of niigraLlon on the south coast during September was the occurrence of 

 single birds at St. Catherine's Light (Lsle of AVight) on the 12th/ 13th 

 and 1.3th/14th. 



After mid-September there was apj^arently little movement on the 

 west coast. Small numbers were again recorded at light-stations on the 

 Welsh coast, the Isle of Man and Bristol Channel during the first ten 

 days of October and during the last few nights of that month and the 

 first days of November. This suggested a continuation of the September 

 movements, and there was nothing to show that the birds were of other 

 than British origin. 



At the beginning of the second week of October a very large move- 

 ment began on the east coast, and although no doubt a considerable 

 amount of southward "coasting " movement took place, there was also 

 ample evidence of direct passage across the North Sea ; the area of 

 arrival extended from Kent at least as far north as the Firth of 

 Forth. The first birds were noted at the Kentish Knock Light- 

 vessel on the 8th travelling W.N.W., and large numbers arrived on the 

 Norfolk coast on the 10th and at the Fame Islands and on the Yorlcshire, 

 Northumberland and Kent coasts during the four following days. After 

 the 13th fresh birds arrived almost daily at one or more points on the east 

 coast. At the Isle of May (Fife) the passage ceased on the 18th, but 

 was continued without intermission from S. Yorkshire to Kent until the 

 end of the first week in November. The only records after that date 

 were of single birds at Whitby Light on tlie llth/12th and 13th/l-lth 

 of November, so that it was clear all the birds had passed on. 



Migration along or from the south coast in October was divided into two 

 movements. The first, lasting from the 5th to the 10th, affected the coast 

 from Kent to the Isle of Wight and included the Channel Islands ; the 

 luimber of birds observed was large, and the records possibly represented 

 tlie emigration of the birds that had been passing south along the east 

 coast during the previous month. A single record from the south coast 

 of Cornwall on the 6th/7th may possibly in like manner have represented 

 the southward passage of some of the west coast migrants. T)ie second 

 movement began at Dungeness Light on the 20th, and corresponded with 

 the disappearance of the first lot of Continental migrants from E. Kent. 

 Birds were noticed in mid-Channel on the 22nd, and there could be no 

 doubt that many crossed the eastern half of the Channel direct during the 

 three following nights. Many, however, coasted to the west, as the light- 

 records form a continuous chain as far as the Scilly Isles : the southern- 

 most of these (St. Agnes) was reached by large numbers on the 1st of 

 November, the birds having been recorded en route at the Seven Stones 

 Light-vessel off the Cornish coast two nights previously. These birds 

 passed on south during the following days, while migration of quite small 

 numbers was still taking place from the Isle of "Wight during the same 

 period.
