Nest. A floating mass of weeds. The one discovered by 

 Mr. Robert Read in Renfrewshire, in 1889, was built, he tells 

 me, " amongst the rank herbage of a floating island, although 

 the nest was not actually in the water like that of a Little 

 Grebe. It contained three eggs, and, though they were about 

 a week incubated, they were not covered up." 



Eggs. Three or four in number. Greenish- white, with a 

 chalky covering, but as incubation proceeds they become 

 stained, through contact with the decomposing weeds of which 

 the nest is made, an ochreous or brown colour. Axis, 2 '1-2 '45 

 inches; diam., 1-4-1-55.
