MILESTONE FOR SCIENCE IN BOLIVIA

Clouded tiger cat: Why scientists are amazed by the presence of this species in Cochabamba?

The night of February 8, 2025 marked a new milestone for science in Bolivia. Around 8:30 p.m., biologist Oliver Quinteros Muñoz, together with other herpetologist researchers, was conducting amphibian and reptile monitoring in the Sehuencas area, inside Carrasco National Park, about 160 kilometers from the city of Cochabamba. While surveying a section of secondary Yungas forest or montane forest, at 2,251 meters above sea level, their flashlight unexpectedly illuminated a feline resting on the branch of a mountain alder tree (Alnus acuminata), only 1.30 meters above the ground.

“The most surprising thing was that the animal appeared docile and remained calm for about eight minutes,” Quinteros-Muñoz told La Región. This passiveness allowed the biologists to approach within two meters and capture high-quality photos and videos using a mobile phone. They were also able to clearly observe the pattern of dark, irregular rosettes and other physical traits. There was no doubt: it was a clouded tiger cat, or Andean oncilla [watch video]; recently elevated to full species status, since until before 2024 it had been considered a subspecies of the tiger cat (L. tigrinus pardinoides).

From chance encounter to scientific paper

The sighting went from being a field anecdote to becoming a scientific milestone once the researchers realized it represented the first formal record for the department of Cochabamba and for Carrasco National Park. After consulting with other experts such as mammalogist Damián Rumiz, Quinteros-Muñoz and the other researchers decided to write a scientific paper presenting the results of their investigation.

Finding the clouded tiger cat in this part of Bolivia helps close an information gap that existed between La Paz and Tarija: 760 kilometers in a straight line between one point and the other. “The first record of Leopardus pardinoides (=L. tigrinus) in Bolivia dates back to 2001, in Apolobamba. In 2017 and 2022 it was recorded in Cotapata (both in northern La Paz). Later, Ximena Vélez-Liendo (an expert in large mammals) provided us with information about a record in Tarija,” says Quinteros-Muñoz.

With the discovery at an intermediate point (Cochabamba), it is now possible to continue studies on the species’ distribution range and to highlight the importance of ecological corridors, or forest connectivity, in this case montane forests or Yungas ecosystems.

“Green corridors or biological corridors allow wildlife to move and distribute continuously from northern La Paz to the south of the country,” says Quinteros-Muñoz.

A discovery at a crucial moment

The study, published in the journal Notas sobre Mamíferos Sudamericanos, identifies the specimen observed in Carrasco National Park by its physical characteristics that distinguish it from other species: a size similar to a domestic cat, short rounded ears, and a pattern of irregular solid-black rosettes over a yellowish-brown background.

From the standpoint of wildlife classification, this record comes at an important time because the Andean oncilla was only recently recognized as an independent species; a classification that is still in the process of being updated in international threat lists such as those of the International Union for Conservation of Nature.

Above all, however, it is a conservation milestone, because it is now known that this small wild cat inhabits a national protected area, which enhances the value of that designation. “In terms of research, it matters because it shows that there is still much left to discover in Carrasco National Park,” concludes Quinteros-Muñoz.
