I think temperature and barometric pressure effects tjeir movement more than most anything else. On a warm evening they will often set up in a tree and "air out" rather than come down and feed right away. Barometric pressure change can warn them a storm is coming and bring them out to feed even in daylight hours. Often just watching deer and other wildlife activity can give you a good idea of coon activity. My old hound really starts "talking" to me when he thinks we should be coon hunting!
