Résumé :	Rare seabirds are often extremely hard to identify, and a significant part of the problem is that, when observed from land, circumstances are typically very difficult. In many cases, one or more of the following drawbacks applies: the weather conditions are poor, views are distant and brief, and photographic evidence is impossible. For these same reasons, records of rare seabirds are also difficult to assess, particularly so if they concern what would be a 'first for Britain' for the species in question. This was the case when a probable Herald Petrel Pterodroma arminjoniana was seen off Dungeness, Kent, in January 1998. In this paper, the circumstances and the assessment of that record are described, and, more generally, the level of supporting evidence which is necessary for acceptance of records of rare seabirds is discussed.
