Reproduction
A young diademed sifaka and his mother. Click image for larger version.
A female will give birth to a single offspring which initially will cling to her belly, but which gradually transfers to her back. At the age of two to three months, the infants may begin to venture off on short independent forays away from the mother. Infants off by themselves as well as independent juveniles might fall prey to a ground predator, the fosa (Cryptoprocta ferox) or to large raptors such as the Madagascar Harrier Hawk (Polyboroides radiatus). Like many lemurs, the diademed sifaka has different vocalizations for ground and aerial predators.
