Habitat
Oliver's warty pig primarily inhabits dense forests, including primary and secondary growth areas, as well as grasslands and agricultural edges in the Philippines, especially on Mindanao and nearby islands. They prefer elevations from sea level up to about 1,500 meters, where they can find cover and food sources. This species adapts to both lowland and montane environments but avoids open areas.
Diet
Oliver's warty pig is omnivorous, feeding on roots, tubers, fruits, and leaves, as well as insects, earthworms, and small vertebrates. They forage on the ground using their snout to dig, typically during dawn and dusk to avoid predators. This feeding behavior helps them exploit a wide range of available resources in their habitat.
Behavior
Oliver's warty pig is primarily nocturnal or crepuscular, spending days resting in dense vegetation and becoming active at night to forage. They live in small family groups led by a dominant male, exhibiting territorial behavior where males mark and defend their areas. Notable behaviors include wallowing in mud to regulate body temperature and deter parasites, as well as vocal communications for social interactions.
Conservation Status
Oliver's warty pig is classified as Vulnerable by the IUCN due to habitat loss from deforestation and hunting pressure. Population trends are decreasing, with major threats including agricultural expansion and human encroachment.
