BONELLl's WAEBLER. 47 



may be easily found in dry grass meadows. It is es- 

 pecially partial to tall thick ferns, as well as long grass. 



Mallierbe's statement that it builds in poplars and 

 other thickly-foliaged trees, is, I think with good reason, 

 denied by Count Miihle, as being quite diiferent to the 

 habits of other Wood Warblers. 



Thienemann says the nests are woven and bound 

 together with dry twigs, intermixed with Acinos vul- 

 garis, and lined with dry grasses, moss, and oak leaves, 

 the entrance wide open. It contains four or five eggs, 

 the ground colour in most of which inclines to brownish; 

 they are also a brownish grey and a reddish brown, 

 delicately spotted, and in many specimens forming a 

 wreath round the greater end. 



Brehm, in Badeker's magnificent work upon the Eggs

 overgrown with plants, by which the nest is concealed, 

 the stalks and blades of the growing grass being inter- 

 woven with the nest. The eggs are of a white ground, 

 with small brown-red spots and dots thickly scattered, 

 and of light or darker coloiu*, wreathing like that of 

 S. sibilatrix.^'' 



Temminck's account differs little from? this. 



Degland says the "Pouillot Bonelli nests in the 

 ground in the middle of the grass, or at the bottom of 

 underwood; its nest is similar to that of 8. sihilatrix, 

 and it contains from four to six eggs — short, white or 

 reddish white, with reddish brown spots very numerous, 

 and thickly scattered, especially at the larger end. Long- 

 diameter fifteen, shorter twelve millemetres." 



The adult male has the head, nape, and upper part 

 of the back bright yellowish olive green; the wing feathers
