Monkey-watching in Colombia: nearly 40 species await you!

Imagine yourself in the Colombian jungle, the sun rising just above the canopy and a distant monkey howl echoing through the mist. In these lush forests, 38 distinct species of monkey share a unique tropical sanctuary. Under the thick foliage, guides and naturalists introduce amazed travelers to lively capuchins, mischievous titis and imposing spider monkeys, representatives of the three major families of Neotropical primates. This incredible wealth – with a dozen unique endemic species – illustrates the country’s incredible biodiversity.

Here, adventure rhymes with respect. Accompanied by local guides, you’ll watch silently for howler monkeys or the ballet of small tamarinds. Every encounter is furtive (but not always!) and respectful: we keep our distance and speak softly. This immersive and responsible trip promises an experience at the heart of Colombian nature, where you’ll discover the Amazon rainforest, the Andean forests and the mangroves like a true insider, and contribute to the preservation of these fragile ecosystems.

Apes VS primates: Primates are a large group of mammals that includes not only monkeys, but also lemurs, tarsiers, great apes (such as chimpanzees, gorillas or orangutans) and even humans. The term monkey refers to a sub-group of primates, generally arboreal, with a tail, such as capuchins or howler monkeys. Great apes, on the other hand, have no tails and are not classified as “monkeys” in biology, although they are very closely related. So, all monkeys are primates, but not all primates are monkeys.

Variety of monkey species in Colombia

Family Atelidae (prehensile-tailed monkeys)

Atelids are the largest monkeys in South America, characterized by a long, prehensile tail that serves as a “fifth limb”. They are strictly arboreal and live exclusively in the tropical forests (primary and secondary) of the neotropics. Their diet is primarily frugivorous (fruit), supplemented by leaves, flowers and nectar, with howler monkeys(Alouatta) being more folivorous. They are diurnal primates, often forming heterogeneous social groups; for example, Ateles marmosets have fission-fusion groups, while howlers can form harems in some species. Several atelids have remarkable behaviors (howlers with distant calls, or Ateles with highly agile brachiation).

Main species in Colombia:

• Ateles hybridus (brown spider monkey) – lives in the Magdalena Valley and the Andes.
• Ateles belzebuth (white-bellied spider monkey) – in the Amazon and Orinoco.
• Ateles geoffroyi (Humboldt spider monkey) – in the rainforests of the Colombian Pacific.
• Lagothrix lugens (Colombian woolly monkey) – Andes and Amazonia.
• Lagothrix lagotricha (brown woolly monkey) – Amazonia.
• Alouatta seniculus (Venezuelan red howler monkey) – widely distributed in the Amazon and Llanos.

These species live in tropical forests (dense or degraded) and sometimes at forest edges. They play a key role in seed dispersal.

Cebidae family (capuchins and squirrel monkeys)

The Cebidae include the capuchin monkeys (genera Cebus/Sapajus) and squirrel monkeys(Saimiri). They are highly social diurnal primates, forming large cooperative groups. They are omnivores: fruit and insects dominate their diet, supplemented by seeds, flowers and small vertebrates. Capuchins are known for their intelligence and use of tools (breaking nuts, opening shells). Morphologically, all cebids have long limbs and tails; only capuchins have a prehensile (weak) tail for grasping, while squirrel-noses (Saimiri) have a non-prehensile tail. These monkeys colonize a wide variety of forest habitats (dense forests, gallery forests, mangroves, dry forests up to 2000 m altitude).

Main species in Colombia:

• Cebus capucinus (Colombian white-faced capuchin) – found in the lowlands of the Colombian Pacific.
• Sapajus macrocephalus (large-skulled brown capuchin) – Amazonia.
• Cebus versicolor (Magdalena plains capuchin) – endemic to the middle Magdalena basin.
• Cebus cesarae (Rio Cesar capuchin) – endemic to the Cesar basin.
• Cebus malitiosus (Santa Marta capuchin) – Sierra Nevada de Santa Marta.
• Saimiri cassiquiarensis (Humboldt’s squirrel monkey) – Amazonia.

These arboreal primates form hierarchical bands (1 dominant male in capuchin monkeys, dominant females in squirrel monkeys). They play an ecological role in seed dispersal, and eat both fruit and small animals.

