I tried experimenting with this scenario of hunting the same area. I nailed a coyote the first time I hunted it and one escaped before I could reload. I tried calling in the same place the next day--nothing. I tried calling in the same place two days later--nothing. I tried calling the next day--nothing. The wind was out of the same direction every day.
There are a lot of coyotes in this area I hunt and I thought maybe a new one would move in, but so far I haven't seen any new responders. Lots of variables to consider. Coyotes may have a howl or a bark that tells others of trouble in a particular area. These animals are very intelligent and probably remember "conversations" as well as close encounters with us for a long time.
