THE GRASSHOPPER- WARBLER. 



Locustella ncevia (Bodd.). 



Owing to its comparative scarcity and somewhat skulking 

 habits this species was noted by comparatively few observers, 

 and its arrival and dispersion are consequently somewhat 

 difficult to trace. An immigration must have occurred about 

 the 16th o£ April, as records of single individuals were re- 

 ceived from Northamptonshire and Shropshire on the 17th, 

 and from Yorkshire on the 18th, while an increase in numbers 

 was observed in Northamptonshire on the latter date. The 

 arrival of the Grasshopper- Warbler on the south coast was 

 first recorded from the south-eastern counties of Kent and 

 Sussex on the 19th and 22nd respectively ; but although 

 that area seems to have been its chief point of entry, it 

 apparently arrived along the whole of the south coast. On 

 the 23rd it had reached Cheshire, and on the 28th it was 

 recorded from S. Wales. On the 1st of May there was 

 evidently a well-marked immigration, which probably con- 

 tinued during most of that week, along the whole of the south 

 coast, as the species was again recorded at the Hampshire 

 lights on the nights of the 3rd/4th and 4th/5th. The records 

 are too meagre to admit of any other movements being traced. 

 The first nest with eggs was observed in Devonshire on the 

 11th of May.
