THE SEDGE WARBLER 
with dark brown lines and scratches. ‘The nest is only 
discovered with difficulty, and, as is usual with so many 
Warblers, the sitting bird slips off in a very stealthy manner 
when disturbed. 
The adult Sedge Warbler is russet-brown above, each 
feather with a dark brown centre, very pronounced on 
the head and wings, and absent from the rump, which is 
of a more rufous tinge. The eye-stripe is pale buff ; the 
under parts are pale buff, darkest on the breast and flanks. 
Bill dark brown above, paler below ; tarsi and toes pale 
brown ; irides brown. Length 4? inches.
