YELLOW-POLL WARBLER, 



This bird appears to have remained in obscurity 

 from its great similarity to the Yellow Willow 

 Warbler, and to the Pettychap Warbler, both 

 of which approach very near to this in size and 

 colour. It differs from the former in having the 

 plumage more vivid in colour, and in the belly 

 and under tail-coverts being pure white, whereas 

 in that bird they are tinged with yellow ; and from 

 the latter in its superior size: its manner and 

 habits are likewise different. 



It is found in Germany, where it is also migra- 

 tive.
