No they are callable...However if your going with someone hope they are seasoned and know what to do.. Like hiding in the shadows of the tree line, not even going out into the fields at all. Call just where it's legal, Using gray colored camo or gray clothes... No lights from farmer's houses, barn, and or telephone poles behind you. Stand in front of equipment, bale of hay, brush, etc..If the Full Moon is real bad you might even have to use the yellow lens too... The Harvest Moon which is the one that it is ...Seems to be brighter.. Hence the name of it since farmers would work by the light of this moon to harvest crops... Just something that might help is the young first of the year fox might be a bit dumber then their parents and come in a bit easier...
