They come through my place every 8 days, spend 2 days checking things out, then move on. If they down an adult deer 3 days. They will have zero to do with road kill deer as you get to much human scent on it by the time you get it off the side of road, into the truck, into the Argo and out in the bush. There strictly nocturnal around my place, and mark their territory about every 50 to 100yds. including the end of my driveway. During super moons we had here in Jan it was -35 to -40F and I wasn't sitting out half the night, illegal anyways. I caught them on camera once at 2:32 in the am. They pick up the camera flash and scent and will not come within 50 yds. of where I set a camera now. Even if I smear the camera with fox urine and set it up on tree while sitting in the Argo so as not to leave a human track in the snow. My camera flash is not invisible as I get deer and bear posing in front of it. Have many pictures of bear teeth and tongues. Good thing the camera is in a heavy metal box.
These wolves I have are used to human presence and as a result are educated, and teach their young well. They will take the family dog right from your yard, many folks in the area over the years have lost dogs, large dogs, one a bull massif to wolves.
This house sat virtually vacant for many years and the local wildlife got used to that. The first year we were here the wolves would stand on the lawn and dare you to say anything, and the deer would eat the flowers etc. out of the front garden after super. I missed a wolf one evening while BBQing and that ended the wolves coming around the house. Couldn't figure out how I missed that wolf until I noticed the hole in the deck railing..!
It is game, one in which they are very good at, as they play it for keeps 24/7/365. So yes figuring out there habits, using the right tactics for the situation, being in the right place at the right time, and good ole sh!t house luck will hopefully eventually pay off. I just bought a wolf howler call and will give that a try when I get proficient in using it. Right now I sound like a wolf with his nuts caught in a barbed wire fence. Which may or may not be a good thing when calling wolves but I would like to sound a little more normal wolf like.
