together. If a tamarin gets separated, it will make calls that last 2 to 3 seconds. These calls are short, repeated sounds that help others find them. In the morning, they call to each other to decide where to go for food that day. Young tamarins also make sounds when they play and chase each other.
Reproduction and Life Cycle
The breeding season for moustached tamarin monkeys is from November to March. During this time, the oldest female in the group is usually the one who has babies. Females are ready to mate for about 17 days. Their pregnancy lasts about 145 days.
Other members of the group help take care of the babies. This allows the female to have babies more than once a year. The oldest female often gives birth to twins. This is because she releases more than one egg during each breeding cycle. At birth, the twins can be up to a quarter of their mother's size!
Females can start having babies when they are about 480 days old. Males can start reproducing when they are about 540 days old. Both males and females usually move to a different group when they become adults. This helps prevent inbreeding, which is when closely related animals have babies.
Moustached tamarins have different mating systems. Sometimes one female mates with many males (called polyandry). Sometimes one male mates with many females (called polygyny). And sometimes both males and females have multiple partners (called polygynandry). Mothers often get help from 4 or 5 other group members to raise their babies. In groups where one female mates with many males, the main male allows other males to stay and help care for the babies. If there aren't enough helpers, sometimes the mother might even harm her own babies.
Protecting Moustached Tamarins
The number of moustached tamarin monkeys is going down. However, the IUCN red list says they are of "least concern." This means they are not in immediate danger of disappearing. They have shown that they can live in places where humans have changed the habitat. They can also get used to changes in their environment.
Habitat destruction is still a big threat to them, just like for all animals in the Amazon rainforest. But their ability to adapt gives hope that this won't severely affect their numbers.
Why Moustached Tamarins Are Important to People
Moustached tamarin monkeys are important for science and medicine. Like other tamarin species, they are often used in biomedical research. For example, they helped in creating the hepatitis A vaccine.
