This small Duck has won deserved distinction through its powers 

 as a diver. Like the Grebes, it " dives at the flash," though this well- 

 worn expression has lost half its meaning since flintlocks and percus- 

 sion caps have become things of the past. The Buiflehead feeds to 

 some extent on small fish, which it pursues and catches under water. 



154. Clangula hyemalis (Linn:). Old Squaw ; Old Wife; South 

 SoDTHEELT. Ad. 6 in winter. — Sides of the front of the head washed with 

 grayish brown ; sides of the back of the head and sides of the upper neck 

 black, more or less margined with ochraceous ; rest of the head, neck all 

 around, upper back, scapulars, and lower belly white; back, breast, and 

 upper belly black ; tail pointed, the middle feathers very long and narrow ; 

 band across the end of the bill yellowish orange. Ad. i in summer. — Sides 

 of the front of the head white ; crest of the head, neck, throat, breast, and 

 upper belly black ; back and scapulars black, the latter margined with dark 

 huffy ochraceous ; lower belly white ; tail and bill as in the preceding. 9 in 

 winter. — Upper parts black or fuscous; scapulars and upper back more or 

 less margined with grayish or grayish brown ; sides of the head and neck 

 and sometimes the back of the neck white or whitish ; breast grayish ; belly 

 white; tail pointed, but without the long feathers of the male; under wing- 

 coverts dark. Ad. 9 in summer. — Generally similar to the above, but the 

 sides of the head and throat mostly blackish, and the feathers of the upper 

 parts more or less margined with ochraceous. ' L., a , 21-00, 9 , 16-00 ; W., 8-60; 

 T., 3,8-00, 9,2-50; B., 1-0.5. 



Bemarlcs. — The male Old Squaw is too distinct to be confused with any 

 other species, its long tail-feathers being its most striking character; the 

 female bears some resemblance to the female of the Harlequin Duck, but has 

 the belly pure white instead of grayish dusky.
