Hunted wolves all last winter and as far as I can see they do live in the same area as coyotes but only in that dead area/boundary ADCcoyote mentioned. There may be some exceptions but that's what I saw.
Once you get further into the bush and further away from roads,power lines, pipe lines, and houses I didn't see a single coyote track all winter.
Wolves and Red Fox seem to often share the same areas though.
Sorry no hard facts Chan and welcome to the board! Ryan
