In my part of the state red fox, Gray Fox, Coon, are the most called animals...I have in past years been calling in more coyotes... However....
I have programmed myself to hunt coyotes like I hunt other predators.. The end results is that you end up getting busted...From field experience
I say that coyotes came into the wind about 80% of the time...The other 20% they came into the the calls any way they saw fit... When they do come in the other directions too they usually come in close to. Makes sense since they can't smell you. However here you are looking down wind most of the times and all of a sudden a coyote shows up from your left your right or from behind you... Maybe when coyotes are the target and it's safe the caller and the shooter should be in a tree stand that they can see everything happening in all directions...When I mean safe..You don't really want to be climbing trees at night time nor if there is ice and snow around...
I have now adjusted my hunting methods... I do not post down wind of the electronic caller all the time now...I first read the terrain to make my decision... If it's a small farm or field.... I now place the speaker in front of me not behind me..If the field is large I will put the caller behind me and try to get cross wind of the main sound beam. One needs to look at the size of the field to determine if the caller should be in front of you or behind you...
