Although a claim that Mowat makes was that he interacted closely with a wolf pack alone in order to study them, the first wildlife biologist to successfully use the method of habituation to study and follow wild wolf packs in close proximity was fellow CWS scientist and International Wolf Specialist Group Canadian representative Dr. Lu Carbyn, in a 1970s study in Jasper National Park. Although also pointing out "Never Cry Wolf"'s fictional rather than factual nature, his remarks were less critical, calling Farley Mowat's book "Good fiction and good reading".
