THE ^^'ILI-OW-WARBLER (Phjlloscopus trochilm). 



The southward movement began early in August, for during the first 

 fortnight the local birds were leaving Mull (Argyll), and an observer in 

 Cumberland reported the arrival of small flocks of Willow- Warblers on 

 the 3rd ; between the 7th and 21st a decrease in their numbers was 

 noted in Northumberland, Warwickshire and Staffordshire, while a 

 passing increase was observed in Shropshire. During this period 

 numbers arrived and passed on through Kent and Sussex, a further 

 passing movement being noted in the former county between the 25th 

 and the 28th. On the 20tli one was taken at the Bass Eock Light 

 (Haddington), and others occurred there on the following day. 



During the first half of September Willow-Warblers were passing 

 through Somerset and Devonshire in some numbers. On the nights of 

 the 14th/15th, 15th/16th, 16th/17th and 17th/18th great numbers of 

 migrants were noted at the lights at Bardsey (Carnarvon), Flatholm 

 (Glamorgan), Anvil Point (Dorset) and St. Catherine's (Isle of Wight). 



In Yorkshire (both on the south coast as well as in the south-west of 

 the county) marked waves of migration took place between the 18th and 

 26th, during which period birds were also noted as passing through 

 Surrey. A decrease in Sussex was observed on the 26th, on which date 

 a good many were reported from the Isle of May, but these passed on 

 two days later. 



Stragglers were recorded in the counties of Warwickshire, Somerset 

 and Dorset during the first half of October, and one was observed on 

 the Isle of May as late as the 18th. 



Among a large arrival of Willow- Warblers on the south coast of 

 Yorkshii-e on the 24th of September there occurred one specimen at least 

 of the northern form, P. trochihis cvers^nanni.

At least ten different individuals were noted on the Isle of May 

 (Fife) ; single birds were seen on September 16th, 24th, 25th and 30th 

 and on October the 24th, while two were seen on September 26th and 

 28th and three on October the 27th. Single birds were also recorded 

 from the east Ross-shire coast on September 23rd and 27th, four from 

 Fair Isle between the 28th of October and the 4th of November, and one 

 was shot on the north coast of Lincolnshire on October the 12th.
