The plant species are arranged in descending order of mean weight of food eaten per bout (% contribution by each plant species was estimated by calculating the average wet weight of each food item eaten per day for all food items during full day follows and converting the value obtained as a percentage of total weight of food eaten per day). Empty cells imply that data was not recorded for full day. Where F: fruit, L: leaves, B: bark, P: pith, and g/min: grams of food ingested per minute.
