The paca is one of Costa Rica’s most elusive and least-photographed mammals. Spotting one requires patience, luck, and knowing where to look. Here is a practical guide to finding and photographing this remarkable rainforest rodent.

## What is the paca?

The Central American paca (Cuniculus paca) is the second-largest rodent in the world, weighing up to 14 kilograms (30 pounds) and measuring roughly 70 centimeters in body length. In Costa Rica, it inhabits lowland rainforests and cloud forest edges across the country, with the Osa Peninsula and Tortuguero canal region offering the best sighting opportunities.

Its coat is dark brown with distinctive rows of white spots along the flanks and a pale underside. The face shows bold white markings around the cheeks and eyes. The paca’s most recognizable feature is its almost comical appearance: a robust, barrel-shaped body perched on short legs, with a relatively small head and tiny ears. It moves with a distinctive waddle when startled.

This rodent is strictly nocturnal and highly secretive. It spends daylight hours in underground burrows or hollow logs and emerges after dark to forage alone. Males and females maintain exclusive territories centered on permanent water sources, which is why pacas are almost always found near streams, rivers, or wetlands within forested areas.

## Where to find pacas in Costa Rica

The paca’s distribution in Costa Rica spans the entire Caribbean lowlands and the Osa Peninsula. However, actually seeing one requires being in the right habitat at the right time.

The Osa Peninsula and Corcovado National Park represent the strongestholds of paca populations in the country. See also the Corcovado National Park photography guide for details on visiting Costa Rica’s premier lowland rainforest destination, which shares the same habitat that makes the Osa the best region for paca encounters.

The Tortuguero canal system and the waterways of the Gandoca-Manzanillo National Wildlife Refuge also support healthy paca populations. Here, pacas sometimes venture to the water’s edge at dusk to feed on fallen fruits that drop from overhanging trees.

In the cloud forests of the Caribbean slope, pacas occur at higher elevations as well, though they remain difficult to find anywhere.

The Caño Negro Wildlife Refuge and adjacent wetland habitats provide another strong option, as pacas frequently use the water’s edge as a travel corridor.

## Paca behavior and ecology

Understanding the paca’s behavior is essential for any photographer hoping to capture images of it.

Pacas are frugivores, meaning their diet centers on fallen fruit. A single paca can consume and disperse thousands of seeds each year through its droppings, making it a critical ecological agent in tropical forest regeneration. Figs, mangoes, and cecropia fruits rank among preferred food sources. When fruit is scarce, pacas supplement their diet with leaves, stems, and occasionally insects.

Each paca maintains a territory of 2 to 3 hectares, marked with scent glands and urine deposits along regular pathways. These well-worn trails often connect feeding trees to water sources. A burrow or den site is typically located on a hillside or elevated bank near water, providing protection from flooding.

Reproduction is slow by rodent standards. Females produce a single pup per litter, after a gestation of about 120 days. The young are relatively precocial at birth, already furred and able to move. This low reproductive rate means paca populations recover slowly from hunting pressure or habitat loss, which has made them increasingly rare in accessible areas.

Pacas communicate through foot-drumming , a loud thumping sound produced by striking the ground with the hind feet. This alarm call can alert other animals (and alert photographers) to a paca’s presence.

## Photography techniques

Photographing the paca presents significant technical and logistical challenges that separate it from most other Costa Rica wildlife subjects.

The fundamental problem is that pacas are strictly nocturnal in Costa Rica, emerging well after sunset when light levels are extremely low even in open forest clearings. A flash or a very fast lens becomes essential rather than optional.

A fast prime lens at f/2.8 or wider is ideal. Shooting at f/4 is possible but will require higher ISO values. Shutter speeds of 1/60 to 1/125 second will freeze a paca that is stationary, though any movement requires 1/250 second or faster. At ISO 1600 to 6400, modern full-frame or APS-C sensors produce acceptable results.

