Fig 4. The frequency of CFEs by baboons and grivet monkeys (N = 95) from April to September 2020 and 2021 shows non-uniform distributions (p < 0.001).

Baboons had more CFEs in the morning (6:00–7:00 a.m.) than in the afternoon (2:00–3:30 p.m.), while grivet monkeys peaked in the early afternoon (11:00 a.m.–12:00 p.m.). No baboon CFEs were recorded between 11:00 a.m. and 6:00 p.m. in both years.
