THE SEDGE-WARBLER. 



Acrocephalus phracjmitis (Bechst.). 



The Sedge- Warbler arrived along the whole of the south 

 coast, but chiefly on the eastern half. 



The first arrivals recorded were iwo birds in Somersetshire 

 on the 7th o£ April. A few other stragglers appeared be- 

 tween that date and the 14th, and were followed by slightly 

 larger numbers in Hampshire and Kent on the 15th, and in 

 Dorset on the 17th. Further smaller immigrations occurred 

 on the south coast as far west as the Eddystone between the 

 20th and 22nd, at the Isles of Scilly on the 26th, and in 

 Dorsetshire on the 29th, so that by the end of the month 

 Sedge-Warblers were thinly but evenly distributed over the 

 whole country. They reached Yorkshire by the 21st and 

 (.'Umberland on the 2oth, while arrivals were recorded in 

 the Clyde area by the 1st and 2nd of May. 



In the latter half of the first week of May a larger immi- 

 gration took place along the whole oP the south coast, and was 

 followed by another during the second week of the month, both 

 of these movements being recorded in the Channel Islands. 

 The first of these seems to have compri:;ed both passaoe- 

 migrants and our own summer-residents, more particularly 

 those of the midlands, northern counties and Scotland, 

 while the second seems to have consisted mainly of passage- 

 migrants. The presence of the latter in both movements i^ 

 shown by the occurrences at lights on the west and more 

 particularly on the east coast, as well as by the records from 

 the Pentland Skerries. These passage-movements continued 

 until the middle of the third week in May. In the mean- 

 while the earlier arrivals lost but little time in settlino- down,
