THE SEDGE-WAEBLEE. 



Acrocephalus phragmiiis (Bechst.) 



Like a good many other species, the Sedge-Warbler 

 appears to migrate in small parties, and hy the nature of 

 its habits the bird may easily be overlooked for a day or 

 two after its arrival. In consequence, it has been a 

 difficult task to obtain from the records received a good 

 idea of the way by which the species arrives in this 

 country and disperses through it. 



The first arrivals appear to have come to land in Devon 

 and Hampshire on April 11th and 12th, and thence to 

 have spread north into Berkshire (llth), Somerset (I3th), 

 Bedford (15th), Staffordshire and Cheshire (16th), and 

 Anglesea (I8th). 



The next distinct immigration was noted further to the 

 eastward in Sussex, firstly on April 20th, when a few 

 birds were recorded, and more markedly on the following 

 day, when a considerable number were observed. 



As a result of this immigration, the Sedge- Warbler 

 spread into Norfolk in considerable numbers on April 21st, 

 and was recorded from Kent and Essex on the 22nd, 

 Surrey on the 24th, while it had reached Yorkshire by 

 the 26th and Durham by May 1st. 



On April 27th and 28th an immigration was noted on 

 the Hampshire coast. These birds appear to have spread 

 inland into Dorset and Hampshire, while some seem to 

 have taken a north-westerly route, as the species is 

 recorded from Lancashire on April 30th and from Shrop- 

 shire on May 1st, while an increase is noticeable in 

 Anglesea on May 2nd. 



A further arrival seems to have taken place in Hamp-
