Equivalent values for Groups I and II were 23 percent and 33 percent. Within each study area, the composition of the animals' diet changed almost completely between sea- sons. Only 5 food species out of a total of 77 eaten in the course of observations were utilized by the south- ern groups for more than 1 percent of total feeding time in both seasons. The northern groups ate 9 out of a total of 99. Species eaten throughout the year tended to be those which produced leaves throughout the year, and animals fed regularly on these leaves at an immature and/or mature stage. Species that dominated the animals' diet for a short period and then disappeared from it were commonly those that produced flowers and fruit with close synchrony be- tween individuals and that shed their leaves during the dry season. food parts eaten. There were marked differences in the overall quantity of various food parts eaten by the groups in each study area. In the north, imma- ture leaves were a primary dietary item whereas in the south animals tended to spend more time eating fruit and mature leaves (Figure 6). Comparing data from the 2 study areas by season, further regional distinctions emerge. Although in both seasons the southern groups ate more mature leaves and fewer immature leaves than the northern groups (Mann-Whitney U Test, p < .01), in only the wet season did they eat more fruit than the northern groups (Mann-Whitney U Test, p < .008). In neither season was there any regional differ
