Without actually walking around the property, I agree with most of what was said above -- see if you can find a spot that overlooks that narrow bottleneck of trees between the two plowed fields. That is a likely crossing point from animals moving through the area, though you will need to confirm it by walking through and looking for sign. It's also the place that is most inslulated from the roads, houses, etc., which make is a likely place for animals to use.

Notice, too, the narrow strip of grass just below the house? That is essentially a third "field" with yet another corner near that narrow bottleneck of trees.
