Geographic range: These sifakas live on the southeastern coast of Madagascar.

Milne-edwards’s sifaka habitat: Milne-Edwards’s sifaka is found in moist, humid mountain rainforests.

What does milne-edwards’s sifaka eat: Milne-Edwards’s sifaka eats fruits, fruit seeds, leaves, and flowers.

Behavior and reproduction: The Milne-Edwards’s sifaka is diurnal, or active during daylight hours. It travels by leaping and clinging onto trees. It usually feeds within large trees, but may food search on the ground. On the ground, sifakas hop on their hind legs in an upright position, holding arms above their heads for balance. At night they sleep with a social group high in the trees. Sleeping locations can change each night to avoid predators.

Social groups have up to ten members. These groups may be all male, all female, or mixed. Females are dominant, leading their group and demanding first choice of food. However, males defend the group against large raptors, such as hawks and eagles.

Sifakas are mature at four to five years old. Females may mate with several males. One infant is born every two years. Newborns weigh 4.4 ounces (125 grams). They cling to the mother’s underside for their first month, then ride on her back for the next four months. Infant mortality, or death rate, is high.

Milne-Edwards’s sifakas have several vocalizations, or sounds. The loud alarm barking sound warning about bird predators may last up to fifteen minutes. A short, quick “zusss” call warns of ground predators, or enemies. Quiet “moos” tell of a group’s current location. Lost sifakas give a long, warbling whistle to announce where they are.

Milne-Edwards’s sifakas and people: In some areas, it is forbidden by local custom to hunt sifakas because they resemble humans.

Conservation status: Though not listed as Threatened, MilneEdwards’s sifakas may become threatened due to hunting, logging, firewood use, land clearing to provide pasture for livestock, and slashand-burn agriculture. It has so far been impossible to keep and breed this sifaka in captivity.
