The javelina is a large mammal, 40 to 55 pounds, that resembles a small wild boar. Both males and females have long, sharp canines, the “javelins” for which they are named. They are common throughout the Sonoran Desert, preferring areas with large amounts of prickly pear and cactus, which is their favorite food. They live in highly social and communicative groups, and they have at least 15 different types of calls signaling alarm, submission, and aggression. An older, experienced sow leads the herd, determining when to bed down, feed, or go to water. Javelina have no defined breeding season; the babies, usually twins, can be born in any month. Not many predators other than a mountain lion will attack an adult javelina, but the babies are prey for coyotes, bobcats, and other animals.
