Energy content of foods analysed, and relative time spent feeding on each food item in different seasons during this study.

“Part” indicates the part of the plant or if it is an insect species consumed by gorillas: BK = bark, FR = fruit, IN = insect, LV = leaves, SEED-DUNG = seed ingested from coprophagy, ST = stem, YLV = young leaves. DE = digestible energy calculated with equation (6). Energy Lab = energy values from bomb calorimetric method. “% Feeding time” is the percentage of total feeding time from focal scans. “% Feeding in HF” and “in LF” is the % of feeding time on important food as ≥1% of the feeding time of each of the two seasons with HF = high fruit season and LF = low fruit season.
