Also takes animal food on an opportunistic basis, often below the canopy, and especially during the breeding season to feed protein to the young. In a tropical rainforest of southern Thailand, among non-fig fruit Polyalthia sp (Annonaceae), Aglaia spectabilis (Meliaceae) and Oncosperma horridum (Arecaceae) are dominant. Feeds mainly on fruits, especially many figs, but also lipid-rich capsules and drupes. From sea level and coastal swamp forest into lower montane forest, recorded to 1,400 m elevation.
