Within the decade it became obvious to Park officials that the fauna would not long survive this savage onslaught from squaw men, professional gunners, fierce dogs, and expert scouts and guides vying for tourist patronage. Along with this realization came another discovery; soldiers in remote stations had formed enjoyable companionships with wilderness creatures. These lonely men were delighted by the universally charming wild life trait of responding with confidence and alacrity to friendly human advances. It became increasingly apparent to the officials that Yellowstone birds and mammals would quickly recognize overtures of friendship and protection. The idea was advanced that nearly every species in the Park might become as tame as range cattle if given an opportunity to move safely within rifle-shot for several years. Recommendations to that effect forwarded to the Secretary of the Interior by Superintendent Norris in 1879 were passed on to Congress, and they played an important part in the passage of legislation on March 3, 1883, under which the killing of game was first suppressed. In subsequent years the laws were strengthened and administration improved. This was the beginning of wild life conservation practice by the federal government. Since then the various species of native fauna have achieved a generally satisfactory balance. The Park’s policy of protection can definitely be credited with saving the grizzly bear from extinction, and the trumpeter swan is receiving his chance to survive. It may be too late in this case. Today the alert tourist may reap the reward of that wise and fruitful policy in observing mountain sheep, antelope, mule deer, elk, moose, coyotes, marmot, and squirrels as they roam around in the Park. Indeed, the quiet but energetic visitor who ventures upon the forest trails may even see the rare sand-hill crane and trumpeter swan. Besides, he will frequently hear the passing whisper of the honker’s wing. Actually, he may “shoot” both birds and mammals with the camera and take home trophies of everlasting enjoyment.
