The 1992 Suffolk Bird Report INTRODUCTION The systematic list of species has been written by the Editorial Committee, headed by the Editor, Mike Crewe, using data collated by the County Recorder, Philip Murphy and entered onto computer at the Ipswich Museum. The authors for each section are as follows: Divers to Shag : John Cawston Herons, Swans & Geese : Mike Crewe Ducks : Malcolm Wright Raptors, Gamebirds & Rails : Derek Moore Waders : Mike Crewe Skuas to Auks : John Cawston and Stuart Ling Near-Passerines : Stuart Ling Larks to Dunnock : Brian Small Chats and Thrushes : Rex Beecroft Warblers : Nigel Odin Tits to Sparrows : Brian Thompson Finches & Buntings : Rob Macklin Appendices : Mike Crewe The order and nomenclature follow the Birding World Complete List of The Birds of the Western Palearctic which in turn follows Dr K. H. Voous's List of Recent Holarctic Bird Species with any more recent alterations. All records refer to a single bird unless otherwise stated. Subspecies are listed under the main species heading, which includes the scientific name. With scarcer species, all records are listed under the parish followed by a more exact location, if known. The exception to this is at the river estuaries and larger, well-known sites criss-crossed by parish boundaries e.g Walberswick NNR, Minsmere, Orfordness, Alton Water etc. To minimise the threats to site security, some records of rare breeding birds are published anonymously and under a vague site heading. Unless otherwise stated, the tabulated sets of counts are the highest day counts for each locality, with each figure representing the maximum number of birds feeding or roosting at that particular site during the month; the bulk of these data comes from the Birds of Estuaries Enquiry (BoEE) co-ordinated counts. A dashed entry indicates that no figure was received. Counts from North Warren include Thorpeness Meare, Church Farm Marshes and the seashore between Thorpeness and Aldeburgh; the Aide/Ore includes the complex of the Aide, Ore and Butley rivers as well as Orfordness, Gedgrave Reservoir and Havergate Island; the Orwell includes Trimley Marshes, Bourne Park Water Meadows and Loompit Lake, Trimley St. Martin and the Stour includes the Essex side of the estuary. Where low-water counts are given they are generally carried out on the spring tide two weeks after the high-water count. We are in the fortunate position of having data for a number of years from a crosssection of geographically well spread sites throughout the County. It is to the credit of those observers who have persevered with such intense studies as the Common Bird Census (CBC), Constant Effort Site (CES) and transect counts, that this information is available for use. Such data are invaluable when monitoring any local population changes in common species. The centres of such activity lie at Dingle Hills, Westleton; Minsmere; North Warren, Aldeburgh; Belstead; Valley Farm, Coddenham; the Stour Valley (Cavendish to Long Melford); Newbourne Springs; Wolves Wood, Hadleigh/Aldham and Lackford Wildfowl Reserve. Fieldworkers involved in CBC, CES or other survey work are urged to forward summaries of their observations to the County Recorder at the end of the breeding season. Contributors are requested to be specific, especially when detailing observations of the commoner breeding species. 30
