water plants, small mollusks, and tadpoles. When fully 

 grown they delight in beech-nuts, acorns, and such berries 

 as may be found in their locality. 



These elegant birds, 'so delicious for the table, and 

 so easily domesticated, spend their winters on the 

 fresh waters of the more southern portion of the 

 Union. Indeed, they are always strictly fresh-water ducks, 

 and may sometimes be found in large flocks during fall and

 when he rose, he pursued his abruptly-curved pathway with

 sweep of the Buzzards. Though not numerous anywhere, 

 this bird has very nearly or quite the wide world as its 

 range. It is well known all along the Atlantic Coast, and is 

 more or less common along the great rivers of the interior, 

 in the mountainous regions of which it breeds, the nest, 

 like that of the Golden Eagle, being placed on ledges of 

 projecting rock on some lofty precipice. Professor S. S. 

 Haldeman was the first to note its breeding in the United 

 States, discovering the site of its nest in the mountain-
