The eggs of the Bulbul are ovate in shape ; texture smooth 

 and surface of a soft glossy appearance, which is so often 

 seen in the eggs of St/lvia simplex (Garden Warbler) and 

 Sylvia atricapilla (Blackcap). 



Colour. Looked at as a series the eggs do not vary very 

 much, but they divide themselves on examination into two 

 types. In type A the ground-colour is white ; in type B the 

 ground-colour is huffish. 



In most of the eggs the shell is rather well-marked with 

 spots, splashes, and streaks, both superficial and sub-surface ; 

 the former are of dark sepia and greenish dark brown, the 

 latter show through in faint grey. The markings are chiefly 

 found towards the obtuse end, in some very markedly. In 

 some of the eggs there is a strong tendency to zone in 

 colour.
