Some groups of mongoose lemurs will switch from diurnal activity (active during the day) to nocturnal activity (active at night) at the beginning of the dry season
At the Zoo
There are two mongoose lemurs at Brookfield Zoo:

Status in the Wild
Mongoose lemurs are sexually dimorphic (have two distinct gender forms). Females have a gray head, forelimbs, and shoulders, with a dark back and a white beard; males are generally darker with a reddish-brown beard. They are about the size of a small domestic cat.
Mongoose lemurs are found in only one protected area in Madagascar, which is currently being cleared for pasture, charcoal production, and cropland. Mongoose lemur habitat is also disappearing rapidly in the Comoros Islands. Although this species is protected under Malagasy law, it is hunted extensively for food and the pet trade.
