Javelina

The weight figures differ by source, and the spread is more useful than an average. The general published range for an adult javelina is 30 to 60 pounds. Inside that range, Arizona Game and Fish Department cites males averaging around 65 pounds and females around 50, while Texas Parks and Wildlife Department cites a typical adult at 35 to 45 pounds with some individuals in the 50 to 60 pound range. Those are two state agencies measuring two different populations at opposite ends of the animal's US range, not a contradiction to resolve. The number that matters for identification is the floor and the ceiling, because the highest figure any of these sources cites for a javelina still sits below the low end of the feral hog range.

Breeding is continuous rather than generational. There is no seasonal generation count for this species the way there is for an insect. With a roughly 5 month gestation and no closed breeding window, a single female can carry more than one litter across a calendar year, which is why herd size on a given range tracks habitat quality more closely than it tracks the calendar.

A javelina is not a pig

That is real taxonomy rather than a technicality. Javelina belong to the family Tayassuidae, the peccaries, which is a separate family from Suidae, the family that contains true pigs and feral swine. Peccaries are a New World family and pigs are an Old World family. They are only distantly related, and they cannot produce fertile offspring together. Every other identification point follows from the fact that these are two different animals that happen to look alike from a distance.

Size settles the feral hog mix-up

Size settles most feral hog mix-ups on its own. Adults stand 18 to 20 inches at the shoulder, run about 3 feet long, and weigh 30 to 60 pounds. Feral swine run 75 to 250 pounds and up. If the animal is big enough to make you reconsider the size of your fence, it is not a javelina.

One color pattern, and that is the tell

There is exactly one color pattern, and that is itself the tell. Coarse grizzled black-and-gray salt-and-pepper hair, with a lighter band of hair, the collar, running across the shoulders and neck. That collar is where the name collared peccary comes from. Feral swine come in white, black, brown, and red in almost any combination, frequently blotched or spotted. Wide color variation rules a javelina out.

No visible tail, and small rounded ears

A javelina's tail is a tuft of hair at most, and is usually not visible at all. Feral swine have a clearly visible tail and larger, longer, pointed ears. Snout shape backs this up: a javelina's is shorter and more concave, a feral hog's longer and more pointed.

The tusks are straight, not curved

Javelina have well-developed canine tusks built for slashing that run straight up and down, rather than the curving boar-style tusks a feral hog carries. This is also the feature behind the dog-injury risk.

A mane that stands up when alarmed

A dark dorsal mane that stands erect when the animal is alarmed. It runs from the head to the base of the tail and raises like a hackle, which makes the animal look considerably larger than it is. A javelina with its mane up is a javelina that has already noticed you.

You may smell the musk gland first

The musk gland is a physical feature you can often smell before you see the animal. It sits on the lower back, several inches above the tail, and puts out a strong skunk-like odor. It is not a rear-facing spray gland like a skunk's, and there is no spraying involved. The odor simply comes off the animal.

Details from tracks or a carcass

Less visible but genuinely diagnostic details, if you have tracks or a carcass to look at. The outer dewclaw is absent from the hind feet, so a javelina leaves three hoofed toes on the hind foot against a true pig's four. The stomach is three-chambered and non-ruminant, adapted to a fibrous cactus diet. There are fewer teeth than a true pig has, and females carry only two pairs of mammary glands, set low on the abdomen between the hind legs.

Shallow digging, rarely 2 inches deep

Shallow digging, rarely more than 2 inches deep, is the single most useful sign. Javelina dig for roots, tubers, bulbs, and grubs just under the surface. Feral swine root deep and turn ground over wholesale. If the disturbance in a planting bed is broad and shallow rather than deep and churned, that points to javelina, and it points away from the far more expensive problem.

Torn-up planting beds

Ornamental cactus, succulents, and bulb beds take the worst of it. These are javelina's actual preferred foods rather than incidental targets, which is why landscaping choice matters so much.

Shredded prickly pear pads

Look for tooth marks and missing spines in a small radius. This is close to a signature. A javelina drags a pad along the ground with a forefoot to break off the largest spines, then holds it down and shreds it with its canine teeth. The damaged pads and the scattered broken spines usually sit within a few feet of each other.

