IV. BRITISH BIRDS. 



their novel method of mapping out the haunts of selected 

 species was therefore a most welcome contribution, and 

 will serve as an invaluable model for further work. 

 Hand in hand with research of this kind is that of 

 marking birds, and considerable progress in this direction 

 has recently been made. There are great possibilities in 

 this method of tracing the movements and so on of 

 individual birds, and we hope to devote special attention 

 to it in the future. The subject of geographical races is 

 linked with these migratory movements, and we are glad 

 to note that a more general recognition of such races is 

 being made. Our heartiest support will always be 

 accorded to all w^ho are endeavouring to add to our 

 knowledge in this direction. 



Finally, we may refer to the articles on the additions 

 to our knowledge of British Birds recorded since 1899, 

 and now that these are complete, our readers Avill be 

 enabled to acquire an up-to-date knowledge of the subject 

 by ' consulting Howard Saunders' "Manual," and the 

 indices of the volumes of this Magazine. To keep these 

 records up-to-date month by month, with the help of our 

 contributors, and by reference to every contribution of 

 interest . published elsewhere, will be our constant 

 endeavour.
