The abundance of bird-life in one of these rookeries is quite astound- 

 ing. In this group are roseate spoonbillSj sno\\y egrets, 

 Flonda American egrets, little blue herons, Louisiana herons, 



Q ibises, cormorants, and water turkeys. Because of the 



great inaccessibility of this island it has been one of the 

 last places to escape the depredations of the plume-hunter. (Repro- 

 duced from studies in the Everglades of Florida.) 



The golden eagle is one of the most \\idely distributed of birds. In 



North America it is now most common in the region from the Rockies to 



the Pacific Coast, although it is found as far east as Maine. 



Golden ag e g^Qj.jgg ^q i\^q contrary notwithstanding, the eagle never 



attacks man, even though the nest is approached. 



Its food consists of rabbits, squirrels, woodchucks, and occasionally 



sheep. (Reproduced from studies near Bates Hole, Wyoming.) 



The abundance of bird life in this western lake beneath Mt. Shasta, 

 which is seen in the center of the background, is astonishing.
