Jiange. — Northern hemisphere; in America, breeds in the interior locally 

 from Kansas northward to the arctic regions ; known to breed on the Atlantic 

 coast only at Anticosti ; winters from Virginia to Florida and Texas. 



Washington, common W. V., Sept. to Apl. Long Island, A. V. 



Sffgs, eight to twelve, pale buff or bufty white, 209 x 1-57 (Eidgw.). 



This species is common in the interior and in Florida, but is rather 

 rare in the other Atlantic States. Its call-note is said to resemble that 

 of the Mallard, " but is rather more shrill, and frequently repeated."

^marfe.— The females of the European and American Widgeons bear a 

 general resemblance to one another. Their distinguishing characters are 

 mainly in the color of the head and throat, which are brown in the European 

 species, and in the color of the greater wing-coverts, which are whiter in the 

 American bird. I have seen a caged male in the summer in a plumage closely 

 resembling that of the female. Probably a similar change of plumage occurs 

 in our A. ainerieana. 



^an^«.— Northern parts of the Old World; in North America breeds in 

 the Aleutian Islands, and occurs occasionally in the eastern United States. 



Washington, A. V., two records. Long Island, A. V. 



Eggs, five to eight, bufty white, 2-23 x 1-53. 



" The call-note of the male is a shrill, whistling wUe-you, whence 

 the local names ' Whew Duck ' and ' Whewer ' ; but the female utters 

 a low purr-ing growl. Both sexes, however, rise in silence " (Saunders). 



\St. Anas americana Gmel. Baldfate; American- Widgeon.
