Males have a white or cream colored head, ears and beard.
Infants cling to their mothers' bellies for the first 3 weeks, shifting only to nurse. At approximately 3 weeks of age, the young lemurs will begin spending time riding, jockey style, on mom's back, and then will take their first tentative steps. With this hint of independence, infants begin to taste solid food, sampling bits of whatever the other members of their group are eating. Nursing continues, in a steady decline in importance in the infant's diet, until the infant is weaned at approximately 5 - 6 months of age. Social groups will often break into subgroups throughout the day and come back together at night Unlike many prosimians, brown lemurs do not show marked female dominance.
