When most people picture bears, grizzlies or pandas likely come to mind, but deep in the cloud forests and highlands of the Andes, a shaggier, lesser-known cousin quietly roams: the spectacled bear, also known as the Andean bear. This bear is found in western South America, including countries like Venezuela, Colombia, Ecuador, Peru, and Bolivia. As the only bear species native to South America, it ranges from western Venezuela to Bolivia, with Peru hosting some of its most vital remaining habitats. Recognizable by the pale, often mask-like markings around its eyes—unique to each individual—this elusive species plays a crucial ecological role in its mountainous environment. Despite its importance, the spectacled bear is one of the least understood bears in the world and faces growing threats from habitat fragmentation, agriculture, and human-wildlife conflict. Learning about these fascinating creatures is not just a window into South America’s unique biodiversity—it’s also a reminder of the urgent need to protect what’s left of their disappearing ecosystems.
1. The Spectacled Bear Is the Only Bear in South America
Of the world’s eight bear species, only one made it to South America: the spectacled bear (Tremarctos ornatus). Also called the Andean bear, it’s a relict species of a once-diverse bear lineage that dates back to prehistoric times. The spectacled bear is a mid-sized animal with short but strong legs and fur that ranges from jet black to dark brown and even a reddish hue, showcasing significant variability in color among individual bears.

3. Spectacled Bears Are Mostly Herbivores
Despite being bears (and having massive canine teeth), they’re surprisingly gentle eaters. About 90% of their diet is plant-based, including fruits, bromeliads, palm hearts, cactus, and orchid bulbs. Natural food sources are crucial for their diet, and habitat loss can lead to shortages, driving them to raid crops or intrude into human settlements. Much of this plant-based diet is gathered from the forest floor, where fallen fruit is a common food source. Compared to other bears, spectacled bears are predominantly herbivorous, consuming a diet low in meat. However, they won’t turn down the occasional rodent or bird egg if the opportunity arises.

4. They Live in the Andes—But Also in Dry Forests
While most people associate the spectacled bear with the cloud forests of the Andes, they’ve also been spotted in dry forests like those of northwestern Peru. Spectacled bears face challenges in the northern Andes due to the insufficient size of protected areas. However, the very humid montane forests, thriving at elevations between 500 and 2,700 meters, are crucial habitats for these bears within their geographical range. These forests provide abundant food sources and diverse ecosystems that support the species. In fact, these lesser-known habitats may be some of their last safe havens. Bears often descend to lower altitudes during the fruiting season (December–March), especially to snack on sapote fruits.

5. They’re Vital Seed Dispersers
These Peruvian bears aren’t just cute, they’re ecologically essential. As they munch on fruit and wander long distances, they excrete seeds far from where they ate. This helps regenerate forests and maintain plant diversity. In conservation terms, they’re considered an umbrella species, meaning protecting them helps conserve many other species that share their habitat.
