THE SEDGE-WARBLER {Acroceiyhalus 2Jhragmitis). 



The returns from our inland observers concerning this species were so 

 meagre tLat they give no definite information. The first movement 

 was indicated by the occurrence of a single bird at the Isle of May Light 

 (Fife) on the 15th of August and a few birds at Bardsey Light (Carnarvon) 

 on the 18th/19th, while a week later the returns from the south coast 

 lights clearly showed that emigration had begun. The records came from 

 the S. Foreland Light (Kent) on the 25th/26th and from St. Catherine's 

 Light (Isle of Wight) on that and the two following nights, the numbers 

 observed being, however, in each case quite small. During September 

 emigration was almost continuous between the 9th and 27th, being noted 

 at one or more of the lights along the south coast from the S. Foreland 

 in Kent to the Eddystone off Cornwall on the 9th/10th, nightly from the 

 12th to the 18th and froui the 20th to the 24th, as well as on the 

 26th/27th. Up to the loth the numbers Avere quite small, and it is clear 

 that the largest number of Sedge-Warblers left our shores between the 

 15th and 18th of September. 



From the west coast a few records were received from the light- 

 stations between Carnarvonshire and N. Devon ; the numbers in every 

 instance were, however, small and the movements represented were 

 probably of a coasting nature. Although returns were not received from 

 more than one station on a single night, it is perhaps of some significance 

 that the birds invariably arrived early in the night at the more northern 

 stations and considerably later at the more southern ones. In the 

 majority of cases these movements did not coincide with any recorded 

 movement from the south coast. The returns from the east coabt were 

 very scanty, a few Sedge-Warblers being noted at Withernsea Light 

 (Yorks) on September the 14th/15th and single birds on passage on the 

 S. coast of Yorkshire on the 20th, 24th and 25th.
