Several dozen subspecies. Not to mention them many "interactions" with other greys, coyotes and domestic dogs. If they want to monitor them, better they stay in the US anyway. Or email Mr. Goodbar to go a little further west and turn south at the NM bootheel. No fence there. Or as others, hire a coyote. Either to guide him or to avoid a return trip to traffic him a young female wolf.
Serious dilemma for the wolf; when the Coyote delivers the bitch she’ll be knocked up.
