Feet Peccaries have 3 toes on each hind foot Behavior Peccaries usually travel in a band from 6 to 12 although as many as 50 have been seen together. They are most active during early morning and evening when it is cooler. Members eat, sleep, and forage together. The exceptions are the old and infirm, who prefer to die in solitude. Herds have a characteristic linear dominance hierarchy, wherein a male is always dominant and the remainder of the order is largely determined by size.
Peccaries tend to remain near permanent sources of water.
Unlike Coyotes and Bobcats, Peccaries are unable to evaporate moisture through panting to prevent overheating. During the fierce heat of midday, Peccaries bed down in the shade and forage when it's cooler. Territories are defended by the rubbing of the rump oil gland against rocks, tree trunks and stumps. Collared Peccaries fend off adversaries by squaring off, laying back their ears, and clattering their canines. In fight, they charge head on, bite, and occasionally lock jaws.
