THE SEDGE-WARBLER. 



Acrocephalus pliragmitis (Bechst.). 



The records from the counties along the south coast were 

 somewhat scanty, so that it is difficult to make any very 

 definite statement as to the points of entry of this species, but 

 it apparently arrived along the whole of the southern coast- 

 line. The first arrival noted was in Kent on the 2nd of 

 April, after which there were no further records until the 16th, 

 when arrivals were reported in Hampshire, Somerset and 

 Herefordshire. The usual numbers of breeding-birds were 

 said to have arrived in the last-named county by the 21st, and 

 by the end of the month the species was scattered sparingly 

 over the country as far north as Yorkshire. 



Between the 1st and the 6th of May there was a considerable 

 influx of Sedge-Warblers, and large numbers were observed 

 passing St. Catherine's and Duugeness lights on several 

 nights. An extension northward took place towards the 

 middle of the month, stragglers arriving in the Clyde area 

 on the 10th and in Lancashire and Cumberland on the 11th, 

 while there was an increase in the number of birds in both 

 the latter counties on the 16th. Migratory movements 

 continued (though on a smaller scale) up to the end of the 

 month, and even later, as numbers of birds were seen passing 

 Bardsey light on the night of the 2nd/3rd of June. 



A nest was found in Radnor on the 22nd of May, and nests 

 M'ith eggs in Derbyshire on the 27th, in Suffolk on the 28th 

 and in Hertfordshire on the 29th.
