When we are calling wolves in Canada, we get in a lot of fox and lynx coming into the call. Usually if they come in, you will not get a wolf in. They know when there is a wolf in the vicinity and refrain from coming in. There are some great color variations of fox in Ontario, silver, red and cross fox, that all make great mounts. The lynx cannot be taken while calling, the trappers are in control of all the lynx permits, and can only be taken by trap. It is real tough to get one in and just have to watch it until it decides to leave.
