Abstract
This study of the results of ringing Razorbills in Britain brings further evidence of the wealth of information that can be drawn from the Bird Ringing Scheme-even when the recovery rate is as low as 3070. Records are grouped by age-classes and distance from the ringing site, and illustrate a migratory tendency in younger birds but a random dispersive movement for those of three years' old and more.
