## Key facts: Spectacled Bear
- Spectacled bears are the sole surviving members of the short-faced bear subfamily (Tremarctinae), a lineage that once included the extinct giant short-faced bear.
- They are found across the Andean mountain chain from Venezuela to Bolivia, primarily in cloud forest, with a typical core band around 1,000–2,700 metres elevation.
- They are the largest land member of the order Carnivora in South America, though their diet is roughly 90–95% plant-based — fruits, bromeliads, palm hearts, and orchid bulbs.
- Adult males use home ranges on the order of ~23–61 km² depending on region and season — making them sensitive to habitat fragmentation, not the 600 km² sometimes claimed.
- They are killed by farmers protecting crops and livestock, though actual predation of livestock by spectacled bears is rare and often over-attributed to them.
- Cubs are sometimes orphaned and seized from the illegal pet trade after their mothers are killed, ending up in confiscation and rescue centres.

## The Cloud Forest Under Pressure
Andean cloud forest — the primary habitat of the spectacled bear — is among the most biodiverse and most threatened ecosystems on earth. In Colombia and Peru, illegal coca cultivation has penetrated previously intact cloud forest, bringing with it road construction, deforestation, and human settlement. Cattle ranching continues to push upslope as lowland pasture becomes degraded. Mining and oil concessions in the Andean foothills displace communities upward, increasing pressure on higher-altitude forest. The spectacled bear needs large, connected territories, so fragmentation of cloud forest into isolated patches is as damaging as outright loss. The IUCN identifies habitat loss and fragmentation as the leading driver of the species' decline.

## Conflict With Farmers
Spectacled bears occasionally raid crops — maize and sugarcane in particular — and are sometimes blamed for livestock losses that may actually be caused by pumas or feral dogs. Retaliatory killing is the most common cause of direct human-bear mortality. Farmers set snares and shoot bears that enter agricultural land, often without distinguishing between genuine and alleged crop raiders. WARN supports conflict-mitigation programmes that combine compensation for verified livestock losses with non-lethal deterrents and community engagement in bear-range communities.

## Spectacled Bears in Myth and Reality
The spectacled bear is the species behind Paddington Bear's Peruvian origins. Author Michael Bond's character actually grew from a toy bear he bought near Paddington Station in 1956; the 'Darkest Peru' backstory and the spectacled-bear association came later, after it was pointed out that there are no bears native to Africa. The bear also holds deep cultural importance in indigenous Andean traditions, appearing in art, ceremony, and cosmology as a forest spirit. Despite this significance, legal protections in range countries are inconsistently enforced and wildlife-crime data are poorly collected. WARN works with local partner organisations that combine community relationship-building with practical conservation work.

## Spectacled bear vs brown bear

| Scientific name | Tremarctos ornatus | Ursus arctos |
| Subfamily | Tremarctinae (short-faced bears) | Ursinae |
| Range | Andes of South America | North America, Europe, Asia |
| Male weight | ~100–200 kg | ~130–600+ kg (varies by region) |
| Diet | ~90–95% plant matter | Omnivorous; more animal protein |
| IUCN status | Vulnerable | Least Concern (globally) |
| Notable trait | Only South American bear; last short-faced bear | Widespread; includes grizzly populations |

## What WARN does
WARN partners with rescue and rehabilitation centres in Colombia and Peru to fund care for confiscated and orphaned bears, and supports conflict-mitigation programmes in farming communities on the edge of bear habitat.

When a mother spectacled bear is shot over a crop dispute, it is often her cub that survives — orphaned, sometimes seized from the illegal pet trade, and unable to fend for itself. Your gift helps WARN fund partner rescue and rehabilitation centres in Colombia and Peru that care for these confiscated and orphaned Andean bears, and the community conflict-mitigation work that prevents the next orphan.

## Frequently asked questions: Spectacled Bear
### Is the spectacled bear the inspiration for Paddington Bear?
The spectacled bear is the species behind Paddington's Peruvian origins, but the character did not begin with a real bear. Michael Bond was inspired by a toy bear he bought near Paddington Station in 1956; the 'Darkest Peru' setting and the spectacled-bear association were chosen later, once it was noted that bears are not native to Africa. Wild spectacled bears are shy and largely solitary, active mostly around dawn and dusk, and rarely encountered by people.

### What does a spectacled bear eat?
Despite being classified within the order Carnivora, spectacled bears are largely herbivorous — roughly 90–95% of their diet is plant material. They eat bromeliads (including the leaf bases and hearts), palm hearts, orchid bulbs, tree bark, and fruit, and occasionally insects, honey, and small animals. Their robust, short-faced skull and strong jaw muscles let them bite through tough fibrous vegetation that other animals cannot access.

### How many spectacled bears are left?
The IUCN estimates roughly 2,500–10,000 mature individuals, with a decreasing population trend; a figure of around 18,000 total animals is widely repeated but is a popular upper estimate rather than the IUCN's mature-individual count. In its 2017 assessment the IUCN lists the species as Vulnerable (criteria A4cd) and projects a reduction of more than 30% over three generations (about 30 years) if current habitat loss continues.

### How big is a spectacled bear?
Adult males weigh roughly 100–200 kg and females about 35–82 kg, standing around 60–90 cm at the shoulder with a head-and-body length of about 1.2–2.0 m. Males can be substantially larger than females, a clear example of sexual dimorphism.

### How long do spectacled bears live?
In the wild they typically live around 20–25 years. They live longer in captivity; the documented record is 36 years 8 months.

### Is the spectacled bear the same as the Andean bear?
Yes. 'Spectacled bear' and 'Andean bear' are two common names for the same species, Tremarctos ornatus. 'Andean bear' is increasingly preferred in conservation literature, while 'spectacled bear' refers to the pale rings that often mark the face.

### Do spectacled bears really attack livestock?
Occasionally, but less frequently than farmers believe. Conflict studies suggest that pumas and feral dogs account for a substantial share of livestock losses in spectacled bear habitat, and losses are often misattributed to bears. That misattribution increases retaliatory killing and makes conflict harder to resolve.
