There usually found in the red woods by the huge mountain, I’m pretty sure there found in other places too, but the red woods works best for me. Also if ur trying to tame one aim for the head with tranqs, but if they get too bloody start aiming at the body.
If you ever encounter one in the wild, and you are in an early stage in the game, run the opposite direction. Also try not to agrovate it unless you are up to the KO/Fight.
Good luck if you encounter it!
