84 THE BIRDS OF BERKS AND BUCKS. 



six feet from the ground, and I have found the nest 

 in a Hlac-bush, which is rather a frequent site. This 

 bird leaves us about the third week in September. 



Wood Warbler {^Sylvia sylvicold). Local names, 

 Wood Wren, Yellow Wren. A regular summer im- 

 migrant, but never appearing in such numbers as the 

 two following species. It arrives during the last week

 darkened by these markings that it is not easy to 

 distinguish the ground colouring.

Willow Warbler {Sylvia trochihis). Local name, 

 Yellow Wren. Arrives about the second week in
