Food Habits of Formosan Rock Macaques (Macaca cyclopis) in Jentse, Northeastern Taiwan, Assessed by Fecal Analysis and Behavioral Observation



We studied the food habits of the Formosan rock macaques (Macaca cyclopis) in Jentse via fecal analysis and direct field observation from October 1991 to September 1992, and recorded macaques eating 51 plant species and insects of ≥5 orders. Macaques in Jentse spent more time feeding on fruits than on other plant parts or insects. However, there was seasonal variation in their food habits, i.e., they spent a higher proportion of time feeding on fruits and insects in summer, and on leaves and stems in winter. The major plant species consumed and the patterns of seasonal variation in the macaque diets identified by fecal analysis and field observation are similar. However, there are discrepancies between results from the two methods in some of the finer details of estimated dietary composition.