Family Callitrichidae (marmosets and tamarinds)

Callitrichids are very small primates (100-600 g): marmosets and tamarins. They are strictly diurnal and arboreal, living in cooperative family groups (polyandry or polygynandric reproduction). Morphologically, they have claws (nails are found only on the big toe) and almost always give birth to twins. Fathers and other group members play an active role in rearing the young (males often carry the young). Their diet includes insects, fruit and vegetable gums. They are found in a variety of lowland woodland habitats (tropical forests, riparian forests, secondary woods).

Main species in Colombia:

• Saguinus oedipus (white-headed tamarin) – endemic to Colombia’s northern Caribbean lowlands.
• Saguinus leucopus (white-footed tamarind) – Andean and Caribbean regions (endemic).
• Saguinus geoffroyi (Geoffroy’s tamarind) – Chocó.
• Callimico goeldii (Goeldi’s monkey) – Amazonian forests (northern Colombia).

These species mainly inhabit the canopy of rainforests. The white-headed tamarin is particularly threatened by deforestation and poaching.

Family Aotidae (nocturnal monkeys)

The Aotidae are the American nocturnal monkeys (genus Aotus), the only strictly nocturnal group of Neotropical primates. They are medium-sized (450-1250 g), with large heads and highly-developed eyes for night vision. Their long tails are not prehensile (not involved in grasping). Aotidae live in small monogamous family groups: a breeding pair and their offspring. They are highly arboreal and agile (jumping between branches), resting in tree cavities or nests during the day and moving around at night. Their habitat covers a wide range of low- to medium-altitude forest environments, from tropical rainforests to cloud forests, dry forests and mangroves. Their diet is omnivorous: fruits, insects, small vertebrates and gums make up the bulk of their food.

Main species in Colombia:

• Aotus griseimembra – Northern Andes.
• Aotus lemurinus – Caribbean lowlands and Andes (composite species).
• Aotus jorgehernandezi, Aotus zonalis, Aotus vociferans – found in the Andes and Amazon respectively.

With the exception of the two vulnerable species mentioned above, most marmosets are not endangered. However, the loss of their forest habitat is a serious threat.

Family Pitheciidae (monkeys-titis, sakis and uakaris)

The Pithecids include the tititis, saki and uakari monkeys. They are small to medium-sized primates, specialized in eating hard fruit. Their dentition features large canines separated by a diastema, and molars adapted to breaking hard fruit. Titis (genus Plecturocebus, ex-Callicebus) form close-knit monogamous pairs where the male helps with the breeding; sakis(Pithecia) and uakaris(Cacajao) live in multi-male/multi-female groups. Uakaris are distinguished by their almost naked face and very short tail. These monkeys occupy various types of tropical forest (submerged forests, riparian forests, wooded savannahs), from the Amazon plain to the Andean foothills. They are generally diurnal and arboreal. Their diet consists almost exclusively of large, hard-shelled fruits (e.g. Amazonian nuts) to eat the seeds, supplemented by leaves and insects depending on the season.

Main species in Colombia:

• Plecturocebus caquetensis (Caquetá titi) – endemic to the department of Caquetá.
• P. medemi (Putumayo black-orange titi) – South Colombian Amazon.
• Pithecia monachus (monk saki) – Amazonia.
• Cacajao melanocephalus (golden uakari) – Southern Amazon.

Sloths aren’t monkeys! They are arboreal mammals. They may look like monkeys, but they don’t belong to the primate family, but to the xenarthra family, like the armadillo and the anteater.

New-world monkeys vs. old-world monkeys

When we talk about monkeys, we often tend to lump everything into one big family. However, the primates known as “apes” are divided into two very different groups, separated for over 40 million years: New World apes, found exclusively in Central and South America, and Old World apes, found in Africa, Asia and, more rarely, Europe (southern Spain). This separation is the result of evolution and continental drift: an ancestor common to both groups evolved distinctly in different environments.

The nose: a revealing anatomical difference

New World monkeys, called Platyrrhini (from the Greek for “flat nose”), can be recognized by their blunt noses, with nostrils pointing to the sides. By contrast, Old World monkeys, called Catarrhini (“narrow nose”), have nostrils that are closer together, facing downwards. This anatomical detail, though seemingly trivial, is fundamental to scientists studying their evolution.

