78 THE SEDGE WARBLER. 



Its nest, which is generally composed of grass and moss 

 lined with hairs, and sometimes with the tops of umbelliferous 

 plants, is rather deep, and is usually placed in a low bush 

 or amongst tangled herbage. The eggs are four or five in 

 number, and of a pale yellowish brown, freckled all over 

 with a darker shade of brown. 



It is about the size of a Willow Wren, and may be dis- 

 tinguished from our other warblers of that size, by the 

 broad streak of yellowish white over its eyes, and by the 

 top of the head being streaked loogitudinally with dark 

 and light brown. 



The Reed Warbler {Acrocephalus streperus) has not been 

 observed in Berwickshire.
