Groups and Breeding.

After mating the gestation period for this species is around 150 days. A family group can have a territory range of around 74 acres.
Even though it has been extensively collected for the pet trade its numbers remain very steady and since its introduction to a new range it has flourished so much in inner city areas such as Rio De Janeiro that it is in places considered a pest.
