136 ANSERES ANAS 



Layard states that this Duck nests on the dry veld away from 

 water in dense bush, and that, as the female sits very close, she is 

 difficult to find. Ayres, on the other hand, states that the nest is 

 built up of dry flags among the rushes, well above the level of the 

 water. 



The .eggs, generally from six to nine in number, are elliptical, 

 smooth, and vary from a very pale brown to creamy in colour; 

 examples from Zoetendal's vlei in the South African Museum 

 measure 2-27 X 1'75.
