THE nest of this common winter visitant is large a mass 

 of reeds, sedges, and other water-plants, placed by the 

 edge of the liquid element, or floated on the surface among 

 the rushes or other such vegetation that there has its natural 

 growth. 



The eggs appear to be from two to four in number. 

 They are of a white colour, with a faint tinge of blue when 

 first laid, but they soon become stained.
