Animals in Uruguay
Wildlife in Uruguay
Uruguay is a small South American country of rolling grasslands, low hills, rivers and Atlantic beaches. Native mammals such as armadillos, opossums, small deer, capybaras and hares use pastures, field edges and river margins. Wetlands and lagoons hold herons, storks, shorebirds and other water birds, while sandbars and rocky islands just offshore are resting places for seals and sea lions. Out at sea, whales and dolphins follow seasonal routes along the coast. Because many rural areas keep a mix of grazing land, marsh and scattered trees, it is still possible to see wildlife quite close to farms and small towns.
National Animal of Uruguay
The southern lapwing, known locally as the tero, is widely treated as the national bird of Uruguay. It lives in open fields, river banks and pastureland, where it walks on the ground searching for insects and other small animals. When nesting, it defends its territory with loud calls and low flights, often warning other birds and nearby livestock of intruders. Its presence is common around farms, roadsides and sports fields, so many people in Uruguay recognise it by sight and sound from everyday life.
Most Dangerous Animals in Uruguay
Uruguay is generally seen as a country with few dangerous animals, but some species still require caution in certain places. In warm wetlands and slow river sections, caimans may rest in shallow water or on muddy banks and can react if people or dogs get too close. In grasslands and stony ground, venomous pit vipers of the lancehead group are a risk when walking through tall grass or moving logs and rocks. At sea, large sharks such as tiger, hammerhead and great white sharks, together with orcas, are the main top predators along the coast. Keeping distance from wildlife, watching where you step and following local advice are usually enough to avoid serious problems.
Top 10 Animals in Uruguay
Two animals that often appear in top ten style lists for Uruguay represent very different parts of the country. The capybara is a large semi aquatic rodent of wetlands and river margins, where it rests in groups, feeds on grasses and often escapes into the water when disturbed. The great white shark belongs to the colder Atlantic waters offshore and is known from records and occasional reports along the coast. Together they show how Uruguay links calm inland marshes with a much more powerful marine environment only a short distance away.
Hare
Introduced to South America in the late nineteenth century, the European hare reached Uruguay and adapted well to its open grasslands and agricultural plains, known locally as pampas. It is now common across much of the country and is considered an invasive species, competing with native wildlife for food and space. Despite its status as an introduced animal, it is widely hunted for sport and for its meat. Its IUCN status is Least Concern.
Armadillo
The nine banded armadillo and the southern long nosed armadillo are both found in Uruguay, primarily in grasslands, scrublands, and forest edges across the country. Uruguay represents the southeastern limit of several armadillo species' ranges. The animals are well known locally and historically were hunted for food and for their shells, which were used to make traditional musical instruments called charangos. Road mortality is a significant threat given Uruguay's dense road network and expanding agricultural frontier.
Capybara
In Uruguay, capybaras are found near rivers, streams, and wetlands throughout the country, with notable populations along the Uruguay and Negro rivers. They are the largest native rodent in Uruguay and a familiar sight in riparian habitats. Listed as Least Concern by the IUCN, the species is legally protected in Uruguay. Habitat loss from agriculture and urban expansion near waterways remains the primary pressure on local populations.
Opossum
Uruguay marks roughly the southern limit of the opossum's natural range in South America. They are found mainly in the northern and northeastern departments, where gallery forests along rivers and patches of native woodland offer suitable habitat. Sightings near farms and suburban areas are not unusual. Populations are small compared to tropical countries but steady. The species holds Least Concern status in Uruguay.
Pampas Deer
In Uruguay, the pampas deer inhabits open grasslands and is considered a symbol of the country's native wildlife. It favors undisturbed fields and gentle slopes across the interior. Intensive agriculture and the expansion of livestock farming have reduced its range considerably. Conservation efforts focus on preserving the native grasslands of Uruguay, which represent some of the most important remaining habitat for this species in the region.
Margay
Uruguay sits at the southern edge of the margay's range, where sightings are extremely rare. The cat is associated with the gallery forests along river corridors in the north of the country, near the Brazilian border. Its presence in Uruguay is not well documented, and any population here is likely very small. As one of the most arboreal of all wild cats, it depends entirely on intact forest to survive. The IUCN lists it as Near Threatened.
Caiman
Uruguay represents the southernmost limit of the caiman's range in South America. The broad-snouted caiman has been recorded in the northeastern wetlands near the border with Brazil and Argentina, particularly around the Cuareim and Negro river systems. Populations here are small and considered vulnerable to habitat disturbance. Conservation attention at the national level remains important to ensure the persistence of caimans at this edge of their natural range.
