The key is know your area and know your birds!This comes from time in the woods and preseason scouting.I find where the birds are traveling at the last part of the day(great if they are frequenting a field,I can just observe from a distance and watch where they go)If I don't locate any that evening I don't fret over it because I have done my scouting and know some good areas to start in the AM.Get in extra early and listen.Good luck
