When dealing with the overgrown, unmanaged jungle, I would look for the areas they like to feed and travel through. Then just move slowly or wait quietly. There are spots near roads, especially with a fork or spur road, with lots of shrubs and heavy low growth. The long straight sections, tend to have less of the shrubs and more of the overplanted conifers. Seems like they like to hang back in the overgrown timber where they have some sight distance and then sneak into the little feeding areas. Also, if possible on you walks, look for alders with ferns that might be off to the side of the roads you're stalking.
