 blotched with dark olive and grey. 



MARSH WARBLER (Acrocephalus palustris).

 It breeds in Somersetshire, Gloucestershire, and Oxon, 

 and, no doubt, in other suitable counties.

 less rufous and greener on upper parts. Wing-feathers 

 tipped and edged with pale buff, under parts yellower, 

 and legs pale brown. Length 5 J in.

 It is also a mimic, and sings at night.

Site. Never overhanging water like last. In low 

 bushes, meadowsweet, or nettles, near water. 



Materials. Grass, moss, and leaves, lined with 

 horsehair ; cup deep, but not so deep as last. 



Eggs. Five to seven. Whiter ground-colour than 

 last ; spotted and blotched olive-brown and grey.
