Still hunting is my favorite style of hunting. I love moving and spotting game before they spot you. Although difficult at times, this method of hunting provides the most exciting and enjoyable experience for me.
One tip I have learned from years of still hunting is to approach animals from above, when possible. During afternoon hunts when animals typically are not moving and retreat to their bedding areas, I like to move through those bedding areas very slowly and carefully in a downhill direction. Most animals will bed facing downhill and unless the terrain has unusual features such as rolling benches down a draw, the animals will almost always be facing downhill. This allows the patient still hunter the opportunity to spot these bedded animals without being detected himself.
Of course, the wind direction needs to be considered when evaluating your downhill approach, but this technique can be very useful in virtually any downhill scenario from draws, mountainsides, ravines and ridges. A slow and methodical pace with frequent pauses for glassing will many times lead to a great shot opportunity on bedded animals.
