Clarke) published no returns from the lighthouses on the 

 south coast of England, and had no system of inland 

 observers whereby the movements of the migrants through 

 the country could be traced. 



It was in order to supply this lack of information that 

 we were appointed by the B.O.C., and in this first year of 

 our work we have confined our attention solely to the 

 migratory movements in the spring of 1905 of twenty-nine 

 species of summer- visitors to these islands. Our observers, 

 however, have recorded notes of the arrival and departure 

 of other species, and these observations we have tabulated 

 at the end of the Report. 



The following is a list of the species with which our 

 Report primarily deals : —

 Willow- Warbler 

 Wood-Warbler 

 Reed- Warbler 

 Sedge-Warbler

We have endeavoured in the following pages to trace, by 

 means of the records both from the land-observers and 

 from the light-keepers, when and where these birds entered 

 the country, how they dispersed themselves over it, when 

 they reached their breeding-places, and, finally, how some 

 of them passed through, and out of, the country. 



It cannot be too strongly urged that the results arrived 

 at in any one year of such an enquiry, by whatever means 

 it may be carried out, can only be regarded as approximate, 

 and may even, in some cases, be altogether abnormal. 

 Should the enquiry, however, be conducted for the space of 

 several years, we feel confident that it would yield a very
