the first thing you need to do before you leave the house is decide what you want to hunt,fox or coyote.generaly speaking you don't do both at the same time.although when working coyotes with howlers and distress sounds you might get a gray to come in,reds will have no part of it.with out seeing what you are doing wrong its hard to say what the problem is.since reds are your main target,are you keeping your volume down?? reds are volume sensitive and will shy away from volumes that you might use for grays and coyotes.of course when working fox you might get a coyote to responed so there again decide what you want,fox or coyote.the fox will most times come in first,especially the grays.fox hunting at night will be ten fold more productive then day time hunting.during that golden hour of first light and last light is also good.the best conditions for any predator hunting is extremely cold weather,the colder the better.throw in 6 inches of snow and you have perfect conditions.times of deep powder snow(over a foot deep)will accualy hurt the predator hunter.but after the first semi thaw when the remaining snow gets a crust on it,this is also a real good time to get out hunting.howler said it,details.small over looked details can and will ruin a coyote hunt before it starts.the experts claim that a coyote can hear a mouse under a foot of snow at 500 yards.i have never had the oppertunety to test this at 500 yards, but have at well over 300.one morning i took a stand and was giving things a few to calm down before calling,a coyote happened to stroll by.in my pocket i had a mouse squeeker.i gently squeezed it,it produced a very muffled soft bearly audible sound.the coyote instantly stoped and looked right at me.i was amazed to say the least.would he have heard it at 500 or more yards?don't know but he did at over 300.the coyotes hearing is impeckable so hunters who whisper to each other and make to much noise going to the stand are busted before they get started.this is one of the details howler is talking about.did i get that coyote??not hardly.this was totaly unexpected and i was no where near ready to pull the trigger.i was hoping he would circle around to find that mouse but he never showed.