Chewed irrigation hose and drip line

Javelina chew water lines going after moisture, and in dry habitat this is one of the more common ways a herd first announces itself on a residential property.

Cloven tracks, in pairs

Cloven pig-like tracks, roughly 1 to 1.5 inches, in pairs. They are slightly narrower and more delicate looking than a feral hog's track, and the missing hind dewclaw is the confirming detail if the print is clean enough to read.

Flattened bedding under cover

Flattened bedding areas under dense brush, porches, decks, sheds, and crawl spaces. A herd will reuse a bedding site for several days before rotating 200 to 800 yards away, so a flattened area that looks abandoned is often still in the rotation.

A rapid tooth-popping sound

A rapid tooth-popping or jaw-clacking sound, described as like two bones striking together about four times a second. This is an alarm and threat display, and it is specific enough to confirm the animal without seeing it. Grunts, growls, barks, and a low whoof round out the herd's vocabulary.

Skunk-like musk with no skunk

A strong, pungent, skunk-like musk odor with no skunk anywhere. Multiple independent sources describe javelina as an animal you smell before you see. The odor comes from the dorsal gland rather than a spray, and it intensifies when the animal is startled.

Never trap or relocate one

Do not attempt to trap, kill, or relocate a javelina yourself. This is the first item on the list for a legal reason, not a cautious one. Javelina is a regulated big game species in all three states where it occurs. Arizona Game and Fish Department states outright that it is unlawful to trap javelina, and that it is unlawful to injure or kill game animals unless rigorous provisions under the law have been met. New Mexico requires a draw-only javelina license with a limit of one and mandatory harvest reporting. Texas classifies javelina as a native big game species, harvestable only with the appropriate license in specified counties. Rules of this kind vary by state and by county and they change, so verify current state and local wildlife regulations before taking any action, and route the problem to your state wildlife agency or a licensed nuisance wildlife control operator rather than buying a trap.

The Texas contrast

It is worth stating plainly, because it is where this goes wrong most often. Texas treats feral hogs as unprotected free-ranging livestock a landowner may remove at will, and treats javelina as a native big game species with a license requirement and a mandatory harvest of the meat. A Texas landowner cannot treat a javelina the way they can treat a feral hog. Getting the identification right is the difference between a legal removal and an illegal one.

Relocation usually kills them

Relocation usually kills the animal even when a professional does it. Arizona Game and Fish Department describes removal of a problem javelina as a genuine last resort, contingent on documented severe or repeated property damage after attractant removal has already failed, and notes that relocated javelina frequently do not survive, because of unfamiliar terrain, separation from their own herd, or territorial conflict with a resident herd. Relocation is not the humane middle option it sounds like.

Never feed javelina

There is no circumstance that makes it acceptable. Wildlife agencies put this above every other prevention measure. Feeding, whether deliberate or through unsecured food, is the single largest cause of javelina losing their natural wariness and turning into a persistent and occasionally dangerous neighborhood problem. Arizona Game and Fish Department asks that illegal feeding be reported to the department directly, so a neighbor feeding a herd is something the agency wants to hear about.

Remove the food attractants

Remove food attractants specifically. Feed pets indoors, or put out only what they will finish in one sitting. Do not let birdseed accumulate on the ground, and consider fencing bird-feeding areas. Store birdseed, livestock feed, rodent bait, and pet food indoors. Pick up fallen fruit and nuts promptly. Secure garbage cans with locking lids or by strapping them to a fence, and put cans out the morning of pickup rather than the night before.

Remove the water too

Remove water attractants too, which matters more for javelina than for most wildlife. Javelina get most of their water from prickly pear, and a reliable water source in a dry yard is a strong draw. Keep pet bowls, pools, and ponds elevated out of reach or behind secure fencing, and repair leaking irrigation lines and hose bibs the animals chew for moisture.

Choose resistant landscaping

Choose javelina-resistant landscaping rather than guessing. University of Arizona Cooperative Extension publishes a survey-based javelina plant resistance rating guide, built on prior research plus directly reported herbivory from residents and businesses, that sorts plants into never-to-rarely damaged, sometimes damaged, and frequently damaged. Cacti, succulents, bulbs, tubers, and most tender new growth sit at the wrong end of that list.

