Animals in Paraguay
Wildlife in Paraguay
Paraguay sits between humid forest in the east and the dry Chaco in the west, with broad rivers, marshes and grasslands in between. In the forested areas, monkeys, small wild cats, armadillos, anteater type mammals, deer and many birds use tree cover and riverbanks. In the Chaco, tougher mammals, reptiles that cope well with heat and sparse trees, and ground feeding birds are more common. Along rivers and wetlands, capybaras, water birds and reptiles depend on seasonal floods. This mix of regions in a relatively small country produces a quiet but very varied wildlife.
National Animal of Paraguay
The bellbird is a medium sized forest bird and is recognized as the national bird of Paraguay. Males are mostly pale with a strong bill and a thick neck, and they perch high in the canopy to deliver a very loud, bell like call. Females are more camouflaged and spend more time hidden among leaves. Bellbirds feed mainly on forest fruits and help spread seeds as they move from tree to tree. Their powerful voice is often heard long before the bird itself is seen.
Most Dangerous Animals in Paraguay
In Paraguay, the animals that can cause serious harm are mostly large predators and snakes, especially in remote forest, Chaco scrub and wetland areas. Jaguars and cougars are strong cats that may react with force if surprised at close range. Along rivers and ponds, caimans and large constricting snakes such as anacondas and big boas can be dangerous if disturbed. Venomous pit vipers, including rattlesnake and lancehead types, are another risk in warm rural zones, where they may rest in tall grass or among fallen branches. Walking with care, wearing proper footwear and keeping distance from wildlife greatly lowers the chance of accidents.
Top 10 Animals in Paraguay
Animals often linked with Paraguay’s wildlife show how different its main regions are. In forest and river zones, jaguars, other wild cats, capybaras, deer, armadillos and anteater like mammals share space with toucans, parrots and the bellbird in the trees above. In open grasslands and drier scrub, maned wolves, rheas, ground doves and birds of prey are more typical. Together these groups give a simple picture of how forest, wetlands and Chaco landscapes each add their own set of species to the country.
Ocelot
In Paraguay, ocelots are found in the Atlantic Forest remnants of the eastern region and in the dry forests and scrublands of the Gran Chaco. The Chaco is one of South America's largest dry forest ecosystems and supports a range of wildlife, including this adaptable cat. Deforestation rates in Paraguay are among the highest in the world, making habitat loss a pressing concern for ocelots and many other species.
Hare
The European hare has been recorded in Paraguay, where it reaches the northern edge of its introduced South American range. It is found in open grasslands and agricultural zones, habitats that mirror the conditions it favours elsewhere on the continent. Its populations in Paraguay are less studied than in neighbouring Argentina or Brazil, but the species is considered established in suitable lowland areas where open terrain and farmland are available.
Cougar
In Paraguay, the cougar inhabits the Chaco, one of South America's largest dry forests, as well as the Atlantic Forest remnants in the eastern part of the country. It preys on deer, armadillos, and peccaries across these contrasting landscapes. The Atlantic Forest in eastern Paraguay has lost most of its original cover, making the Chaco increasingly vital for the species. The cougar is listed as Least Concern but faces ongoing habitat pressure.
Anteater
The giant anteater is found in Paraguay's Chaco region and the wetlands of the eastern part of the country, where it inhabits open savannas, gallery forests, and floodplains. Populations have declined due to agricultural expansion, wildfires, and road mortality. The species is legally protected in Paraguay and conservation programs in the Chaco are working to stabilize remaining populations.
Armadillo
Paraguay hosts several armadillo species, including the nine banded armadillo, the southern three banded armadillo, the giant armadillo, and various hairy armadillos found in the Chaco. The dry Chaco in the west supports a particularly high diversity of species adapted to arid and dry conditions. The southern three banded armadillo, one of the few that can roll into a complete ball, is found here and is classified as Near Threatened due to habitat loss. Hunting for meat and traditional uses of the shell remain common across rural Paraguay.
Capybara
In Paraguay, capybaras are found throughout the country, with particularly high densities in the Pantanal region of the Alto Paraguay Department and along the Paraguay and Paraná rivers. They thrive in seasonally flooded grasslands and wetlands. Listed as Least Concern by the IUCN, the species is an important part of Paraguay's wetland ecosystems, though habitat degradation from cattle ranching affects parts of its range.
Jaguar
In Paraguay, jaguars survive mainly in the Chaco region and in forests along the banks of the Paraguay River. Significant deforestation for cattle ranching has pushed these animals into increasingly fragmented habitats. The Pantanal, which extends into northwestern Paraguay, provides some of the most important remaining habitat for the species. Conservation organizations are working with local communities to reduce retaliatory killings by farmers. IUCN status: Near Threatened.
