From the dense rainforests of Osa Peninsula to the dry forests of Guanacaste, the country is home to four unique monkey species. Whether you’re an avid wildlife enthusiast or simply curious about Costa Rica’s furry acrobats, this guide has everything you need to know about monkeys in Costa Rica—and where to see them.
What Makes Monkeys in Costa Rica Special?
Costa Rica’s monkey species are an integral part of the ecosystem, playing crucial roles in seed dispersal and maintaining rainforest health. With their unique behaviors, vocalizations, and habitats, each species offers an extraordinary glimpse into the country’s natural beauty. Let’s dive into the details.
The Four Types of Monkeys in Costa Rica
1. Mantled Howler Monkey (Alouatta palliata)
General Characteristics
The Mantled Howler Monkey, commonly called “congo” in Costa Rica, is a robust and large New World monkey species. It measures between 70–140 cm (28–55 in) and weighs 3.6–7.6 kg (8–17 lbs), with males being larger than females. Its long, prehensile tail aids in climbing and feeding. The species is known for its dark, silky fur, which ranges from brown to reddish hues, with lighter tones on the sides. It is easily identified by its loud howls, made possible by an enlarged hyoid bone.
Habitat and Distribution
Mantled Howlers are found across Central America and northwestern South America, from southern Mexico to Ecuador. They inhabit a variety of forest types, including tropical rainforests, mangroves, deciduous forests, and secondary growth forests. In Costa Rica, they are distributed throughout the country except for Cocos Island.
They prefer lowland and mid-altitude regions (up to 900 meters/2,950 feet) and typically occupy the middle to upper canopy. Unlike some relatives, Mantled Howlers can adapt to fragmented forests and areas impacted by human activity, although they avoid flooded forests and coastal mangroves.
Behavior and Social Structure
Mantled Howlers are social animals living in groups of 6–23 individuals, with two to three adult males and several females. The dominant male controls mating rights. Group territories range from 10–60 hectares but can shrink to 3–7 hectares in over populated areas due to habitat destruction. They are generally peaceful, though males may become aggressive during intergroup encounters or when competing for mates.
Males and females leave their natal groups upon reaching sexual maturity. Females give birth to one offspring after a six-month gestation period, typically every two years.
Diet
Mantled Howlers are primarily folivores, consuming young leaves, fruits, and flowers. Leaves make up 48% of their diet, with fruits (42%) and flowers (10%) supplementing their intake. Young leaves are preferred for their higher protein content, and their diet varies depending on season and food availability.
In Costa Rica, they spend about 49% of their time eating leaves, 28% eating tropical fruits, and 22.5% consuming flowers. Key food sources include plants from families like Moraceae, Leguminosae, and Anacardiaceae. Mantled Howlers have been documented eating nectar and sometimes using their prehensile tails while feeding.
Vocalization
Their deep, resonant howls can be heard up to 2 km (1.2 miles) away. These calls are primarily used at dawn and dusk to establish territory and avoid physical confrontations, conserving energy.
Adaptability
Mantled Howlers have shown resilience to habitat changes, capable of surviving in fragmented forests and human-altered environments due to their folivorous diet and low-energy lifestyle. However, deforestation, illegal pet trade, and hunting pose significant threats.
Conservation Status
Although not currently endangered, their populations are under pressure from habitat loss and hunting. They are listed as a species of concern in several regions. Their adaptability has helped them maintain viable populations in areas like Costa Rica, where densities can reach up to 90 individuals per km².
Unique Facts
- Howler Monkeys are the loudest land animals in the world.
- Their diets and social behavior make them vital for forest ecosystems, as they aid in seed dispersal.
- Unlike most primates, Mantled Howlers have relatively small brains compared to their body size, weighing only about 55 grams.
Best Places to Spot Them in Costa Rica
Osa Peninsula, Guanacaste, Nicoya Peninsula, Monteverde, Arenal, and the Caribbean coast. Look for them lounging in trees along beaches like Tamarindo and Conchal.
2. White-Faced Capuchin Monkey (Cebus capucinus)
General Characteristics
The White-Faced Capuchin Monkey, also known as the “cariblanco” monkey, is a medium-sized New World monkey native to Central and parts of South America. Recognizable for its black body, pink face, and white fur on its neck and shoulders, it plays a vital ecological role as a seed and pollen disperser. They weigh between 1.5–4 kg (3.3–8.8 lbs), with an average length of 33.5–45.3 cm (13–18 in), excluding their prehensile tails, which can extend to 55.1 cm (22 in).
