I read a good number of these posts. First off, Wolves are not all that smart. They are very aware of their environment, have great noses, excellent hearing and good eyesight. That said, they aren't any smarter than the average German Sheppard, just well adapted to living in their environment. If you study Wolves, their behaviour, food, and social interactions you can maximise your chances of taking wolves regularly.
Wolves primary behaviours are driven by their need for food. The reason they cover large areas is to locate enough food. If food is very plentiful in a much smaller area, their range will contract greatly. They do not travel for fun and adventure, they travel strictly to locate stuff to eat. Wolves up north follow the Caribou herds over long distances, thousands of miles, of migration because that is the only consistent food source. Don't know if it is legal down there, here in Alberta there aren't many rules when it comes to killing wolves, but hunting over bait makes it significantly easier to take wolves regularly. A regularly replenished bait pile will keep the wolves in the area, and coming back for as long as the food lasts. ONLY bait with road kill, do NOT use domestic animals or you will teach them to eat cattle, sheep etc Poison laced bait, when wolves do kill a cow, is a common method of wolf control for a good reason, it works really well and puts them off killing cattle. Like a German Sheppard, wolves do learn from experience.
Wolves are very territorial. They do not like dogs, coyotes or other wolves in their areas. They will actively hunt, kill and eat competing dog species. Also, packs with younger pups and immature adults will often teach them to hunt using coyotes as they are a much less dangerous target than large ungulates and can be run down easier.
If you are restricted to calling wolves, go with someone who is already good at it or hire an outfitter. Pay very close attention to how they setup, how they call and all the things they take into consideration. Becoming good at calling wolves takes a lot of thought and care in how you set up. The actual calling part, especially with electronic calls, is the easy part. Having the right approach paths, wind control, scent control, screening or blinds is all critical. So is being able to stay warm, so heat in the blind means you can stay out much longer.
Best of luck and let us know how you make out.
