Look at the tracks and what's in the scat i.e what they are eating, water, washes, plus little ravines with brush in them where they might be hiding. They don't see very well and you can usually follow them or circle to get a shot. Head em off at the pass so to say. If you find a place with green vegetation especially any kind of green plants it's like a grocery store to them and they might not venture too far unless they totally destroy the green area. A friend of ours in town had an bunch of Javelina get in her flower beds and they ate until they couldn't move and this is in town, she was so pissed. If the javelina are there and it looks like they are , prickly pear is major food source for them in AZ and they get liquids out of them , I guess that's one reason why they survive so well, although they don't tolerate extreme cold very well, but we are seeing more and more up on the mtn where we live in the more summer months and retreat back down to lower elevations in the winter months.
