Fig. 233. Golden Eagle. g- ra ss, moss, leaves, fur, or feathers, placed in 

 high trees or on a ledge of a cliff. Eggs : usually 2, white, irregularly 

 marked, some almost immaculate, others thickly blotched with brown. 



Food. -- Mainly mammals and birds, including squirrels, prairie dogs, 

 spermophiles, rabbits, fawns, lambs, turkeys, grouse, and waterfowl. 



In his mountain home the golden eagle scours the ridges and sides 

 of precipices for grouse and marmots, and when these become scarce 

 or too wary from long acquaintance with his raids, he descends like 

 a meteor on half folded wings to the valley, where he beats the 

 sagebrush for jack rabbits, sage grouse, or any game worthy of his 

 royal quest. 



The eagles are often seen hunting in pairs, and doubtless find 

 mutual advantage other than companionship in the method. In 

 Salt Lake Valley, at the foot of the Wasatch Mountains, a pair 

 were once found eating a full grown gray fox they had just killed, 

 which it is doubtful if either could have caught or overpowered 

 alone. Under stress of hunger or when game is scarce, the birds are 

 said to take young lambs or kids, and even to eat animals found 

 dead on the prairie, in this way getting the poison put out for 

 coyotes. But only extreme necessity could make them stoop to 

 such ignominious quarry, as nothing short of the extermination of 

 the buffalo and other legitimate game could have brought the 

 haughty chiefs adorned with their regal feathers to beg alms. 



The eagles sweep over the plains and valleys, but the mountains 

 are their natural homes. On San Francisco Mountain in Ari/ona I 

 found a pair coming every morning to drink and bathe in a pool of 

 clear snow water above the timber at 11,000 feet.
