southern counties, and from the 6th April onwards they 

 appear to have become settled in their breeding-quarters. 



The fourth immigration was much greater in extent than 

 the previous ones, and occurred along the whole coast from 

 Devon to Sussex on April 10th. A slight increase was 

 noted in the southern birds after this date, but the 

 majority of the ChifPchaffs in this movement seem to have 

 passed northwards, following the track of the first two 

 immigrations. 



The fifth immigration, which appears to have been the 

 largest and most extensive of all, arrived along the 

 whole of the south coast from Devon to Sussex between 

 the 21st and 25th of April. A first wave of this move- 

 ment struck the Devon and Hampshire coasts on the 

 20th and 21st, while a second and larger wave arrived in 

 Dorset and Hampshire on the 25th, but the birds were 

 coming in along the coast from the 20th to the 25th 

 inclusive. They swept rapidly northwards through Wales 

 into the Isle of Man and the northern counties of England, 

 and this immigration seems to have supplied the resident 

 birds of the Midlands, Wales, and the North. 



There is a certain amount of evidence pointing to the 

 occurrence of another immigration in Hampshire and 

 Sussex on May the 3rd, but at that date Chiffchaffs were 

 so numerous throughout the country that it is not possible 

 to trace this supposed movement with any certainty. 



It is worthy of note that only five individuals of this 

 species struck the Lights, although on at least one occasion, 

 viz., April 9th and 10th, they were migrating at a time 

 when the Lights proved an attraction to many other 

 species. The Willow- Warbler, in particular, struck the 

 Lights in great numbers on April 9th, 10th and 11th.
