SEDGE WARBLER. 85 



Mr. Heysham mentions a nest which contained three 

 quite white. Sometimes they are uniform dull yellow: 

 they are laid early in May. 



One variety consists chiefly of pale olive brown, 

 with a thin waved streak at the thicker end. 



A second is grounded with very pale yellowish 

 green, with one very thin waved black streak at the 

 thick end. 



A third is of a greyish colour, thickly mottled all 

 over with green. 



The above are figured by Professor Thieneman.
