AMERICAN WIGEON. 297 



front reddish-brown, extending along under the wing J,o 

 the flanks, which are barred with dark lines ; breast, belly, 

 and vent white ; under tail-coverts brownish-black ; legs, 

 toes, and their membranes dark brown. The whole length 

 is nineteen inches. From the carpal joint to the end of 

 the wing ten inches ; the second quill-feather the longest 

 in the wing, but the first almost as long. 



Wilson says, " the female has the whole head and neck 

 yellowish-white, thickly speckled with black, very little 

 rufous on the breast; the back is dark brown. The 

 young males, as usual, very much like the females during 

 the first season, and do not receive their full plumage until 

 the second year. They are also subject to a regular change 

 every spring and autumn." 



The lower part of the trachea, here introduced from Mr. 

 Audubon's work, is, as noticed by Mr. Blyth, of small 

 size, and decidedly different in form from that of the Eu- 

 ropean Wigeon.
