Collared Lemur (Eulemur collaris) Fact Sheet, 2015
Species: E. collaris - Collared lemur
Measurements taken from 28 adults:
Body Weight: 1861-2150 g (4.1-4.7 lb)
Head & Body Length: 45.4-46.1 cm (c. 18 in)
Tail Length: 50.1-50.3 cm (c. 19.7 in)
Pelage: Brown coat with a "collar," or ruff of hair, framing the cheeks and extending to the ears. Male coats are brownish-gray, slightly lighter than females, with a reddish-orange or creamy collar. Females have darker body hair and less developed collars. Tails are dark reddish-brown.
|Distribution & Status||Behavior & Ecology|
Range: Limited to a small region in Southeastern Madagascar
Habitat: Littoral, tropical lowland and montane forests
IUCN Status: Endangered A2cd+3cd_4cd, version 3.1
CITES: Appendix I
Population in Wild: No published estimates; threatened by habitat loss, hunting and trapping
Locomotion: Arboreal quadrupeds, primarily leaping
Activity Cycle: Cathemeral year-round; some seasonal variations in activity patterns
Social Groups: Live in multi-male, multi-female groups; no apparent dominance hierarchy
Diet: Diverse diet of over 120 plant species. Primarily consumes ripe fruit; also eats flowers and leaves. Occasionally eats invertebrates.
Predators: Fossa (Cryptoprocta ferox), diurnal raptors and humans
|Reproduction & Development||Species Highlights|
Sexual Maturity: c. 3 years, in captivity
Gestation: c. 120-128 days, in captivity
Litter Size: 1-2; a single offspring is most common
Birth Weight: 60-90 g (2-3 oz)
Age at Weaning: Begins at 3-4 months, proceeds gradually
Longevity: Typical lifespan in the wild not known. In captivity, life expectancy is c. 22 years. Maximum longevity of c. 32 years reached by a male and female in North American zoological institutions.
Feature Facts: Also known as the red-collared or red-collared brown lemur, the collared lemur was previously considered a brown lemur (E. fulvus) subspecies. Primarily arboreal and sociable, it lives in multi-male, multi-female groups of 2-17 individuals without a clear dominance hierarchy. It is a relatively large lemur, similar in size to the ring-tailed lemur.
The species has undergone a population decline of ≥50% over a period of 24 years, which is expected to continue.
