Javelina Hunting Basics
As with most all these articles let me state that all hunting regulations and hunting information should be studied by the reader prior to any javelina hunting . All states have different hunting rules and regulations so if your headed to arizona to hunt javelina you need to check the arizona state hunting regulations guidebook. Do assume that because you hunt javelina in texas the state rules to the hunt are the same. Get your hunting information and a good hunting map up front and study.
Javelina have very poor eyesight. Most articles and experts will tell you this.  Hunters, writers, and researchers  will all recount tales of how they stalked within 20 yards or even less of feeding Javelina.  I have done it countless times as well.  The key is the Javelina were undisturbed or feeding, wind direction was right, and the hunter made minimal noise. Often times while in feeding mode, Javelina appear to rely more on their sense of smell then eyesight or hearing to alert them to danger. They appear to become engrossed in feeding and often a hunter is successful stalking to very close range.  Generally, herd members will pause in their feeding from time to time to scan and check wind while in an undisturbed state.  I strongly recommend you don't formulate your Javelina hunting strategy on the premise that Javelina eyesight is so poor they can't see you unless you're right on them.  Respect their eyesight at ranges under 100 yards, and remember,  I could recount the numerous times I've been spotted by a herd of Javelina just as easily as the times I was successful at getting in close range.
Predator calling for javelina
Let me first state, predator calling for Javelina should only be used in a situational manner (I'll explain later). If used incorrectly or in the wrong situation, predator calls will prove worthless. In fact, it will scare the Javelina herd away 99.9 percent of the time. Despite predator calling limitations, it's without a doubt the most exciting way to hunt Javelina. Using a predator call exploits the Javelina's propensity to counter attack predators and come to aid wounded or distressed herd mates.
How to use the predator call. The first thing you need to do is purchase a predator call. There are many good choices for under $10, call's that mimic or are advertised as "cotton tail" or "jack rabbit" distress calls work best for Javelina hunting. Next, forget what you know, or think you know, or how you've used calls in the past. Most hunters have "played around" with a call before. You blow into it, it sounds kind of like kazoo or fairly deep "waaaa.... waaaa..." sound. To affectively call in Javelina you want to imitate the sound of a piglet getting the hell chewed out of it. This is done by blowing violently, using your hands to cup the end of the call to mimic the piglet's mouth opening and closing. Imagine what a frightened piglet sounds like, adjust your hands and the "blow" pressure accordingly until you sound like an axe murderer at a teenage slumber party.
 Use a predator call only in three situations.
You've spotted the herd, they are no more than 60 yards away and you can't easily close the distance because of thick brush (to noisy) or it's to open of an area (no cover). Before calling you should "set-up", pistol or bow at the ready, kneeling position, with the location of all animals identified as best as possible. Your call should be on a lanyard, so you can spit it out of your mouth after calling (hands on weapon), but its quickly retrievable if needed. A 3-4 second calling sequence will normally do the trick. As soon as the call sequence is complete, be ready! Javelina will be coming fast. Generally they make 15 to 20 yard charges, stop, and charge again towards the area of the call. You will often hear the "woof" sound they make with each step they take, as there coming in. Stay calm and pick a clean shot. Don't hurry the shot or settle for a bad shot, or worse yet "flock shoot", and don't worry if they see you. I have called in, shot, and missed the same animal three different times with a pistol before, and ultimately bagged him. It can go like this, shoot, miss, the animal runs away, blow on the call, the animal comes back, shoot, miss and so on.
Your humping along (day dreaming) and bang, off busts a herd at 40 yards in 5 different directions. Get on the call (blow) immediately. 3 to 4 seconds, look for animals and listen for "woofing", wait a few seconds and back on the call for another 3 to 4 seconds. Generally, not all the herd will have seen you. Some Javelina may have stayed "frozen" unsure of the exact nature or cause of the alarm, while other Javelina may initially only run 50 -75 yards, then stop and freeze to determine the source of danger. Often times a quick calling sequence will bring the Javelina right back to you for a shot
Moving through thick mesquite tangles and you hear a faint "woof" or smell pig. Although you don't see Javelina, if you hear the telltale faint "woof" sound, then they are in close enough vicinity to respond to a call. The "woof" call is an alert call, similar to a deer's "snort", even when alerted, Javelina still will respond to the call a great percentage of the time.
Cold calling.
Calling blindly, that is, with no Javelina or "hot" sign sighted is unproductive 99.9% of the time.
When Javelina are responding to a call, they are coming to protect a herd member--ready to charge and bite! If you don't think Javelina can be dangerous, your wrong. They can get very, very close, very, very quickly, keep your situational awareness about you. On several occasions I've had to make noise, waive my hand, stand up, kick, etc. to scare off Javelina. this has occurred even after I've shot and bagged an animal. It's very common for Javelina to approach at ranges well under 10 yards when calling. Now thats hunting.
