PREFACE. 



The thirtj-seconJ volume of the British Ornitliologists' Ckib 

 contains the Report of our Mio-ration Committee on the 

 movements in Enoland and Wales of a number of common 

 migratory species during the autumn of 1911 and the 

 spring and early summer of 1912, A slight change has 

 been made in the arrangement of the Weather-Report 

 (pp. 13-31) ; the species occurring day by day being placed 

 at the head of the right-hand column instead of in the 

 column to the left beneath the date ; by this means a con- 

 siderable saving in space has been etfected, but the Report 

 is nevertheless slightly longer than that of the previous 

 year. 



The winter of 1911-12 was chiefly remarkable for the 

 great invasion of Little Auks, many hundreds of which, 

 having been driven southwards, were blown inland by gales 

 and perished in all parts of the country. 



The Members of our Migration ('onnnittee are jointly 

 responsible for the following Report.