Physical exclusion, with specs

For anything javelina do want, physical exclusion is the reliable fix, and the specifications are sourced. A solid block wall or well-maintained chain-link fence at least 4 feet tall, with a concrete footer buried 8 to 12 inches deep, since javelina will dig under an unprotected fence base. For a garden bed specifically, a single-strand electric fence set 8 to 10 inches above the ground works, though local ordinances should be checked before installing electric fencing.

Skirt the space under structures

Skirt or screen the cave-like spaces under structures. Porches, decks, mobile home undersides, and crawl spaces are all places a herd will bed down repeatedly once it finds them. Closing those gaps is ordinary exclusion work and it is one of the few javelina measures a homeowner can fully handle alone.

Leash dogs and fence the yard

Keep dogs leashed and yards fenced, and treat this as the top pet-safety measure. Dogs are the most common trigger for a defensive javelina response, for reasons covered in the next item. Arizona Game and Fish Department, University of Arizona Cooperative Extension, and Texas Parks and Wildlife Department all land on the same recommendation independently.

The dog conflict is the top risk

The dog conflict risk is the best-documented risk of the lot, and it deserves real weight. Arizona Game and Fish Department states directly that javelina may act defensively when they hear or smell a dog, and that dogs and javelina can seriously hurt or kill each other. The department's Tucson region has described dog encounters as the second most common catalyst in aggressive javelina encounters, behind only illegal feeding, and noted that puncture wounds from javelina canine teeth can cause severe injury. Texas Parks and Wildlife Department corroborates the same pattern independently from the Texas side, reporting that many dogs have been crippled or killed trying to attack javelina. The mechanism is not aggression for its own sake. Dogs resemble coyotes, one of javelina's natural predators, so the javelina defends itself or its young. University of Arizona Cooperative Extension separately documents javelina attacks on leashed dogs in cases where the animal had been previously fed by well-meaning homeowners and had lost its natural wariness.

Risk to people is real but rare

The charging javelina story has a specific explanation. Arizona Game and Fish Department calls human-javelina conflict rare overall, and Texas Parks and Wildlife Department calls aggressive encounters with humans very, very rare, with both agencies attributing most human bite incidents to illegal feeding rather than to chance encounters. The apparent charging is largely an artifact of eyesight. Javelina see poorly, with Arizona Game and Fish Department noting difficulty recognizing objects beyond about 100 yards, and they compensate with keen smell and hearing. When a herd is alarmed, individuals scatter in every direction rather than retreating together, so one animal often ends up running toward a person by chance. Give a startled herd room and a clear direction to leave.

Rabies, kept in proportion

Rabies is documented in javelina but is uncommon, and it should be kept in proportion. Javelina are not classified nationally as a primary rabies vector the way raccoons, skunks, foxes, and bats are. Arizona Game and Fish Department confirms javelina can catch rabies and describes the symptom picture, which runs either toward foaming at the mouth and erratic hyperactive behavior or toward fearful, lethargic, or paralyzed behavior. A CDC report documents a lab-confirmed case in Arizona after a javelina bit a hunter, which the agency called the first documented report of rabies in a javelina, and noted that javelina bites most often happen in a hunting context rather than in a random encounter. Anyone bitten should seek immediate medical attention, and the animal will need to be captured or killed and tested. Some sources also note that javelina can carry canine distemper, which is transmissible to pet dogs, though that is a single-source observation rather than an established clinical finding.

Call for repeat bedding or a bite

Call a professional or your state wildlife agency for any repeat bedding under a structure, any bite or injury to a person or a pet, or any animal behaving abnormally. Repeated bedding under a porch or crawl space means the herd has added your property to its rotation and closing the gap needs to happen while the space is empty. A bite is a medical question first and a wildlife question second. And an animal showing the behavior changes described above needs an agency response, not a homeowner one.

Call before handling the animal

Call before doing anything that involves handling, confining, or removing the animal. Given the game species classification in all three range states, the practical threshold for calling is lower than it is for most wildlife. If the fix involves a trap, a firearm, or moving the animal anywhere, it is a call to make rather than a project to start.
