Résumé :	For this fourth annual report, covering 1998, information on assessed and accepted records of scarce migrant birds was supplied, sometimes in advance of publication in their local bird reports, by County Bird Recorders. There were all-time record numbers of two species in 1998: Cory's Shearwater Calonectris diomedea and White Stork Ciconia ciconia. Furthermore, Balearic Shearwater Puffinus mauretanicus, Wryneck Jynx torquilla, Horned Lark Eremophila alpestris and Great Grey Shrike Lanius excubitor each registered the highest totals since we started to monitor their occurrences annually; and numbers of Purple Herons Ardea purpurea and Red-backed Shrikes Lanius collurio in 1998 were the joint-highest and highest respectively during the last ten years. In 1998, no species registered its lowest-ever annual total, nor was any species' annual total the lowest during its study period. Fewer Tawny Pipits Anthus campestris, Savi's Warblers Locustella luscinioides, Aquatic Warblers Acrocephalus paludicola and Melodious Warblers Hippolais polyglotta were seen in 1998, however, than in any other of the last ten years.
