Brown lemurs are medium-sized with dense, soft coats that vary in color from gray-brown to reddish-brown, depending on the species and region. All lemurs live in Madagascar, but each individual species lives in a different region within the island. They typically have a dark face mask surrounded by lighter fur, expressive amber or orange eyes, and a long bushy tail that aids in balance. Males and females look quite similar, which makes them somewhat unique among lemur species where physical differences between sexes is common. These animals are very social and live in groups of up to 12 individuals. They are known for their vocal communication, which includes grunts, clicks, and alarm calls. Brown lemurs are diurnal, meaning they are active during the day, and they spend much of their time foraging for fruit, leaves, flowers, and occasionally insects. Breeding usually occurs during the dry season, with females giving birth to a single infant after a gestation period of about four months. The young are carried by their mothers and become more independent after a few months, though they stay close to the group for protection and social learning.