Yellow Anaconda
The yellow anaconda reaches the southern edge of its range in northeastern Uruguay, in the wetland areas near the borders with Argentina and Brazil. It has been recorded in the marshes and riverbanks of the region, though encounters are rare. It feeds on fish, birds and small mammals in the flooded lowlands of the Artigas department.
Lancehead
Uruguay marks the southern limit of lancehead distribution in South America. Bothrops alternatus, known as the crossed pit viper, is the main species present, found in grasslands, wetlands and gallery forests along river corridors. It is the most medically significant snake in the country. Though encounters are less frequent than in tropical countries to the north, agricultural and rural workers in departments such as Rivera and Artigas should remain cautious.
Black browed Albatross
Along Uruguay's Atlantic coastline and over the Río de la Plata estuary, the black browed albatross appears regularly during the austral winter and spring. It is drawn to these productive waters by abundant fish and squid. Uruguayan longline and trawl fisheries operating in the southwestern Atlantic pose a significant bycatch risk to the species, and local conservation programs have worked with the fishing industry to reduce accidental capture.
Barn Owl
The barn owl is one of the most widespread birds of prey in Uruguay, found across the entire country in open farmland, grassland, and the outskirts of towns and villages. It nests in old farm buildings, eucalyptus trees, cliff faces, and hollow trees, and hunts rodents at night. Uruguay's open pastoral landscape, dominated by cattle and sheep ranching, provides extensive hunting habitat across virtually every department. It is one of the most commonly encountered raptors in the country and is valued by farming communities for naturally controlling rodent populations.
Peregrine Falcon
In Uruguay, the peregrine falcon is present mainly during the austral winter months, when birds from Patagonian breeding populations move northward. It frequents the open grasslands of the Pampas, the Atlantic coast, and the wetlands along the Río de la Plata estuary. These wide, open spaces suit its hunting style perfectly. Local birdwatchers regularly record the species at coastal sites around Montevideo and the Rocha department.
Hornero
Uruguay's rolling grasslands and farming countryside make it one of the best places in South America to observe the rufous hornero. The species is abundant across the entire country, nesting on fence posts, trees, and buildings in both rural and urban settings. It forages confidently on open ground and is a beloved part of everyday life for many Uruguayans. Its IUCN status is Least Concern.
Monk Parakeet
The Monk Parakeet is one of the most recognizable birds in Uruguay, present across the entire country from rural pastures to city parks in Montevideo. It builds its characteristic large stick nests on trees and power lines throughout the year. Uruguayans commonly call it the cotorra, and it is deeply embedded in everyday life as a familiar and often noisy neighbor. IUCN Status: Least Concern.
Rhea
The greater rhea is the largest bird in South America, standing up to 1.5 metres tall. In Uruguay, it lives in open grasslands and farmland across much of the country, and is one of the most recognisable birds on the Uruguayan plains. Though it cannot fly, it runs at speeds of up to 60 kilometres per hour. Hunting and habitat loss have reduced its numbers over time. Its IUCN status is Near Threatened.
Southern Lapwing
In Uruguay, the southern lapwing is one of the most familiar birds in the landscape, found across the rolling grasslands, farmland, river edges, and urban parks that define much of the country. Locally known as the tero, it is celebrated for its fierce defense of its nest and its constant, piercing calls. Its IUCN status is Least Concern, and it is abundant throughout Uruguay.
Southern Caracara
Uruguay's rolling grasslands and wetlands make ideal habitat for the southern caracara, and it is one of the most familiar raptors in the country. It strides through cattle pastures and open fields, feeding on carrion and insects, and often follows farm machinery to catch prey disturbed by the blades. Uruguayans know it well, and its tolerance of human activity has helped it thrive across both rural and suburban landscapes. Its IUCN status is Least Concern.
Rufous bellied Thrush
Uruguay sits at the southern edge of the rufous bellied thrush's range, and the bird is nonetheless widespread and common here. It inhabits riparian forests along the Uruguay and Negro rivers, as well as the gallery woodlands of the interior. In Montevideo and other cities it has settled comfortably into parks and gardens. Its bold song carries well across open ground, making it one of Uruguay's most noticed everyday birds.
