Every year, the list of endangered animals in Paraguay continues to grow. Some species are well known, while others are lesser-known, but all wildlife plays a vital role in maintaining ecological balance and healthy ecosystems.
In this article, we’ll explore 34 species in danger of extinction in Paraguay, spanning mammals, birds, reptiles, amphibians, and invertebrates. We’ll also explain how you can help preserve Paraguay’s biodiversity.
Main Endangered Animals in Paraguay
1. Pampas Deer (Ozotoceros bezoarticus)
The population of Pampas deer in Paraguay has declined by more than 80% over the past century. The species is threatened by:
Illegal hunting
Habitat loss, especially conversion to agricultural land
Disease outbreaks, such as foot-and-mouth disease spread by livestock
Small populations survive in Paso Bravo and San Luis National Parks in northern Concepción.
2. Guanaco (Lama guanicoe)
The guanaco is the only wild camelid native to Paraguay. It is estimated that only around 100 individuals remain, isolated from other South American populations by over 1,000 km. It has been hunted for its meat and fur, and now survives mainly in Médanos del Chaco National Park.
3. Hyacinth Macaw (Anodorhynchus hyacinthinus)
Also known as the blue macaw or arara azul, this is the world’s largest parrot species. It is critically endangered due to:
Poaching for the illegal pet trade
Habitat destruction
In Paraguay, it is found only in the departments of Alto Paraguay and Concepción.
4. Jaguar (Panthera onca)
The jaguar, or yaguareté, currently occupies only 10% of its historical range in Paraguay. Fewer than 500 individuals are believed to remain. Threats include:
Illegal hunting
Loss of natural habitat
Conflict with domestic livestock
5. Giant Anteater (Myrmecophaga tridactyla)
Known locally as jurumí, the giant anteater population in Paraguay has declined by about 30%, with ongoing threats such as:
Wildfires
Road accidents
Agricultural expansion
Now found primarily in the Chaco region: Alto Paraguay, Presidente Hayes, and Boquerón.
6. Lowland Tapir (Tapirus terrestris)
The tapir, or mboreví, has suffered a population decline of 90% or more. Though occasional sightings are reported, they are increasingly rare. Major threats include:
Poaching
Urban encroachment
Habitat fragmentation
This species is associated with diverse forest types and is still found in San Luis, Paso Bravo, San Rafael, and Cerro Corá National Parks.

How to Help Save Endangered Animals in Paraguay
Want to make a difference? Here are conservation strategies you can support or apply:
1. Prevent Deforestation
Enforce sustainable forestry laws and prohibit illegal logging, especially in sensitive ecosystems.
2. Ban Illegal Hunting
Only allow regulated hunting under conservation programs and ensure enforcement by environmental authorities.
3. Stop Wildlife Trafficking
Support legislation and education to stop the illegal pet trade. [Learn how to stop illegal animal trafficking →]
4. Reduce Pollution
Protect water bodies, soil, and air from agricultural and industrial contamination.
5. Support Captive Breeding Programs
Encourage zoos and sanctuaries to breed and reintroduce endangered species into the wild.
6. Restore Forests and Wetlands
Invest in ecological restoration projects to rebuild natural habitats.
7. Limit Urban Expansion
Implement land-use planning to protect critical wildlife corridors.
8. Create More Protected Areas
Expand national parks and reserves to ensure more species have safe zones to survive.
9. Volunteer or Donate
Support organizations like WWF, SeoBirdLife, or local groups. You can also volunteer in Paraguay’s national parks and nature reserves.
Final Thoughts
The loss of biodiversity in Paraguay is a serious concern—but not a hopeless one. Understanding the threats, raising awareness, and taking action are the keys to preventing extinction.
