The Results of Ringing Auks in Britain and Ireland

The movements of British auks, as revealed by ringing, are highly complex, and the detailed analysis undertaken here reveals that different age-groups, and different local populations, within a species are often exposed to different risks during the non-breeding season. Any conservation measures must, therefore, depend heavily on ringing results. International action to prevent oil pollution would benefit all populations, and the outlook for many British colonies would be improved if shooting for sport in areas as distant as the Norwegian, French and Iberian coasts could be banned.
