A few observations suggested that there may sometimes be two adult females with a male. Strangers of the same sex generally were hostile. Contact between members of a group was maintained by soft whistles. Litters contain two to six young. They are suckled for 15 weeks and then begin to forage with the parents.
Regurgitation is evidently rare.
The young are probably full grown by 5 or 6 months and separate from the parents prior to the breeding season.
