Table 2.

Chimpanzee (Pan troglodytes schweinfurthii) fecal samples by season and dietary composition.

Dates	Fecal samples/individuals (n)	Fruit species eaten most frequently	Number of food scans (% of scans with preferred fruit)	Proportion of large seeds mean ± SD (minimum–maximum)	Dry matter concentration (% wet weight)
January 6–11	17/17	Ficus natalensis	330 (50)	0.02 ± 0.05^a (0–0.19)	26.0 ± 2.3^a (21.3–29.3)
July 5–19	67/33	Pseudospondias microcarpa	439 (77)	0.42 ± 0.46^b (0–0.96)	35.4 ± 11.8^b (17.2–63.3)
July 20–August 3	46/23	Linociera johnsonii	278 (73)	0.53 ± 0.14^b (0.27–0.75)	31.7 ± 8.7^b (16.3–53.9)

Food scans are the times recorded in KCP’s archive of 15-minute interval behavior scans in which the chimpanzees were observed feeding. For the proportion of large seeds and fecal dry matter concentration, different superscripts indicate significant differences between the seasons.
