THE SCAUP DUCKS. 



The Scaup Ducks differ from the Pochards 

 in the pattern of the primaries and in 

 having a much broader bill. The bill 

 is also rather wider near the tip than 

 at the base. 



The two Indian species of Scaup 

 Ducks resemble each other rather closely. 

 The Tufted Duck at all ages, however, 

 has a pointed crest, short in females and 

 young birds, long in the adult males. 

 In the bill of this species the tip is black 

 as well as the nail. The Scaup has no 

 sign of a crest, and only the nail of the 

 bill is black. 



It is well to mention that in the Scaup 

 Duck the speculum is always much wider 

 than in the Tufted Duck, and the black 

 of the breast reaches down much further. 

 These characters, however, are compara- 

 tive and not of much practical value, 

 unless specimens of the two species are 

 laid side by side. 



Adult males of the two species differ con-
