are white, frequently with a buff tinge. 

 The primaries and their coverts are black. 

 The outer secondaries are metallic green 

 or coppery bronze on the outer, largely 

 white on the inner, web. The remaining 

 longer secondaries are chestnut on the 

 outer, more or less ashy on the inner, web. 



The adult male has a narrow black ring 

 round the neck during the breeding season, 

 and this ring is often present on birds 

 when they first arrive in India in October, 

 but is soon lost. It is resumed again 

 before leaving in March. 



The adult female resembles the adult 

 male, but never assumes the black ring 

 round the neck. The front part of the 

 head often, but not always, is paler than 

 in the male. The feathers of the chestnut 

 parts of the plumage usually have pale tips. 



Ducklings, after changing from the 

 down plumage, resemble the adult female ; 

 but the scapulars, the upper back and 

 the inner secondaries are brown, vermicu- 

 lated with rufous. The tail is indistinctly 

 barred with rufous and tipped with buff. 



Male : length about 26 ; wing 15 ; tail 

 6. Female : length about 23 ; wing 14 ; 

 tail 5|. The bill is black ; irides dark 

 brown ; legs and feet very dark brown. 

 ^Veight up to about 4^ lb.
