THE aEASSHOPPEE-WARBLER. 



Locustella ncBvia (Bodd.) 



The immigrations of this species are diificult to trace as 

 the number of records is very small, owing presumably to 

 the skulking habits of the bird and its local distribution. 

 It apparently arrived in small numbers, and as far as 

 can be made out it first reached this country along the 

 south coast from Dorset to East Sussex. 



The earliest arrival took place on the 9th April. The 

 birds quickly moving on to their summer-quarters, and 

 spreading north, reached the Norfolk Broads by the 15th, 

 Cheshire on the 22nd and Durham on the 24th. 



The only immigration in any numbers took place at 

 Swanage in Dorset, on the 26th April, the day after the 

 occurrence of a large immigration of Chiffchaffs, Willow- 

 Warblers, Wheatears and Swallows. This immigration was 

 apparently continued on the following night when it was 

 recorded from the St. Catherine's Light in the Isle of 

 Wight. The further j)i'Ogi"ess of this movement is not 

 easy to trace, but it apparently continued northwards, 

 reaching Somerset on the 28th, Shropshire on the 29th 

 and Yorkshire on May 1st. As far as can be gathered 

 from the records of the spring of 1905 it seems probable 

 that the Grasshopper- Warbler arrives in this country on 

 the coasts of Dorset, Hampshire and Sussex, and that it 

 at once disperses to its breeding-quarters throug-hout 

 the country where it remains without further migratory 

 movement.