A tail that makes all the difference

In New World monkeys, the tail is often prehensile, i.e. capable of wrapping around branches like a fifth hand. This adaptation is very useful in dense tropical forests, where agility is vital (e.g. spider monkeys, howlers). In Old World monkeys, on the other hand, the tail is never prehensile. Some species, such as macaques and gibbons, have almost none at all.

Intelligence and social behavior

Old World monkeys are distinguished by greater social complexity. Baboons, for example, live in hierarchical groups, with well-defined social roles, alliances and even political conflicts. They also have more developed brains, which enhances their cognitive and social skills.
But New World monkeys, though smaller, are not devoid of intelligence. Capuchins, in particular, are capable of using tools, solving simple problems and even cooperating.

Teeth and diet

Even at the dental level, there are differences. American monkeys generally have 36 teeth (dental formula 2.1.3.3), while Old World monkeys have 32, like humans(2.1.2.3).
Their diet also varies: in America, monkeys are mainly frugivores, but also consume flowers, nectar or tree gum ( marmosets pierce the bark to collect the sap). In Africa and Asia, they also eat fruit, but often supplement their diet with leaves, insects and even small animals.

Some emblematic species

New World Monkeys:

• Howler monkeys: loud calls audible for several kilometers
• Spider monkeys: very agile with prehensile tails, the largest monkeys in the country
• Capucins: curious, intelligent and tool-users
• Squirrel monkeys, tamarins, marmosets: small, fast, very social

Old World Monkeys:

• Gibbons: masters of the sway, singers of the jungle
• Macaques: adaptable, even in urban environments
• Baboons: robust, highly social, hierarchical

Amazing facts about monkeys in Colombia

Here are 20 surprising and sometimes little-known facts about monkey species in Colombia (some of which are also found in neighboring countries)!

• The red howler monkey (Alouatta seniculus) is one of the loudest animals on the planet: its calls carry over 5 km through the forest.

• The pygmy marmoset (Cebuella pygmaea), found in southern Colombia, is the world’s smallest monkey: just 100 grams for a body length of 13 cm (excluding tail).

• The white-footed tamarin (Saguinus leucopus) is endemic to Colombia – found nowhere else in the world.

• The golden-tailed woolly monkey (Lagothrix lagotricha) has a dense, silky coat, earning it the nickname “cuddly monkey”. Yet it is critically endangered.

• Capuchin monkeys (Cebus capucinus) are able to use simple tools, such as stones, to break hard fruit – a rarity among South American primates.

• Spider monkeys (Ateles sp.) can swing over 10 meters from branch to branch thanks to their prehensile tail, sometimes nicknamed the “fifth hand”.

• The little-known titi monkey (Plecturocebus ornatus) is monogamous: it lives in faithful couples and emits soft vocalizations to reinforce its emotional bond.

• The emperor tamarin (Saguinus imperator), recognizable by its drooping white moustache, looks like a wise old man and is very popular in illustrations.

• Some monkeys in the Callitrichidae family (marmosets, tamarins) can give birth to twins almost systematically, which is rare among primates.

• In some indigenous Amazonian communities, the howler monkey is considered the guardian spirit of the forest, and its calls herald the changing seasons.

• The spider monkey’s tail is so muscular and precise that it can be used to pick berries or hang upside down while napping.

• The labiate tamarind (Saguinus labiatus), with its prominent pink lips, looks like… lipstick!

• Some monkeys in the Amazon can imitate the calls of birds or other monkeys, creating deliberate confusion to avoid predators.

• The brown woolly monkey (Lagothrix lagotricha) can travel up to 5 km a day in the canopy in search of ripe fruit.

• Species such as the saki monkey (Pithecia monachus) have such contrasting coats and faces (black and white) that they appear disguised – this camouflage confuses predators.

• Young tamarins are often carried by males or older brothers, not mothers, from the very first weeks – an example of shared parenthood.

• The white-breasted capuchin monkey is so intelligent that it can remember a path in the forest several weeks after having taken it.

• Some Colombian monkeys live at altitudes of over 2,000 meters, as in the Sierra Nevada de Santa Marta – a rare adaptation for primates.

• The howler monkey has a hollow hyoid bone in its throat, which acts as a sounding board to amplify its cries dramatically.

• Some species of tamarins live in tiny family groups of 3 to 5 individuals, with very strong social bonds and exemplary cooperation.

