known it destroyed by being trampled on by sheep 
or other stock. 
The Willow Warbler very much resembles the 
Chiffchaff, and has often been mistaken for it; but 
it may be easily known from that bird by the colour 
of the legs, which in this species are a light flesh-

under mandible pale yellow, brown at the base; 
irides hazel; the head, neck, back, scapulars and 
tail-coverts darkish olive-green; wing-coverts and

on the outer web; the tail-feathers are also margined

breast, flanks, belly and under tail-coverts dull white, 
tinged with yellow—there is a darker shade in the
