THE AVILLOA\'-AVAKBLER. 



I'hilUosL'opas trochUus (L.). 



DiRiXG tlic last Aveek of March stragglers Avere recorded 

 along the Avliole of the south coast, and inland I'rom Hertford, 

 Brecknock, Warwick and Leicester. 



On the 3rd of April a fairly large flight was reported from 

 the Eddystone light, and the birds ajipear to have scattered 

 into many counties, Yorkshire being reached on the 5th. 



On the 7th a small flight was noted at the Hants light, while 

 on the same day there was a marked increase in Somerset 

 and on the 8th in Yorkshire, but these birds do not seem to 

 have remained. 



Apparently the main body of this species began to arrive 

 on April the 1 Itb, for on that night hundreds were noted at 

 St. Catherine's light, Hants, while small flights were seen on 

 the 12th at the Eddystone light, Cornwall, and again at 

 St. Catherine's on the 12th and 13th. A laroer flipht was 

 observed at the Start light, Devon, on the 14:th. These birds 

 apparently helped to augment the numbers in the southern 

 counties. This innnigration reached its height on the 15th, 

 when vast numbers of Willow-Warblers, in company with 

 other species, reached the southern coast between C.ornwall 

 and Hants. The light-keeper at St. Catherine^s reported that 

 " Willow-Warblers were the most })lentiful, and were rest- 

 ing everywhere about the lantern." On that night no less 

 than 78 were killed at three lighthouses, viz. at the Eddy- 

 stone, Portland Bill and St. Catherine's. 



This immigration continued on the night of the IGth, as is 

 shown by the returns from the St. Catherine's and Eddystone
