On another note, the early season, fair weather of predator hunting is gone.
After Deer season, less cover, snow, extended periods of cold, less predators and educated predators make calling a bit more of a challenge.
Deer hunters and natural disperal may have some predator species moving into different home ranges the next two weeks.
In season scouting will help for the upcoming mid/late season calling hunts.
This may add up to a 'hot spot' going 'dead', or vise versa.
'Hot spots' may become dead for a number of reasons...
You killed what's there (you may have to wait for the void to fill later in the season), too much human pressure from other hunters (Coyotes are known move out with pressure), Coyote hound hunters (after Deer season) will be hunting full swing and upset your calling plans. 30-40 years ago, I had to deal with Coon hound hunters. Not complaining, but it sure messes things up and I wonder why I can't call anything in, then fine out Coon or Coyote hunters are working the same area.
Late season success requires planning, in-season scouting and a close look at what's happening...
