 yellow, tinged and speckled on breast with dark brown ; 

 under tail-coverts very long, yellowish-white, streaked with 

 dark brown ; bill dark brown above, yellow beneath ; feet 

 large, yellowish-brown. Length 5*30. Female: identical. 

 Distributed through England, Wales, the southern half 

 of Scotland, and in many Irish counties, but very local. 

 Nest : usually in a tussock of rank grass or among furze 

 and rank herbage on commons, the outskirts of copses, or 

 at the edge of a ditch ; composed of a quantity of dry 

 grass with a little moss, lined with fine grass. Eggs : 

 4 to 7 ; pale reddish-white, speckled all over with reddish- 

 brown, most thickly around larger end. Size "ji by '54. 

 First eggs laid about end of May ; there is a second 

 brood. Remarkable song is a clear, sustained trill, 

 resembling, at a distance, the continued sound of a tiny 

 bell ; it is always uttered when the bird is perched motion- 

 less in a small bush and is usually continued for about a 

 minute without a pause. Arrives at end of April, leaving 

 in September.
