Find a fresh track and follow. I've walked one down, it isn't that difficult. A lot of lions killed in SD that way. When they figure out you are following them they will start looping back and watching you. Then have to watch behind as well as in front of you.
If you are going to call your time is better spent with a plan rather than just random calling with random sounds. Lions mate and eat. They dont have a defined breeding season.
Try to cut fresh tracks then follow them. If they are going in a fairly straight line lion isn't hungry and looking for a mate. If they are wandering back and forth, in and out of bushes they are looking for food. Once you figure out what they are up to start looping way out in front of the tracks, best if you have roads to do it on. If you cut the track loop again. When you don't cut the track the lion is somewhere between you and the lady set of tracks. Set up and call with sounds based on what they are doing.
