LEACH, HITHERTO in this series of articles we have thought it best to collect together all records of ringed birds, which have moved either from this country to abroad or from abroad to this country. This has meant a certain amount of duplication as the birds ringed here are also included in the lists of recoveries under the British ringing scheme. As the number of recoveries is constantly increasing it is now necessary to modify this plan and in this instalment we are omitting all records of birds ringed in the British Islands as nestlings or as breeding birds, but we shall continue to include those British-ringed birds which appear to be winter visitors or passage-migrants so as to give, with the records of those ringed abroad and recovered here, as complete an account as possible of the movements of these birds as shown by ringing. In the cases of the Starling and Black-headed and Common Gulls, as in our last instalment, we have summarized the records and omitted the detailed lists. The fresh records of these species are numerous, but do not materially affect the maps and summaries previously published. It should be mentioned that careful records of all unpublished cases are kept for reference in case they should be required. Reverting to the omission of the British-breeding birds it is to be hoped that when sufficient records have been accumulated each species will be fully dealt with as has been recently done in the case of the
