Andean arboreal bear
Spectacled bears climb extensively to reach fruit, bromeliads, and cactus pads. They build platform nests in trees for resting and feeding. Their short, broad muzzle and strong jaws crush tough vegetation unavailable to many other Andean mammals.
Facial markings
Each bear's pale spectacled pattern is unique — rings, semicircles, or light muzzles vary individually. The markings may aid recognition between bears in dense forest. Despite the name, not every individual has obvious 'glasses'.
Shy temperament
Spectacled bears are generally shy and diurnal, avoiding people when possible. They are not aggressive hunters; small mammals and carrion supplement a mostly vegetarian diet. Males may have large home ranges overlapping several females.
Conservation in the Andes
Listed Vulnerable, spectacled bears lose habitat to cattle grazing, crop expansion, and mining roads that fragment cloud forest. Corridors linking protected areas in Peru, Ecuador, and Colombia are priorities. The species is culturally significant as the 'Andean bear'.

Conservation status of the Spectacled Bear
The spectacled bear (Tremarctos ornatus) is listed as Vulnerable on the IUCN Red List. Vulnerable (VU) means a species faces a high risk of extinction in the medium-term future. It is the lowest-risk of the three 'threatened' IUCN categories — one step below Endangered, which is itself below Critically Endangered — and is often an early warning that a population is in trouble.