Black necked Swan
The black necked swan is a well known resident of Uruguay's coastal lagoons, wetlands, and estuaries, particularly along the Atlantic coast and in areas such as Laguna de Rocha. Pairs nest among emergent vegetation, and cygnets are often seen riding on the backs of their parents. Wetland degradation and water pollution pose ongoing threats to local populations. The IUCN lists the species as Least Concern.
Blue Whale
The southwestern Atlantic waters off Uruguay form part of a migratory corridor used by blue whales moving along the South American coastline. The nutrient-rich currents of the Río de la Plata region and the broader South Atlantic support the krill populations that sustain these animals during transit. Regional cooperation on marine conservation is key to protecting individuals that travel through Uruguayan waters.
Fur Seal
Isla de Lobos, off the coast of Uruguay, hosts one of the most important South American fur seal colonies in the region. Tens of thousands of individuals gather there to breed each year. Uruguay has established this island as a protected nature reserve, limiting human access during the breeding season. Despite this protection, interactions with local fisheries and occasional pollution events remain concerns for the population.
Humpback Whale
Humpback whales are observed in the South Atlantic waters off Uruguay, where the Río de la Plata estuary meets the open ocean. They pass through this region during their migrations between Antarctic feeding grounds and tropical breeding areas further north. Uruguay's coastline offers occasional sightings, particularly during the southern winter months. These whales can grow up to 16 metres in length and weigh as much as 40 tonnes. The IUCN lists the species as Least Concern.
Orca
Uruguay's coastline along the Río de la Plata estuary and the South Atlantic places it within the range of orcas that patrol the waters of the southern cone of South America. Sightings have been recorded off the Uruguayan coast, often linked to the movement of prey species. The South Atlantic supports healthy marine ecosystems, and orcas here form part of a broader regional population shared with Argentina and the Falkland Islands.
Bottlenose Dolphin
Along the Uruguayan coast, bottlenose dolphins frequent the Río de la Plata estuary and the Atlantic shoreline, where they forage in productive, nutrient-rich waters. They are often observed near the coastal cities of Montevideo and Punta del Este. Interactions with artisanal fishing operations have been documented, raising concerns about bycatch. The IUCN lists the species globally as Least Concern.
Common Dolphin
Common dolphins are found in the South Atlantic waters off Uruguay, including the productive Río de la Plata estuary region and the open coastal shelf. They often travel alongside other small cetaceans in these nutrient rich southern waters, feeding on anchovies and other schooling fish. Interactions with artisanal fishing operations have been recorded, and researchers at Uruguayan universities have studied their distribution along this stretch of coastline.
Southern Right Whale
Uruguay's Atlantic coastline, particularly the area around Peninsula Valdés and the waters near Cabo Polonio, occasionally hosts southern right whales during their seasonal movements. These whales travel through the southwestern Atlantic as part of broader migratory routes shared with neighboring Argentina. Conservation efforts across the region have helped the population grow steadily. The species is currently listed as Least Concern by the IUCN.
Sperm Whale
The South Atlantic waters off Uruguay, where the warm Brazil Current meets the cooler Malvinas Current, create highly productive marine zones that attract sperm whales. This upwelling region supports abundant squid populations, a key food source for these deep diving whales. Both males migrating south and mixed groups have been recorded in Uruguayan waters. The IUCN classifies the sperm whale as Vulnerable.
Tiger Shark
Tiger sharks reach the southern limit of their range in the Atlantic near Uruguay, where the mixing of warm and cold currents creates a productive marine environment. Sightings are less frequent here than in tropical waters to the north, but the species has been recorded in Uruguayan waters. Uruguay has taken steps to regulate shark fishing and improve data collection on elasmobranchs. The tiger shark is listed as Near Threatened by the IUCN.
Hammerhead Shark
Hammerhead sharks venture into the cooler waters of the South Atlantic along Uruguay's coastline, including the Río de la Plata estuary zone. They follow migratory prey through these productive seas. Uruguay's fishing industry has historically contributed to declines in shark populations in the region, though growing regional cooperation in South America is working to improve protections for species at risk.
Great White Shark
The great white shark has been recorded in the South Atlantic waters off Uruguay, where the cool, nutrient-rich currents of the Río de la Plata region and the southern Atlantic create suitable habitat. Uruguay shares this marine range with neighboring Argentina and Brazil. Though sightings are infrequent, the species is part of the broader South Atlantic population that researchers continue to study to understand migration patterns and population health.
