Habitat and range

Where each species lives and the conditions it tolerates.

Habitat types Differs

Sunda Clouded Leopard

tropical rainforest, montane forest

  • Tropical rainforest
  • Montane forest

Lowland and hill dipterocarp forest, peat swamp forest and montane forest; the species also uses selectively logged forest, though at lower densities than in primary habitat.

Clouded Leopard

tropical rainforest, montane forest, dry forest

  • Tropical rainforest
  • Montane forest
  • Dry forest

Primarily closed-canopy evergreen forest, but also recorded in secondary growth, mangrove, dry woodland and, in the Himalaya, forest above 8,000 feet.

Geographic range Same

Sunda Clouded Leopard

Asia

  • Asia

Endemic to Borneo and Sumatra, with separate subspecies recognised on each island.

Clouded Leopard

Asia

  • Asia

Mainland South East Asia and the eastern Himalaya: Nepal, north-east India, Bhutan, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia and southern China.

Diet and behaviour

Feeding ecology, social organisation and hunting technique.

Main prey Differs

Sunda Clouded Leopard

small mammals, primates, birds, medium ungulates

  • Small mammals
  • Primates
  • Birds
  • Medium ungulates

Bearded pig, mouse deer, macaques, proboscis monkeys, porcupines, civets and birds.

Clouded Leopard

primates, small mammals, birds, medium ungulates

  • Primates
  • Small mammals
  • Birds
  • Medium ungulates

Gibbons, macaques, slow lorises, porcupines, squirrels, pheasants, small deer and pigs, taken both in trees and on the ground.

Social structure Same

Sunda Clouded Leopard

Solitary

Individuals maintain large home ranges relative to body size; detections are strongly associated with continuous forest cover.

Clouded Leopard

Solitary

Secretive and rarely observed directly; most ecological knowledge comes from camera trapping and a small number of radio-collared animals.

Activity period Same

Sunda Clouded Leopard

Nocturnal and crepuscular

Camera-trap data show a strong night-time peak, with some crepuscular movement.

Clouded Leopard

Nocturnal and crepuscular

Camera-trap records cluster at night and around dusk, with daytime resting in trees.

Hunting strategy Differs

Sunda Clouded Leopard

Stalking ambush in forest

Hunts both from branches and along the ground, taking prey up to the size of a young bearded pig.

Clouded Leopard

Arboreal and ground ambush

Prey is approached quietly and killed with a bite to the nape or skull, aided by unusually long canines.

Climbing ability Same

Sunda Clouded Leopard

Exceptional

Highly arboreal, with the same rotating ankle anatomy as the mainland species.

Clouded Leopard

Exceptional

One of the most arboreal cats: it can hang from branches by its hind feet and climb down trunks head first.

Swimming ability Same

Sunda Clouded Leopard

Capable

Recorded crossing rivers within its forest range.

Clouded Leopard

Capable

Recorded crossing rivers, though the species is not associated with wetlands.

Documented threats Differs

Sunda Clouded Leopard

Conversion of forest to plantation, Logging, Fragmentation of lowland forest, Snaring, Trade in skins

  • Conversion of forest to plantation
  • Logging
  • Fragmentation of lowland forest
  • Snaring
  • Trade in skins

Conversion of lowland forest to oil-palm plantation has removed a large share of the best habitat on both islands, leaving increasingly isolated forest blocks.

Clouded Leopard

Deforestation, Indiscriminate snaring, Trade in skins, teeth and bones, Prey depletion, Habitat fragmentation

  • Deforestation
  • Indiscriminate snaring
  • Trade in skins, teeth and bones
  • Prey depletion
  • Habitat fragmentation

Forest loss across South East Asia is the dominant pressure, compounded by intensive snaring that removes both the cat and its prey.

Notable traits

Details that do not fit neatly into a measurement table.

Sunda Clouded Leopard

  • It was described as a distinct species only in 2006, after genetic comparison with mainland clouded leopards.
  • Its cloud markings are smaller, darker-edged and more densely spotted than those of the mainland species.
  • On Borneo it occupies the ecological role that tigers and leopards fill elsewhere in Asia.

Clouded Leopard

  • Relative to skull length, its canines are the longest of any living cat, a proportion often compared with extinct sabre-toothed forms.
  • Rotating hind ankles allow head-first descent, a trait shared with very few other cats.
  • The tail can be as long as the head and body, acting as a balance beam in the canopy.
