western half o£ the .south coast between the 1st and 3rd 

 of April, but its effect cannot be traced for any great 

 distance. 



On the 5th of April a very extensive movement began with an 

 arrival at the eastern end of the south coast, followed by one 

 in the west two days later. This migration, which seems to 

 have contained the bulk of our nesting-birds, was continued 

 without intermission in the west and at intervals in the 

 east up to the 15th. The arrival of some numbers in 

 the west on the 17th of April may be regarded as the 

 continuation of this extensive movement, and migration 

 was also recorded at Hanois light (Guernsey) during 

 the previous night. With the arrival of these birds the 

 Chiffchaff's distribution was quickly completed, and the usual 

 numbers were reported from Cornwall on the 14th, Devon- 

 shire, Worcestershire and Cheshire on the 15th, and Berkshire, 

 Carmarthen, Suffolk and Carnarvon on the 22nd. Nesting- 

 was reported from Devonshire on the 15th, from Berkshire and 

 Shropshire by the 19th, and from Wiltshire on the 21st, 

 while eggs were found in Somerset on the 25th, and in 

 Dorsetshire and Lincolnshire on the 4th and 8th of May. 



There seem to have been further small immigrations on 

 the 20th and 30th of April and the 4th and 6th of May, 

 chiefly on the eastern half of the south coast, but their 

 progress through the country cannot be traced.
