This bird was one of a small flock on the lake. The 
birds were very shy and difficult to approach ; after being 
hit the bird dived down in the water, and tried to hide 
between the submersed waterplants *. The natives living 
round the lake did not know this species of duck, which 
proves, that it is not a common visitor there.
