PIED DUCK. 



which passes down the middle, at the back part of 

 the neck, quite to the back : the scapulars are white ; 

 some of the inner ones edged with black, and curve 

 downwards over the wings : back and tail brown : 

 the secondaries are white ; the greater quills are 

 dusky : on the breast is a black band : the belly -is 

 pale brown : the legs yellow : membranes brown. 

 The female is similar to the male : the plumage on 

 the upper parts of the body mottled with dirty brown : 

 the tips of the secondaries white, forming a spot of 

 that colour on the wing : the under parts of the body 

 dirty white : the legs black. According to Wilson, 

 the windpipe or trachea of the male measures ten 

 inches in length, and has four enlargements, viz. 

 one immediately below the mouth, and another at 

 the interval of an inch ; it then bends largely down 

 to the breast-bone, to which it adheres by two strong 

 muscles, and has at that place a third expansion. It 

 then becomes flattened, and before it separates into 

 the lungs, has a fourth enlargement much greater 

 than any of the former, which is bony and round, 

 puffing out from the left side. The sides of the beak 

 are clothed with a loose membranous skin. 



Inhabits the coast of Labrador, and other parts of 

 North America, but in no great abundance.
