THE SEDGE- WARBLER. 



Acrocephalus pltragmitis (Bechst.). 



The Sedge- Warbler was first recorded on the 6th of April, 

 when a small number appeared on the southern coast o£ Kent. 

 This arrival may have accounted for single individuals which 

 were noted in Bedfordshire and Cheshire on the 10th and 

 11th of April. 



The first regular immigration was a small one observed on 

 the 13th and 14th of April on the eastern parts of the south 

 coast, from Hampshire to Essex. 



This movement was followed by a large influx on the 17th, 

 18th, 19th and 20th of April, along the south coast, from 

 the Isle of Wight to Essex, hundreds being seen and twenty 

 killed at St. Catherine's light. Isle of Wight, early on the 

 morning of the 17th. The only records from the west were 

 those of a single bird seen in Cornwall on the 12th and of 

 two in Dorset on the 20th of April. 



A second large immigration took place along the eastern 

 part of the south coast, from the Isle of Wight to the 

 northern border of Essex on the 22nd, 23rd and 24th of 

 April. Meanwhile the birds which had already arrived had 

 spread over the greater part of England. 



From the 25th of April to the 2nd of May there seems 

 to have been little, if any, further immigration on the 

 south coast ; during that period the individuals of the second 

 large immigration appear to have spread over the country, 

 Yorkshire and Lancashire being reached on the 25th and 

 26th of April, Durham and Cumberland on the 1st of May, 

 while a single bird was recorded from the Isle of Man on 

 the 2nd. Meanwhile the southern counties showed a corre- 

 sponding decrease.
