Episode Summary
Executive Summary: Science Friday spotlights the Tilcayo, a tiny Bolivian wild cat recently described as a new species after decades of confusion with other tiger cats. Biologist Paolo Nogales-Escaloon recounts the cat’s accidental discovery, the slow genetic and museum-based verification process, and how the species’ viral popularity is now boosting pride, conservation interest, and attention to Bolivia’s threatened Jungas Forest.
Main Topics: Discovery of the Tilcayo (Priority: 5/5): A rural resident in Bolivia found a kitten in the Jungas Forest, raised it, and later realized it was wild after unusual behavior like chasing chickens led to a rescue center. Scientific identification and skepticism (Priority: 5/5): Nogales-Escaloon explains that the cat was long assumed to be Leopardus tigrinus, and multiple genetic tests initially seemed inconclusive, reinforcing the caution scientists use before claiming a new species. Museum research and taxonomic confirmation (Priority: 4/5): After the genetics pointed to something new, the team checked museum specimens and historical descriptions to ensure the cat had never been formally described before. Public reaction and cultural buzz in Bolivia (Priority: 5/5): The cat has become a national sensation, appearing on social media, in public transport conversations, and even inspiring street art and political attention. Conservation potential for small cats and forests (Priority: 5/5): The Tilcayo may become a flagship species that draws attention to the Jungas Forest, helping protect habitat threatened by deforestation and mining. Funding challenges for small-cat conservation (Priority: 4/5): Nogales-Escaloon notes that conservation funding overwhelmingly favors jaguars, while small cats are harder to study and rarely receive dedicated support. Personal motivation and career reality (Priority: 3/5): Despite leading cat research, he says he pays the bills with crop genetics and works on wild cats largely out of passion, hoping the discovery may open new funding opportunities.
Key Arguments: The Tilcayo is likely the first new wild cat species described in over a century, but proving that required years of genetic work and historical comparison. Initial test results were not immediately trusted; scientific skepticism delayed publication because researchers assumed they had made an error. Museum collections and old naturalist records were necessary to rule out prior descriptions and confirm the cat was truly undescribed. The species’ popularity can help conservation by making the Jungas Forest more visible and valuable to the public and decision-makers. Small cats are underfunded and difficult to study because they are secretive and rarely observed, unlike larger charismatic wildlife. The speaker hopes the cat’s fame will attract grants or an NGO-style funding stream so he can focus full-time on cat conservation.
Data Points: Time to describe species: nearly 10 years - Paolo Nogales-Escaloon worked for almost a decade to formally describe the Tilcayo. Species discovery gap: more than 100 years - The Tilcayo is presented as the first new wild cat species described in over a century. Cat weight: 3 pounds - The opening describes the Tilcayo as an itty-bitty three-pound spotted cat. First seen by scientist: 2017 - Nogales-Escaloon says he first met the cat in a rescue enclosure in 2017. Initial failed genetic tests: 2 attempts - He describes first trying saliva and then hair before later returning with better training. Local habitat: Jungas Forest - The cat was found in a rural area of the Jungas Forest in Bolivia. Research focus: jaguars, ocelots, margays - His program studies wildcats including these larger species alongside smaller cats.
Pivotal Quotes: "The cat is everywhere." — Flora Litchman: Describing the virality and celebrity status of the Tilcayo on social media. "I was like, Of course, the picture is like the book is so wrong. Like, what happened with these people?" — Paolo Nogales-Escaloon: Explaining the moment he realized the published cat description did not match the animal he was studying. "To pay the bills, I don't do cats. I work with crops and I do Kinoa and I do kanyawa, you know, like genetics of those to pay the bills." — Paolo Nogales-Escaloon: Showing the funding reality that forces him to support his conservation passion through crop genetics work.
Implications: The Tilcayo’s fame could redirect attention and funding toward small cats and the Jungas Forest, turning a viral discovery into real conservation gains for overlooked ecosystems and species.
