 considerable numbers was also noticed in Staffordshire from 

 the 21st to the 27th of April, in Somersetshire on the 12th of 

 May, and at various dates towards the end of April on the 

 Suffolk coast. The fluctuation in numbers in inland localities 

 until nearly the end of the third week in May would seem to 

 indicate that passage-movements were also in progress over 

 a large part of the country. 



While migration was still in progress, the earlier immi- 

 grants had begun to breed. Nesting-operations were reported 

 in Berkshire and Breconshire on the 28th of April, in Surrey 

 on the 1st of May, in Devonshire on the Gth, in Cambridge- 

 shire on the 11 th and in Renfrewshire on the 12th, while 

 eggs were found in Staffordshire on the 18th and in Somer- 

 setshire on the 22nd.
