Spot-billed duck has been considered as a rare
migrant till recent time. But Ceylon
Bird Club members were able to observe some breeding birds of this duck in
Vankalai Ramsar wetland site recently and so it is now considered as a Breeding resident
of Sri Lanka supplemented by migrant birds from India during the North-East
monsoons .Migrant birds are earlier reported from tanks, paddy fields and
marshes of Jaffna peninsula, Mahawelli flood plain national park and eastern sea
belt. This duck can be distinguished from all other ducks by its colorful bill.
Vankalei is a good site for observing this duck and above picture was taken
while it was flying over the Mannar causeway.
