White-collared brown lemur  (Eulemur albocollaris)

This medium-sized lemur has a horizontal posture, which is suited to its predominantly quadrupedal mode of movement (2). These lemurs are also capable of leaping considerable distances, their long furry tails assisting them in maintaining their balance (5). Although very similar in appearance to the collared brown lemur or red-collared lemur (Eulemur collaris), genetic analysis supports distinct species status (6). Males possess grey-brown upperparts, with darker lower limbs and tail, paler grey underparts, grey head and face and a darker crown. Females have redder-brown upperparts, paler underparts and darker feet than males. The cheeks and beard are white, bushy and pronounced in males, but reddish-brown and less bushy in females. The white-collared brown lemur earns its common name for the white cheeks of the male, which differ from the cream to brownish-orange cheeks of the collared brown lemur (2).
