 around black, each feather with a border and an internal ring of white, giving

 chestnut on wing-coverts ; speculum ashy gray and white ; axillars and under

Range. 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. 



Eggs, eight to twelve, pale buff' or butty white, 2-09 x 1-57 (Kidgw.). 



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." 



136. Anas penelope Linn. EUROPEAN WIDGEON. Ad. $ . Crown 

 creamy butt'; throat blackish, rest of head and neck rufous-brown ; upper 

 breast vinaceous, lower breast and belly white ; sides and back finely marked 

 with wavy black and white lines. Ad. 9 . Head and throat deep oehraceous- 

 buff, finely streaked and barred with black, darker above ; upper breast and 

 sides much the same color, but without black markings ; lower breast and 

 belly white ; back grayish brown, the feathers with small ochraceous buffy 

 bars; tertials fuscous, bordered by deep ochraceous buffy ; greater wing-cov- 

 erts brownish gray, usually whiter on the outer webs and tipped with black.

Remarks. 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. americana. 



Range. 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, buffy white, 2-23 x 1-53. 



"The call-note of the male is a shrill, whistling ichee-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). 



137. Anas americana Gmel. BALDPATE; AMERICAN WIDGEON. 

 Ad. <J . Middle of the crown white or buft'y ; sides of the crown, from the eye
