| Résumé : | Summary. 1 The main features of the first fifty years of British ringing are described. 2 Recovery rates are discussed. It is suggested that man's interest in a species is the most important determining factor. 3 A brief assessment is made of the contribution of British ringing to migration studies. 4 Some ringing projects are suggested. 5 Closer international co-operation is required to promote the reporting of recoveries. To this end propaganda campaigns and joint studies are advocated. 6 The number of separate ringing schemes in Europe causes difficulty in assembling data for extensive studies. |
