Red Collared Lemur

Eulemur collaris

male-collared-brown-lemur-faceThe adult Collared Lemur can be about the size of a large house cat, weighing about 5.7 lbs (2.6kg) with a body length of 16 inches (41cm), with a tail as long as 22 inches (55cm). It can live 20-25 years.

Males are brownish-gray with a dark stripe down the back, a dark tail and tail tip, and a lighter underside. Females have a reddish to brown coat and a gray face. Both sexes have a distinct beard that is reddish-brown in females and cream to reddish-brown in males. Collared lemurs are distinguished from the very similar white-collared lemurs by a slightly darker beard.

Feeding

Collared Lemurs have a diet mostly consisting of fruit, young leaves, and flowers. Due to their generalist feeding patterns and their social system consisting of multiple adult males and females, groups of brown lemurs are easily maintained in captivity and thrive on just a basic diet of monkey chow and fruit. Around 60% of their diet consists of fruit and they are active both day and night, mostly at dawn and dusk; however little is known about the feeding ecology of collared lemurs.

Reproduction

female-collared-brown-lemur-and-collared-brown-lemur-male-infantCollared lemurs are seasonal breeders, with mating season occurring between June-July. Gestation last approximately 120 days, and infants are born between September and November. One offspring a year is typical. Collared lemurs reach sexual maturity at about 1 year old.

Social Behavior

Collared lemurs are sociable, living in permanent groups of 3 – 12 individuals. Groups as large as 29 have been observed.  Unlike many species of lemur which are female dominant, there does not appear to be a clear dominance hierarchy within groups. Groups of brown lemurs are very cohesive, and stay closely together as they move through the forest feeding on leaves and fruit. The animals are usually found high in the canopy and they rarely descend to the ground. There may be a significant overlap (up to 20%) of the ranges of neighboring groups, which occasionally leads to hostile (but not violent) territorial encounters. Home range boundaries are probably maintained by vocalizations. Their home range tends to span 17 – 50 acres (7 – 20 ha), usually in the scattered forest fragments of the high plateaus in southeastern Madagascar, from the Mananara River near Vangaindrano south to Fort-Dauphin.

Habitat & Conservation

The collared lemur is found in lowland and mid altitude primary and secondary rainforest in a small range in the southeastern tip of Madagascar. This lemur ranges from the Mananara river south to the area north of Tolagnaro. The western limits of its range have yet to be firmly established, and on the north it borders populations of Eulemur fulvus albocollaris with which it might interbreed.

It occurs in only one protected area. The DLC maintains 3 males and 3 females, none of whom are breeding.
