Where to hunt for pigs in Far Cry 3

I've played the game and looked through the wiki, there is no use that I've seen for the miscellaneous items that you gather from loot chests and dead bodies. The names for everything is just filler, make the player feel a sense of pride when he picks up a Diamond or Smartphone. The only quest items you will gather would be herbs and leather, occasionally some other item that you can only get while performing the quest.

The reason you aren't finding any boars is because there are very few areas where they are common. For example I've unlocked 8 Radio Towers and have only opened up one area that has them.

Here is the the best screenshot I could take that should allow you to figure out how to get to the boars. Also pointed out what a pig is so you know the difference.
