Locate food by scent. Will root under logs, rocks, other surface cover, and litter. Dense brush areas, or rock crevices and caves, are required for farrowing. Farrowing sites may be dug in earth and lined with vegetation. Need drinking water at least every 2 days when feeding on dry forage.
Water consumption varies with age, ambient temperature and humidity, and moisture content of food.
Frequent a mixture of dense brush and forest for cover and reproduction, and oak forests and open, herbaceous areas for foraging. Mostly crepuscular and nocturnal, some diurnal activity. More nocturnal in hot weather, more diurnal in cold weather. Boars usually were solitary, or in small male groups, except to breed or to feed on a clumped food resource. Breeding is promiscuous.
