Capybara or Ronsoco: Learn Where They Live in the Peruvian Jungle

The capybara, or ronsoco, is the largest rodent on the planet and, without a doubt, one of the star animals of the Peruvian Amazon. Seeing it up close—as it swims freely or rests on the riverbank—is an experience every nature lover should experience. If you plan to search for it, staying at a hotel in Puerto Maldonado will put you just minutes from the reserves and waterways where these social creatures thrive.

What is a capybara or ronsoco?

The Hydrochoerus hydrochaeris belongs to the same family as guinea pigs, but can weigh more than 60 kg. With its brown fur and flat snout, the capybara is recognized in the jungle by:

• Amphibian adaptation: partially webbed toes for swimming.

• Extreme sociability: groups of 10 to 20 individuals, led by a dominant male.

• Relative longevity: up to 12 years in the wild if you avoid predators such as jaguars and alligators.

Where does the capybara live in the Peruvian jungle?

The capybara, or ronsoco, requires nearby water year-round. In Peru, the best places to see it are:

• Tambopata National Reserve (Madre de Dios): Sandoval and Valencia lakes are home to large herds.

• Pacaya Samiria (Loreto): The flooded lakes and meanders host constant populations.

• Tahuamanu River and forested areas of Ucayali: right bank with sandy beaches where you can rest at sunset.

Thanks to its widespread distribution, the capybara in the rainforest is an indicator of healthy ecosystems and waters rich in floating vegetation.

What do capybaras eat?

These rodents are strictly herbivores. Their daily menu includes:

• Tender grasses and riparian grasses.

• Aquatic plants such as lilies and blowholes.

• Bark and fallen fruit during the growing season.

Their teeth grow continuously, allowing them to gnaw through fibrous materials without excessive wear. When capybaras find food in abundance in the jungle, they spend up to eight hours grazing before submerging to regulate their temperature.

When is it easiest to see capybaras?

Sightings depend on the season and time:

• Dry season (May–October): Water levels drop and capybaras concentrate on more accessible banks.

• Dry season (May–October): Water levels drop and capybaras concentrate on more accessible banks.

• Full moon nights: Some guides offer nighttime boat trips where the glowing eyes of a capybara or ronsoco are revealed in the flashlight.

Are ronsocos dangerous?

The ronsoco is docile and usually flees rather than attack. However:

• It will defend its young with strong bites if it feels cornered.

• It can transmit leptospirosis if its excrement is handled without caution.

• Reacts to stress: Getting too close or invading their escape route can cause canoeing accidents.

Maintaining your distance and following your guide’s instructions ensures a safe and responsible encounter with the capybara in the jungle.

Curiosities about the capybara

• Social bathing: they dive in groups to regulate temperature and eliminate parasites.

• Varied communication: they emit grunts, whistles and clicks to coordinate movements.

• Unexpected allies: birds like oxpeckers perch on capybaras and capybaras to feed on ticks, benefiting both.

• Long-term swimming: They can stay underwater for up to five minutes; their eyes and nostrils on the top of their skull facilitate periscope-style breathing.

• Organic farmers: By creating paths through reed beds, they allow other species access to flooded areas.

Observing the capybara, or ronsoco, in the wild is a discovery of a key component of the Amazonian ecosystem. These peaceful giants are a testament to the richness of our rivers and floodplain forests. Plan your trip with local naturalists and don’t forget to book a hotel in Puerto Maldonado to have the jungle—and its iconic capybaras—right at your doorstep.
