The spectacled bear and the brown bear are both members of the bear family, Ursidae — but they sit on very different branches of the tree, live on different continents, and eat very different diets. Here is how they really compare.
Different branches of the bear family
The brown bear (Ursus arctos) belongs to the subfamily Ursinae, the group that contains most living bears. The spectacled bear (Tremarctos ornatus) is the last surviving member of the Tremarctinae, or short-faced bears — a separate lineage. So while both are true bears, they are only distant cousins. For the full profile of the Andean species, see our spectacled bear species guide.
Where they live
The brown bear is one of the most widespread bears on the planet, ranging across North America, Europe and Asia, and includes the grizzly. The spectacled bear lives only in the Andes of South America — from Venezuela to Bolivia — mostly in cloud forest around 1,000–2,700 metres elevation. It is the only bear native to South America.
Size and build
Brown bears vary enormously by region, with males ranging from roughly 130 kg to well over 600 kg in the largest coastal populations. Spectacled bears are smaller: males weigh about 100–200 kg and females about 35–82 kg. The spectacled bear's short, deep skull also gives it a more compact, rounded face than the longer-muzzled brown bear.
Diet
Both are technically carnivorans, but their diets diverge sharply. Brown bears are true omnivores and take significant animal protein — salmon, mammals, carrion and insects, depending on region. The spectacled bear is overwhelmingly herbivorous, with roughly 90–95% of its diet made up of bromeliads, palm hearts, fruit, bark and orchid bulbs.
Conservation status
Globally the brown bear is listed as Least Concern by the IUCN, thanks to its large and widespread populations. The spectacled bear is listed as Vulnerable, with a decreasing trend and a projected decline of more than 30% over three generations as Andean cloud forest is cleared and fragmented.
Quick comparison
- Family branch: short-faced (spectacled) vs typical bears (brown)
- Range: Andes only vs three continents
- Male weight: ~100–200 kg vs ~130–600+ kg
- Diet: ~90–95% plants vs broadly omnivorous
- IUCN status: Vulnerable vs Least Concern
Because the spectacled bear has such a small, fragmented range, protecting connected cloud forest matters far more for its survival than it does for the wide-ranging brown bear. Network-funded partners work on exactly that; you can quietly support habitat protection if it speaks to you.
