ACTIVITY PATTERN OF THE BROWN HOWLER MONKEY ALOUATTA-FUSCA, GEOFFROY 1812, IN A FOREST FRAGMENT OF SOUTHEASTERN BRAZIL

A group of six brown howlers was studied during a year in the Santa Ge nebra Reserve, a 250ha-forest fragment near the city of Campinas, Stat e of Sao Paulo, southeastern Brasil. On average, the group rested for 64% of the daylight hours and feeding and moving occupied 18% and 13% of this period, respectively. A greater proportion of time was spent f eeding during dry season (24%) than the wet season (15%), and the reve rse observed for time spent resting (59% and 69% of the group's daylig ht hours during dry and wet seasons, respectively). The increase of re sting and decrease of feeding during wet season were related to the pe rcentage of leaves in the group's diet, high even during the fruiting season (wet season). However, additional data of other groups are nece ssary to draw conclusions about the effects of habitat disturbance on this population.
