 and in small numbers on the nights o£ the 13th, 14th 

 and 19th ; there were also indications that arrivals took 

 place on the south coast until the 13th, and that passage- 

 movements were in progress up the west coast during the 

 same period. It seems probable also that some of the 

 residents for our northern counties were included in the 

 earlier part of this movement, but owing to the number of 

 birds already present in the country their progress could not 

 be traced until their presence became manifest in their 

 summer-quarters. The greater proportion of these birds 

 must, however, have been passage-migrants on their way to 

 more northern summer-quarters. 



Whitethroats were recorded as nesting in Devonshire on 

 the 25th of April. Nests ready for eggs were found in 

 Somersetshire on the 3rd of May and in Cheshire on the 5th; 

 on the 4th eggs were found in Hertfordshire and the species 

 was reported to be nesting in Berkshire, Essex and Stafford- 

 shire. Eggs were also found in Cambridgeshire on the 6th, 

 in Hampshire on the 10th, in Gloucestershire on the 14th, 

 in Shropshire and Lancashire on the 15th, in Surrey and 

 Yorkshire on the 17th, and in Derbyshire on the 18th.