Threats and conservation

In Colombia, monkeys face multiple threats, many of them caused by human activity. Here are the main threats and some practical conservation measures, with specific examples:

Main threats to monkeys in Colombia

1. Habitat loss: Deforestation due to livestock farming, illicit crops, mining and urban expansion. Example: In the Colombian Amazon, thousands of hectares of forest are lost every year, affecting species such as the churuco monkey (Lagothrix lagothricha) and the critically endangered Caquetá titi monkey (Plecturocebus caquetensis).
2. Habitat fragmentation: When forest is divided up by roads, monocultures or dams, monkeys lose the opportunity to move around freely, which affects their reproduction and feeding. Example: In the Magdalena region, the habitats of howler and capuchin monkeys are isolated by farms.
3. Illegal trafficking and captivity as pets: Small monkeys, such as the titi monkey or the saimiri (squirrel monkey), are captured to be sold as pets, which is illegal and detrimental to their well-being. It is estimated that for every monkey successfully captured, between 5 and 10 die in the process.
4. Hunting and consumption: In some regions, monkeys are hunted as a source of food or for cultural beliefs. Example: In the Vaupés region, primate hunting is still part of local traditions and part of the indigenous way of life.

Conservation measures in Colombia

• Scientific research: Universities and NGOs carry out censuses, camera-trap monitoring and genetic studies to better understand monkey populations and their threats. Example: Researchers at the National University have identified new populations of little-known primates, such as the Andean nocturnal monkey (Aotus lemurinus).
• Protected areas and natural parks: The Amacayacu National Nature Park in the Amazon protects the habitats of several monkey species, including the endangered spider monkey (Ateles belzebuth). These areas limit deforestation and promote scientific research and ecotourism. The country has 60 protected natural areas, part of the National Natural Parks System (SPNN), covering a total of 22,982,013.14 hectares, or 11.10% of the national territory – including land and marine areas.
• Action plans for endangered species: The Colombian Ministry of the Environment, together with NGOs such as Fundación Proyecto Tití, is developing specific plans to protect vulnerable species. Example: The cabeciblanco titi monkey (Saguinus oedipus), endemic to Colombia’s Caribbean region, benefits from an active national conservation plan, including reforestation, environmental education and population monitoring.
• Environmental education and community involvement: campaigns in targeted rural schools teach the importance of primates (and other animals for that matter) and respect for wildlife. Some rural communities are involved in projects that replace hunting with community-based ecotourism, generating income from tourism as well as protecting wildlife.
• Corridors : Ecological corridors are set up to connect forest fragments, enabling monkeys to move and reproduce with other populations. Example: In the Montes de María, we are working to connect the habitats of the titi cabeciblanco monkey.

Cultural importance of the monkey in Colombia

Since pre-Columbian times, monkeys have been represented in various indigenous cultures in Colombia, although they are not an animal of major importance, unlike the mythical condor of the Andes. For example, in the Tairona civilization (Sierra Nevada de Santa Marta), gold figurines and ornaments in the shape of a monkey have been found, underlining the importance of this animal in their cosmovision.

Similarly, in the southwestern Andean region ( Pasto-Quillasinga cultures, present-day Nariño region), ceramics and decorative objects depicting monkeys are found; these are considered symbols of admiration and respect due to their resemblance to human beings. In the San Agustín culture (Huila department), monolithic sculptures show the monkey alongside other animals, and studies indicate that in this society, the monkey (along with the squirrel) was linked to fertility rituals.

Symbolism and traditional beliefs

The monkey has played a variety of symbolic roles in indigenous beliefs. In the Amazon region, myths are told of the monkey as a prankster or a master of human knowledge. They are traditionally attributed with qualities ofcunning or ingenuity: many Amazonian legends show the monkey as a mischievous character or the bearer of knowledge useful to humans. In addition, some monkeys – such as the howler monkeys of the rainforests – were considered spiritual beings or protectors of the forest.

In pre-Columbian religious contexts, the monkey may have been associated with fertility and transformation. In San Agustín, for example, anthropomorphic statuary often combines human and animal elements; the monkey is linked to fertility cults. In some Amazonian cultures in and around Colombia, shamans sometimes used the symbolism of the monkey in rituals, taking advantage of its agility and nocturnal nature for magical or trance purposes (according to oral tradition). In short, indigenous peoples valued the monkey both for its resemblance to man and for its link with the wilderness, regarding it as a spiritual intermediary in many original narratives.

