Peccaries (javelinas) live in herds of up to 100 (possibly over 100 for white-lipped peccaries) individuals. Living in herds brings security in that predators will not charge into a group of prey; they must separate one from the group. Also, if a predator gets too close, a peccary may rub its tusks together in warning. If the predator does not go away, it may even hit it with its tusks.
Javelinas are most common in the Chihuahuan and Sonoran Deserts.
