THE REED-WARBLER 



Acrocephalus streperus (VieilL). 



The movements o£ this species were difficult to trace owing 

 to the scanty nature of the records, and also to the fact that 

 the early immigrants were not observed at any of the lights. 

 The first arrivals recorded were in Kent and Somersetshire 

 on the 22nd of April, and from that date to the end of the 

 month stragglers occurred in various counties, a solitary bird 

 reaching Cumberland on the 26th. 



These birds probably slipped unobserved into the country 

 in the great wave of immigration of many species that arrived 

 on our south coast on the night of 22nd/23rd of April. 



The increase in the various counties during the first week 

 in May appears to have been due to an arrival ou the eastern 

 and south-eastern coasts ; these arrivals apparently extended 

 westward and northward during the next ten days, but no 

 very satisfactory conclusion can be drawn from the data to 

 hand. On the night of the 26th/27th of May several were 

 seen and two killed at St. Catherine's light (Hants), but that 

 was the only record received from a lighthouse relating to this 

 species. A nest ready for eggs was found in Berkshire on 

 the 15th of May.
