Population studies of the Fulmar on Eynhallow, Orkney Islands

This short paper describes the background, initiation and development of what has turned out to be a long-term (41 years to date) study of Fulmars on Eynhallow in Orkney. Most of the scientific results have been published (see Appendix 1) so that only the major findings will be referred to here, to illustrate how the study has evolved as knowledge increased, new techniques became available and objectives changed.
