should be encouraged in every way possible. From Fisher 

 (Hawks and Owls of the United States, pp. 98-100) I quote 

 the following: 



In parts of the West and Southwest this bird often does 

 considerable good in destroying noxious mammals. Dr. J. 

 G. Cooper says : 'The Spanish inhabitants rather encourage 

 its presence, on account of the great number of squirrels it 

 kills ; and I have been told of instances where young ones 

 raised from the nest have been kept for several years in a 

 domestic state, going out daily to kill squirrels and returning 

 to the house at night.' 



"Mr. Lloyd, in a letter dated February 18, 1887, says: 

 'I went to a Bald Eagle's nest on January 28, and though dis- 

 appointed at finding young just ready to fly, yet I watched the 

 parents bring two prairie dogs to the nest, and skins of this 

 mammal were mixed up in the debris of the nest.' 



"What we have said in reference to the Golden Eagle ap- 

 plies equally well to the bird under consideration, namely that 

 over the greater part of the country where the natural food, 

 fish in the present case, is abundant it is a harmless bird and 

 should be protected; while in sections where it is injurious to 

 sheep or other domesticated animals it should not be allowed 

 to become numerous." 



While these birds have been found in all parts of the 

 state, they are never abundant. Bond has mounted several 

 specimens that have been taken in southeastern Wyoming; 

 Jesurun has observed several about Douglas ; West has mount- 

 ed one that was killed at Buffalo ; Allen found them in Wyo- 

 ming during the summer of 1871 ; Cary reports them from 

 the neighborhood of Newcastle ; I have seen this species in 

 Jackson's Hole, at the head of the Green river, DuBois, and 

 Big Horn mountains, west of Buffalo.
