White-headed lemur

The white-headed lemur (Eulemur albifrons) is a medium-sized primate of the family Lemuridae that lives only in north-eastern Madagascar. It is arboreal and usually found in the treetops of moist lowland and montane rainforest, where it is cathemeral, active at varying times of day and night. Its diet is omnivorous, taking fruit, mature leaves, flowers, bark, sap, soil and invertebrates, and shifts with the reproductive state of the females. Adults weigh about 2.3 kg, males have gray-brown upper parts with bushy white cheeks, and individuals can live up to 30 years. Once treated as a subspecies of the common brown lemur, it is classified as Vulnerable on the IUCN Red List.
