720. F. marl'la. (Qu. proper name? Qu. Gr. fj.ap'i.\r), marile, charcoal, from the pitch-black 

 fore-parts?) Greater Scaup Duck. Bkj Black-head. Blue-bill. Kaft Duck. 

 Flocking Fowl. Shuffler. Adult ^ : No ring around neck. Speculum white. BiU 

 dull blue, with black hooked nail, broad and flat at end, where considerably wider than at 

 base. Iris yellow. Feet livid blackish, or dark yjlumbeous, witli darker webs. Whole head, 

 neck, and fore-parts of body pitch-black, on the head with chiefly green iridescence. Lower 

 back, rump, tail, with both upper and under coverts, black or blackish. Middle of back, 

 scapulars, and most of under parts, white, the interscapulars, scapulars, sides of body, flanks, 

 and lower belly waved with fine zig-zag cross-lines of black, quite in "cauvas-back'' style. 

 Wing-coverts similar to back, but darker gray and more obscurely marked; the greater 

 coverts tipped with black, forming the anterior border of the white speculum, which is formed 

 by the secondaries, the white extending quite across them, their tips black. Primaries 

 brownish-black, becoming gray inwardly. Axillars and most of under wing-coverts white. 

 9 ; BiU, eyes and feet as before. The black parts of the $ replaced by dusky or dark brown, 

 which latter is the color of the head. A broad belt of pure white around base of upper 

 mandible, forming a conspicuous white "face." The black-and-white vermiculation less 

 distinctly developed. Length of <J $ 18.00-20.00; extent 30.00-35.00, usually over 30.00; 

 wing 8.50-9.00 ; tail 3.00 ; biU 3.00 ; tarsus 1.50; middle toe and claw 2.60. Europe, Asia, 

 etc., and N. Am. at large; on the whole more northerly than F. affinis, not proceeding so 

 far south in winter, though breeding no farther north — from N. borders of U. S., northward. 

 The more frequent U. S. scaup in winter is F. affinis. Nest on ground, down-bned; eggs

 characters, though constantly associated with the last. N. Am. at large ; breeds from the 

 N. borders of the U. S. northward ; winters in and migrates through the U. S. to C. Am. 

 and W. I.
