Their area is quite small, consisting only of the north coast of the Cap d' Ambre peninsula. Their meals cosist of various fruits, young leaves, flowers, pollen from those flowers and are occasionally known to eat some small insects. The normal group size tends to be from 5 to 6 lemurs, although groups of 16 have been located in the wild. During the day subgroups can be found feeding, with members from 1 to 4 strong. Similar to other lemurs, contact through vocalization is commonly used among the Crowned lemur species.
Female dominance is present, and bondage through grooming is also shown.
Although the norm is one offspring, the odds of twins are practically equal. At the age of 20 months most females are ready to begin producing offspring. They mate seasonally around May to June, and give birth around September to October, which is a gestation period of 125 days. Five to Six months after the young are born, they are completely weened from their mothers. The major threats of the Crowned lemurs are poaching, brush fires, and logging.
