Marty,
If you can figure out what makes them turn on one day and off the next, then you'd be a very rich man. /ubbthreads/images/graemlins/smile.gif
I've been night calling, where we couldn't draw a blank stand on one night. We called up 36, but conditions were the same the following night and we couldn't draw a single response. After 5 blank stands, we had to change something as time was ticking. The trick that salvaged the second night was using howling -vs- distress. What made distress so successful on one night and not the next? Who knows? But luckily we adapted and figured out something to salvage the night. Thank God, as the pressure was on me to call up coyotes for Jeff and Todd...they would have never let me live it down. /ubbthreads/images/graemlins/grin.gif
I've seen this happen a bunch of times on day calling trips, as well. Conditions the same, moon phase is the same, wind speed and direction is the same. Called 20 in on one day and only 4 on the next. Though, howling responses proved that there were plenty of coyotes that heard the calls on each stand.
We found that calling slows down around Iowa when certain berries hit their prime and scat is filled 100% with their seeds. Try to find fresh scat and see what is on their menu. /ubbthreads/images/graemlins/confused1.gif
Figuring them out is all part of the quest.... /ubbthreads/images/graemlins/grinning-smiley-003.gif