Using a flash with a diffuser can illuminate a paca at close range, though the harsh light may produce unnatural-looking images. Bounce flash off nearby foliage for a softer result, or use a lower flash power combined with a higher ISO to maintain a more natural atmosphere.

**Blind setup near fruit trees**

Wildlife photographers working in the Osa Peninsula sometimes set up camera blinds near known paca feeding sites. Positioning near a fruiting fig or mango tree along a confirmed paca trail and waiting motionless for hours before dark gives photographers a real chance of an encounter. The wait typically begins two to three hours before sunset to allow the area to settle.

**Autofocus considerations**

Modern camera autofocus systems struggle in very low light. Switch to manual focus and use live view magnification to achieve critical focus on the eyes. A headlamp on minimum power can briefly illuminate the subject for focusing, then be turned off before taking the shot.

**Water’s edge opportunities**

In Tortuguero and Gandoca-Manzanillo, pacas sometimes emerge at the water’s edge where overhanging fruit trees drop food into the canal. A boat positioned quietly downstream before dusk offers a chance of photographing a paca against the reflected light of the sky.

## Best regions for paca photography

The Osa Peninsula remains the premier destination for serious paca photography. The combination of dense populations, accessible forest trails, and the presence of photographers experienced with the species creates the best conditions. Lodge-based wildlife photography programs in the area sometimes include paca tracking as part of their itinerary.

Tortuguero offers a different approach, with canal-side paca encounters possible from boats. The Tortuguero wildlife photography guide covers the broader canal ecosystem and its mammal populations, including the paca.

For photographers without access to these remote areas, the Bijagua region near Tenorio Volcano National Park provides a more accessible gateway to lowland forest where pacas occur, and the longer-stay, lower-intensity approach of the area suits photographers who prefer to work at a relaxed pace.

## Conservation status

For photographers interested in other large Costa Rica mammals, the Baird’s Tapir photography guide covers another elusive rainforest species found in the same regions as the paca. The paca faces mounting pressure across Costa Rica. Hunting for bushmeat has reduced populations near populated areas to very low levels. Even in protected areas, forest fragmentation isolates paca populations and limits genetic exchange.

The species is legally protected in Costa Rica, but enforcement is difficult in remote areas. The primary conservation tool is habitat preservation: maintaining connected forest corridors between protected areas so that paca populations can sustain themselves.

For photographers, the ethical approach is straightforward: observe and photograph pacas without disturbing them. Do not use calls, bait, or flash at close range more than necessary. The goal is to document natural behavior in a way that contributes to understanding rather than stress.

## Frequently asked questions

**Are pacas dangerous to humans?**
No. Pacas are completely harmless and will flee if approached. They pose no threat and are not aggressive in any circumstance.

**Can you eat paca in Costa Rica?**
Historically, yes: paca meat was consumed in rural communities. It is now illegal to hunt pacas in Costa Rica, and the practice has declined significantly.

**What is the difference between a paca and an agouti?**
The agouti (Dasyprocta spp.) is smaller, leaner, and lacks the paca’s distinctive rows of white spots. The paca is nearly twice the size of an agouti and has a more robust, heavyset build. Both species are frugivorous forest rodents, but they occupy different ecological niches.

**What do paca photos typically look like?**
Most paca photographs show the animal either standing motionless on a forest trail or moving along a stream bank at night. Close-up portraits capture the bold facial markings and the texture of the spotted coat. The most striking paca images show one crossing a stream or sitting beside a fallen fruit in the spotlight beam.

**Is it possible to see pacas during the day?**
Almost never. Pacas are strictly nocturnal in Costa Rica. Any daytime sighting would be unusual and would typically involve a sick or displaced individual.

**Which months are best for paca photography?**
The dry season months of December through April offer better road conditions for reaching paca habitat in the Osa Peninsula and Tortuguero. However, the paca’s nocturnal habits mean that season matters less than spending sufficient time in the field after dark.
