This little Duck is exceedingly common in Northern and Central 

 India, less so in the South. It frequents both tanks and rivers, 

 and prefers grassy tanks and wooded jheels and rivers. It appears 

 to feed a good deal during the day, and is met with in large 

 parties scattered among the grass or w^eeds, the birds often rising 

 singly. 



This Pochard inhabits the same countries as the other species, 

 and is occasionally killed in Britain. It is stated to breed in 

 Northern Africa. One or two allied species are recorded from 

 Australia, and another from the Marianne islands.
