372 Manual of the Game Birds of Ittdia. 



The Long-tailed Duck {Harelda 

 glacialis). — It occurs throughout a con- 

 siderable portion of Northern and Central 

 Asia, and has been obtained on the Caspian 

 Sea and in China. It may therefore 

 straggle into India. In the pattern of the 

 primaries and in the colour of the axillaries 

 it resembles the Golden-eye, but no portion 

 of the quills of the wing is white. These 

 characters will suffice to separate the 

 Long-tailed Duck from the Golden-eye 

 and all other Indian Ducks, at all ages. 

 The adult male has a large portion of 

 the plumage white ; and the central tail- 

 feathers are greatly lengthened. The 

 female has the plumage of a dull brown 

 colour and the middle tail-feathers are 

 not lengthened.