Opossum
Paraguay lies within the natural range of several Didelphis species, which occupy both the humid eastern forests near the Paraná river and the drier Chaco region to the west. Known locally as "mbicuré," opossums are a recognized part of Paraguayan forest life. They are comfortable foraging near human settlements and are often spotted after dusk near fruit trees or garbage. Their conservation status is Least Concern.
Tapir
Paraguay is home to the South American tapir, which lives in the forests and wetlands of the eastern region as well as in the dry Chaco to the west. Rapid deforestation, particularly in the Gran Chaco, has reduced available habitat significantly in recent decades. Tapirs are also hunted for their meat in some rural areas. Efforts to protect remaining forest patches are essential for the species to survive in Paraguay.
Maned Wolf
In Paraguay, the maned wolf is found in the Cerrado and humid grasslands of the eastern region, as well as parts of the Chaco. It is a solitary animal that covers great distances each night in search of food. Deforestation and the expansion of farmland have significantly reduced its range within the country. It is considered vulnerable in Paraguay, and protected areas are critical to its continued presence.
Marsh Deer
The marsh deer lives across the wetlands and river floodplains of Paraguay, where it feeds on grasses, aquatic herbs, and the stems of plants that grow at the water's edge. Adults can weigh over 150 kg and cross rivers with ease. Drainage of wetlands and disease spread by cattle have taken a heavy toll on local populations. The IUCN considers the species Vulnerable, with numbers continuing to decline across much of its range.
Pampas Deer
Paraguay's pampas deer live in the grasslands and open savannas of the eastern region, as well as in parts of the Chaco. The species is active mainly at dawn and dusk, feeding on grasses, herbs, and young shoots. Habitat loss due to agricultural expansion and hunting pressure have reduced populations significantly. Conservation programs in Paraguay aim to protect the native grassland ecosystems this deer depends on for its survival.
Brocket Deer
In Paraguay, brocket deer are found across the Atlantic Forest remnants of the east and the vast Chaco region to the west. The gray brocket is especially well adapted to the dry forests and scrublands of the Chaco, while the red brocket favors the more humid eastern forests. Deforestation in Paraguay has been among the fastest in the world in recent decades, making habitat preservation a critical concern for the survival of these deer over the long term.
Jaguarundi
In Paraguay, the jaguarundi occupies the forests and shrublands of the Eastern Region as well as the dry Chaco to the west. It is a secretive animal despite being active during the day, and sightings are relatively uncommon. The IUCN considers it Least Concern, but in Paraguay the Atlantic Forest, once its prime habitat in the east, has been reduced to small fragments, making conservation of remaining forest patches critical.
Margay
In Paraguay, the margay is found mainly in the Atlantic Forest fragments of the eastern region, one of the most threatened ecosystems in South America. Much of this forest has been cleared for agriculture, leaving the margay confined to scattered patches. It is a shy, tree-dwelling cat that hunts at night, rarely detected without camera traps. Protecting what remains of Paraguay's eastern forests is essential for this species. The IUCN lists it as Near Threatened.
Iguana
The green iguana reaches the southern limit of its natural range in Paraguay, found in the warm lowland forests of the eastern Chaco and the Atlantic Forest zone. It inhabits riverbanks along the Paraguay and Paraná rivers, basking in trees above the water. Populations here are less dense than in the tropical zones further north, and the species faces pressure from hunting and ongoing deforestation across the region.
Anaconda
The green anaconda reaches the southern limits of its range in Paraguay, where it is found in the humid Chaco and the wetlands of the northeastern part of the country. The Pantanal ecosystem extends into Paraguay and provides suitable habitat of flooded grasslands and gallery forests. Anacondas in Paraguay are less frequently encountered than in more northern parts of the range and face pressure from habitat conversion for agriculture.
Caiman
Paraguay's yacare caiman populations are among the most notable in the continent, particularly in the wetlands of the Paraguayan Chaco and the country's portion of the Pantanal. These reptiles inhabit rivers, marshes, and seasonal lagoons throughout the lowlands. Regulated hunting programs introduced in the 1990s helped stabilize populations after decades of overexploitation. Caimans continue to serve as important regulators of aquatic food webs across Paraguayan wetlands.
Rattlesnake
Paraguay is home to Crotalus durissus, which thrives in the dry thorn forests and open grasslands of the Gran Chaco region in the west. The Chaco covers more than half of the country and provides ideal conditions for this ambush predator. Paraguayan ranching communities encounter them regularly, and fear-driven killing is common. Conservation efforts focus on educating rural populations about the snake's ecological value as a predator that helps keep rodent numbers in check. IUCN status: Least Concern.
