 The drake does not leave his mate after the eggs have all been laid, 

 but assists in incubation and in protecting the young. The nest is 

 a slight hollow in the ground with down for lining ; the eggs are 

 pale huffish green in colour.

 water, and is hence able to feed in deep as well as shallow seas 

 at a distance from land.
