Very little is known about the specific biology of the Palawan beaded pig other than what has been inferred in the past from observations of the beaded pigs of Indonesia and Malaysia, Sus barbatus barbatus and S. b. oi. However, the Palawan bearded pig is thought to be much more sedentary than Sus barbatus, dispensing with the periodic mass migrations both the subspecies reportedly undertake (4).
All bearded pigs have a diverse diet comprised primarily of fruits and seeds, but also including everything from roots and fungus to small vertebrates and carrion (2) (4). Adult males are normally solitary but the females and young forage in matriarchal family groups, sometimes merging to former larger herds (4). The peak breeding season coincides with the transition from flowering to early fruit formation in the forest, suggesting the pigs may take a visual cue to breed from the falling petals (4). Following mating, the female builds a temporary nest from vegetation in which she will give birth to a litter of 3 to 11 piglets, following a gestation period lasting 90 to 120 days. The nest will only be used by the mother and her piglets for a week to ten days (3) (4).