Yellow Anaconda
The yellow anaconda is one of the most iconic reptiles in Paraguay, closely tied to the wetlands of the Chaco and the Pantanal region near the eastern border. It lives in slow moving rivers, marshes and flooded grasslands, where it ambushes fish, birds and small mammals. Despite its size, it avoids humans and plays a key role in the balance of wetland ecosystems.
Lancehead
In Paraguay, lanceheads are most commonly encountered in the humid forests of the eastern region, particularly in the Alto Paraná Atlantic Forest, one of the most threatened ecosystems in South America. Bothrops alternatus, known locally as the urutu, is among the species present. Agricultural expansion has reduced forest cover but lanceheads persist in remaining patches and forest edges, where they continue to control rodent populations.
Boa Constrictor
In Paraguay, the boa constrictor is found mainly in the humid forests of the eastern region and in the dry Chaco woodlands to the west. It is one of the largest snakes recorded in the country. Listed as Least Concern by the IUCN, it faces serious pressure from the dramatic rate of forest loss in Paraguay, particularly in the Chaco, which has seen some of the highest deforestation rates in South America in recent decades.
Barn Owl
The barn owl is found across Paraguay in open farmland, grassland, and the outskirts of towns and villages throughout the country, from the humid eastern region to the dry Chaco in the west. It nests in old buildings, hollow trees, and cliff faces, and hunts rodents at night. In the agricultural communities of eastern Paraguay, where soy and cattle farming dominate, it plays a useful role in controlling the small mammal populations that damage crops and stored grain. It is one of the more commonly encountered owls in the country.
Peregrine Falcon
The peregrine falcon visits Paraguay as a non-breeding migrant, arriving from North American breeding grounds during the austral summer. It travels through the country's open grasslands and along river systems such as the Paraguay and Paraná rivers. Though not a resident breeder here, it is a reliable seasonal presence, hunting small birds across the Chaco and eastern forested regions. Its IUCN status is Least Concern.
Hornero
In Paraguay, the rufous hornero is a common presence in the grasslands and open woodlands of the Chaco and the eastern region. It forages on the ground near farms and villages, picking invertebrates from the soil. Its sturdy mud nest is a familiar sight on fence posts and low branches throughout the country. Populations are stable and the species faces no significant threats. Its IUCN status is Least Concern.
Monk Parakeet
Paraguay is part of the Monk Parakeet's core native range. The bird is widespread across the country's open woodlands, grasslands, and agricultural zones, especially in the Chaco and Eastern Region. It nests communally in trees and on man-made structures, with colonies that can hold dozens of birds. Its loud calls make it one of the most noticeable birds in the Paraguayan countryside. IUCN Status: Least Concern.
Rhea
The greater rhea is the largest bird native to South America, reaching up to 1.5 metres in height. In Paraguay, it lives across the grasslands and dry forests of the Chaco and the eastern region. It shares much of its range with livestock farms. A male courts several females, then incubates all their eggs in a single ground nest and raises the chicks on his own. Its IUCN status is Near Threatened.
Southern Lapwing
The southern lapwing is abundant throughout Paraguay, present in the grasslands and wetlands of the Chaco as well as the agricultural regions of the eastern part of the country. Known locally as the tero-tero, it is a familiar sound on Paraguayan farms and roadsides. It nests on bare ground and defends its territory loudly and fearlessly. Its IUCN status is Least Concern.
Toucan
In Paraguay, toucans are found mainly in the forested regions of the east, particularly in the Upper Paraná Atlantic Forest, one of the most threatened ecosystems in South America. The toco toucan is the species most often spotted here, moving through the remaining forest patches and wooded areas near rivers. Ongoing deforestation in eastern Paraguay has reduced their habitat significantly, making forest conservation efforts essential for their continued presence. IUCN status: Least Concern.
Bellbird
Paraguay's eastern region holds the westernmost populations of this species, within the country's remaining Atlantic Forest. Severe habitat loss has left these birds dependent on scattered forest remnants. The male's extraordinary metallic call, among the loudest of any bird on Earth, can carry over a kilometer through the remaining canopy, making it easier to detect than to see in dense vegetation.
Southern Caracara
The southern caracara is one of the most visible raptors in Paraguay, found across the Chaco in the west and the grasslands and wetlands of the east. Locally called carancho, it is a fixture of rural life, often seen alongside livestock or gathered at carcasses. The Chaco's dry forests and open plains offer ideal conditions for ground foraging, and the bird is common enough to be a well-known part of the country's everyday wildlife.
Rufous bellied Thrush
In Paraguay, the rufous bellied thrush is found across the eastern region, particularly in the remnant Atlantic Forest patches of the Paraná plateau and along gallery forests in the interior. It moves comfortably between natural woodland and the green spaces of Asunción and other towns. On the ground it searches leaf litter for invertebrates, while in fruiting trees it feeds alongside other species of thrush.
