PEEFACE. 



The thirtieili volume ot" the British Ornithologists' Club 

 contains the Report of: our Migration Committee on the 

 movements in England and Wales o£ a number of common 

 migratory species during the autumn o£ 1910 and the 

 spring and early summer of 1911. It differs but little from 

 those already published. In spite of the efforts which 

 have been made to condense the matter contained in the 

 autumn-records, it exceeds the last Report by many pages. 



The Members of our Migration Committee are jointly 

 responsible for the following Report.
