What Are Javelinas? The Desert’s Misunderstood “Wild Pigs?”
What are javelinas
If you live in Arizona, chances are you’ve seen or heard about javelinas roaming neighborhoods, especially at dawn or dusk. But what exactly are these animals—and are they dangerous?
Javelinas, officially known as collared peccaries, are often mistaken for wild pigs. However, they’re actually a completely different species native to the Americas.

Not a Pig: Meet the Collared Peccary
The collared peccary (Pecari tajacu) is a small, hoofed mammal with a stocky build and coarse, bristly fur. They get their nickname “javelina” from Spanish, meaning “little javelin,” referring to their sharp tusks.
- Length: 3–4 feet
- Weight: 40–60 pounds
- Color: Gray to black with a lighter “collar”
- Distinct trait: Strong musky odor from a scent gland
Where Do Javelinas Live?
Javelinas thrive in desert environments and are commonly found across Arizona, including the Phoenix metro area. As urban development expands, encounters with humans have become more frequent.
Behavior: Why You See Them in Groups
Javelinas are social animals that travel in groups called “squadrons,” typically made up of 6 to 12 individuals. These groups help protect them from predators and navigate their environment.
They are most active during cooler parts of the day—early morning and evening—especially during Arizona’s hot summers.
What Do Javelinas Eat?
Despite their tough appearance, javelinas are herbivores. Their diet mainly includes:
- Prickly pear cactus (a favorite)
- Mesquite beans
- Roots and desert vegetation
Are Javelinas Dangerous?
Javelinas are generally not aggressive toward humans, but they can become defensive if they feel threatened—especially if they are protecting their young or are approached by dogs.
Important safety tips:
- Do not feed javelinas
- Keep pets on a leash
- Secure trash and outdoor food sources
- Give them plenty of space
Why Are They Showing Up in Neighborhoods?
Urban expansion into desert habitats has increased human-wildlife interactions. Easy access to food—like garbage, pet food, and landscaping plants—also attracts javelinas into residential areas.
Final Thoughts
Javelinas are an important part of the desert ecosystem and usually pose little risk when left alone. Understanding their behavior is the key to peacefully coexisting with these unique animals.
