332 BRITISH BIBBS' NESTS. 



It does not breed iu the extreme western peninsula 

 of England, and is rare in the northern counties. 

 It is not known to breed in Scotland or in Ireland, 

 and is said to be somewhat rare in Wales. 



Materials. — Long blades of dried grass, seed- 

 branches of reeds, roots, dry leaves, and wool, lined 

 with fine grass and hairs. The nest is very deep, 

 a necessity occasioned by its supports being swayed 

 to and fro by gusts of wind. 



Eggs. — Four to five, dull greenish-white, greyish- 

 green, or pale greenish-blue, spotted, blotched, and 

 blurred with darker greyish-green and light brown. 

 A few black spots or streaks of dark brown are 

 sometimes j^resent. They are variable, both in the 

 tint of the ground colour and markings. Size about 

 •74 by '53 in. Their darker ground colour and the 

 situation of the nest distinguish them from the eggs 

 of the Marsh Warbler. 



Time. — End of May, June, and even at the 

 beginning of July eggs may be found. 



Ilemarhs. — Migratory, arriving in April and May 

 and leaving in September. Notes : varied, loud, and 

 hurriedly delivered. Naumann represents them as 

 tiri, tier, zdcJi, zerr, scJierl-, Jieid, tret, each note 

 being repeated a number of times. Local and other 

 names : Night Warbler, Eeed Wren. Sits rather 

 closely, and is noisy when disturbed.

 country, but has long since ceased to do so on 

 account of the drainage carried out therein, and 

 is now only a very rare summer visitor.