Monkeys in folklore and popular tradition

In Colombia’s collective memory, legends and idiomatic expressions linked to the monkey have survived. Perhaps the most famous is the legend of Bogotá “s ‘Monkey of the Fountain’ (Mono de la Pila). This urban tale, which dates back to the 17th century, tells how a public fountain in the shape of a monkey was built in the main square to enable people to draw water. From then on, Bogotá” s mothers taught their children to accept their domestic duties with the expression: “Go complain to the monkey at the fountain“. The original statue of the monkey became a local emblem before being replaced by that of Bolívar; today, it is preserved in the National Museum as testimony to this founding myth.

In regional folklore, other stories and customs also make use of the figure of the monkey. In Andean and Amazonian areas, howler monkeys are seen as guardians of nature; their singular cry is said to herald climatic phenomena or frighten off intruders from the forest, protecting the woodland spirits. Folk festivals and carnivals often feature monkey costumes and masks depicting traditional stories or mythological characters, integrating the primate figure into the cultural spectacle.

Representation in contemporary art and culture

In contemporary Colombian art and popular culture, the monkey remains a living folk symbol. Numerous visual artists have reinterpreted indigenous iconography (including the monkey) in murals, sculptures and handicrafts. Traditional Andean music also features pieces inspired by monkeys: for example, the bambuco “Los Monos”, danced in regions such as Tolima and Antioquia, humorously evokes the playful behavior of these animals. In addition, environmental conservation andecotourism campaigns frequently use the image of the monkey (such as the howler monkey or the tití) to highlight Colombia’s biodiversity and the need to protect its forests.

Indigenous objects depicting monkeys can be admired in various Colombian museums. Although archaeological museums and the Gold Museum more often feature feline or amphibian figures, some pieces from the south and the Amazon region give pride of place to the monkey. These collections confirm that the monkey is a recurring figure in Colombian indigenous art and mythology.

Where to see monkeys in Colombia?

In Colombia, monkeys can be seen in several regions, particularly in protected areas rich in biodiversity. Nocturnal monkeys are, as you’d expect, the hardest to spot. But monkeys are also present in many other parts of the country. Any forest-covered area below 2,000 metres altitude is likely to be home to these fascinating animals!

Practical tips:

• Get up early: most diurnal monkeys are most active at dawn. To maximize your chances of seeing them, get up around 5 or 6 a.m.!
• Prefer guided tours: To increase the chances of observation without disturbing the animals, and to learn more about these animals and their environment.
• Respect ecotourism rules: no feeding or approaching too close.
• Luck: but don’t forget that observing monkeys or other animals in their natural environment is never 100% guaranteed: you also need a little luck.

Here are some of the best places to see primates in their natural habitat.

Amacayacu National Nature Park (Amazonas) – Heart of the Amazon jungle

Located near Leticia, this park is one of the best places in Colombia to observe a wide variety of primates, in the heart of the Amazon rainforest: spider monkeys, woolly monkeys, saimiri (squirrel monkeys) and pygmy marmosets. Excursions by pirogue and guided hikes are offered with local or indigenous guides. Accessible by plane from Bogotá, this is a top destination for immersion in the heart of Amazonia.

Fundación Maikuchiga (Amazonas) – Rehabilitation of monkeys in the forest

Located in the indigenous Tikuna village of Mocagua, around 1h30 from Leticia by boat on the Amazon River, the Fundación Maikuchiga is a pioneering center dedicated to the rehabilitation of primates that have fallen victim to illegal trafficking or captivity. Here you can observe churucos (woolly monkeys), spider monkeys, saimiris and marmosets, in their semi-natural environment. Founded with the help of biologist Sara Bennett and headed by Jhon Jairo Vásquez, a former hunter turned passionate conservationist, the foundation has enabled a large part of the local community to make the transition from hunting to responsible tourism.

Be careful not to confuse this with “Isla de los Micos”, another site close to Leticia, which we didn’t visit, but were advised against by local guides. According to several accounts, this is more of a tourist attraction based on the exploitation of monkeys, with no real conservation objective, but rather motivated by profit and entertainment.