Habitat and Distribution
Capuchins are found in Central America (Honduras, Nicaragua, Costa Rica, and Panama) and the Pacific regions of Colombia and Ecuador. They thrive in a variety of forests, from evergreen and deciduous to secondary growth, and are highly adaptable. These monkeys prefer areas with abundant water during dry seasons and often inhabit regions with dense palm tree concentrations.
Behavior and Social Structure
Capuchins live in social groups ranging from 4 to 39 individuals, comprising both males and females. Females stay within their natal groups, while males migrate multiple times in their lifetime. The alpha male typically dominates group reproduction and ensures protection against predators and rival males.
Key behaviors include:
- Movement: They are arboreal but frequently descend to the forest floor, employing a variety of gaits such as running, climbing, and leaping.
- Social Dynamics: Females maintain close relationships with maternal relatives, while males form alliances to defend the group.
- Reproduction: Capuchins practice polygamous mating, with gestation lasting 5–6 months. Infants are highly dependent on their mothers but gradually explore independently after three months.
Diet
Capuchins are omnivorous, consuming a diet of fruits, insects, and small vertebrates. Fruits make up the majority (50–67%) of their diet, with frequent consumption of insects like beetles, spiders, and termites. They also use tools, such as stones, to access hard fruits and other food sources. Activity peaks during the early morning and late afternoon.
Predators and Threats
Common predators include large birds of prey (e.g., harpy eagles), snakes, and felines like jaguars and ocelots. Capuchins respond to threats by sounding alarms and often acting collectively for defense. They are also susceptible to parasites like ticks and gastrointestinal nematodes.
Conservation Status
Although classified as “Least Concern” by the IUCN, White-Faced Capuchins face challenges from habitat destruction and illegal wildlife trade. Their adaptability to various environments has helped them survive better than many other species. However, their populations require continuous monitoring to ensure their long-term survival.
Unique Facts
- They are one of the most intelligent New World monkeys, capable of using tools to forage for food.
- In some areas, they coexist and even collaborate with Squirrel Monkeys for mutual protection and resource sharing.
- Their ability to live in diverse habitats has made them one of the most resilient monkey species in Central America.

Their distribution is limited by habitat fragmentation and deforestation, which pose significant threats.
Key distribution areas include:
- Mexico: Veracruz, Oaxaca, Chiapas, and the Yucatán Peninsula.
- Central America: Guatemala, Honduras, Nicaragua, Costa Rica, and Panama.
- South America: Colombia, Ecuador, and parts of Peru.
Behavior and Social Structure
Spider Monkeys are social animals living in large groups of up to 100 individuals. These groups frequently split into smaller subgroups, a behavior known as fission-fusion, to optimize foraging and reduce competition for food. They are territorial, with males patrolling boundaries and sometimes engaging in confrontations with neighboring groups.
Key social traits include:
- Subgroups often consist of females with offspring and a few adult males.
- Males cooperate in defending territories and are typically dominant over females.
- Spider Monkeys communicate through vocalizations, making them relatively easy to locate.
Diet
Spider Monkeys are predominantly frugivores, with fruit making up the majority of their diet. They also consume young leaves, flowers, and occasionally seeds. Their diet varies by season and food availability, and their role as seed dispersers makes them critical for forest regeneration.
Key dietary components include:
- Fruits from genera such as Brosimum, Ficus, and Spondias.
- Young leaves and flowers, particularly during periods of low fruit availability.
Reproduction
Spider Monkeys have slow reproductive rates, with females giving birth to a single offspring every 2–4 years. Gestation lasts around 226–232 days, and infants remain dependent on their mothers for the first year of life. Sexual maturity is reached at 4 years for females and 5 years for males.
Threats and Conservation Status
Spider Monkeys are listed as Endangered by the IUCN and included in CITES Appendix I, meaning international trade is strictly regulated. The primary threats to their survival are habitat loss, hunting, and illegal pet trade. Their reliance on large forest areas makes them particularly vulnerable to deforestation.
Conservation efforts include:
