 man. It lives in the most elevated situations, and 

 where no other animal or vegetable can exist, 

 making its home on the very highest ridges of the 

 Andes in South America. From these vast heights 

 it soars still higher, and then looks clown on the 

 plains, three or four miles beneath it, for its prey. 

 It lives upon carrion, and destroys deer, vicunas, 

 and other animals, which it carries to its "aery." 

 This immense bird builds no nest, but places its 

 eggs on the bare rock. During the time it is rear- 

 ing its young ones it commits terrible ravages 

 among the cattle and herds of wild horses with 

 which the extensive plains of its native country 

 abound.
