Good advice and basic's listed by all. /ubbthreads/images/graemlins/grinning-smiley-003.gif
Let me add another on a different note.
TIME
I'f you have the entire night to hunt, (hopefully), and a good looking spot hasn't been as productive as you thought should be, try a different time of night. Best time is usually early darkness, but be willing to vary that to late darkness early light and see if these spots won't turn suddenly good for you.
Coyotes cover quite a distence some nights and what was there last night probably will not be there tomorrow. At least not always.
Geographic location has a lot to do with their travels, but be flexable and try different times.
In fact going back to a spot called early one night with a later call time next day may well pay off.
Catch them starting their hunt, in the middle of there travels, or goung back to their den area. This is what having a large area to hunt helps most with. As with other suggestions, (IMO)mileage may vary!!
