Appendix 1

Observed bird species after Zimmermann et al. (1998), mammal species after Kingdon (1997), number of individuals observed feeding on fruits (N), body mass (Dunning 1993, Kingdon 1997) and weight classes (9 categories). Fruit consumption of some species (fruits/min) after Kirika et al. 2008a (in Ficus thonningii), Kirika et al. 2008b (in Celtis durandii) and Farwig et al. 2006 (in Prunus africana) and mean fruit consumption (fruits/min) per species and weight class (mean). Primates consumed more fruits per minute than birds (ANOVA: F 1,49 = 11.8, p < 0.01, R² = 0.83).
