ing Scotland and Yorkshire in numbers on the 10th ; with 

 these birds also those, which had remained in Cheshire as 

 the result of the first immigration, appear to have passed on. 



The third immigration, which was not a large one, was 

 noticed in Hampshire on April 8th and in West Sussex 

 on the 9th and 10th. The birds in this movement appear 

 to have spread into Berkshire, Essex, Norfolk, and possibly 

 Yorkshire during the following few days. 



Part of the birds composing the above three immigra- 

 tions formed the breeding-stock of the southern counties. 



The fourth immigration was confined to the w^est. The 

 birds arrived in Devon on April 11th and spread quickly 

 northwards, numbers being recorded from Cardigan on 

 the 12th, Staffordshire on the 13th, Radnor on the 14th, 

 while some reached Anglesea and the Isle of Man on the 

 15th, Yorkshire on the 16th, Cumberland on the 17th, and 

 Durham on the 19th. 



The ffth immigration took place in Devon on April 

 14th and in Hampshire on the 15th, while further 

 arrivals, which may be taken as part of the same move- 

 ment, occurred in the same counties on April 17th. A 

 portion of these immigrants appears to have travelled into 

 Shropshire and Cheshire on the 16th, Merioneth on the 

 18th, and to have left the country on the 19th. Another 

 body seems to have reinforced the birds in Essex on the 

 19th, and then to have disappeared (probably northwards) 

 with a large number of those which had been noted in 

 Essex for a fortnight previously. 



There are indications of further immigrations of this 

 species, but the records do not allow of their being traced 

 successfully.
