200 BRITISH BIRDS. 



and have proved of great value for reference purposes ; most 

 unfortunately the form of this " Report " has been altered, 

 and the records and information are arranged under headings 

 such as, ^ew Birds to Scotland or Fauna! Areas, Summer 

 and Winter Notes, Migration, etc. For reference this form 

 is practically useless, since, to discover what has been recorded 

 of one species during the year, one has to read through some 

 thirty closely-printed pages ; and even if time can be found 

 for this, there is a great risk of missing the bird one is looking 

 for. This is especially evident in the migration notes which 

 are arranged chronologically. To group the information 

 under the headings of species is the only way to make a Report 

 of this kind really useful, and we sincerely hope that the 

 present plan will not be continued. 



The following records are either new, or have not been 

 previous! V referred to in our pages. All the dates are in 

 1910 :— ^

in spring at Fair Isle, and one seen Scarnish, Tiree,
