For what it's worth, we called in 6 coyotes on two seperate stands this winter. We also called in 4 coyotes on 3 seperate stands. Inpast years I can think ofone stand that we called7, but several other stands had from 4 to 6 come in. I can tell ya that it's not uncommon to call abunchon a stand during the coldest parts of winter!
The "packs" that we called were probablylitter mates from the earlier summer, along with a parent or two. Not all pups disperse immediately, and as was said, in harshconditions, they very well may stay together and hunt together! Those conditiond do usually mean that small game is harder to hunt and large game is the primary source of food!
