Often we get a whole herd of Javelinas (collard peccaries), sometimes as many as 20 (once I counted 24). Most of those are females and juveniles. Javelinas are omnivores and will eat small animals, roots, grass, seeds, fruit, and cactus although their most cherished food comes from our garbage cans; oh, and any plant we buy from a nursery. Javelinas have scent glands below each eye and another on their back. The scent glands are used to mark herd territories. They also rub up against each other to mark members of a herd. So, while each Javelina has it's own scent, each herd also has its own scent. The scent is strong enough that humans can easily pick it up -- probably why Javelinas are also referred to as "skunk pigs."
