The 2009 Suffolk Bird Report Systematic List roduction e list and its appendices have been written using data supplied by the county's dwatchers and conservation organisations. The raw data have been collated and rpreted by the following:ans and geese :cks me birds, rails to Crane ers to Spoonbill ntors tercatcher to Ruff pes to phalaropes iias to gulls

The 'official' British list is maintained by the British Ornithologists' Union (BOU). ecies are included in various categories according to their status, as follows: Category A - species which have been recorded in an apparently natural state at least once since January 1st 1950; Category B - species that would otherwise be in Category A but have not been recorded since December 31st 1949; Category C - species that, although originally introduced by man, either deliberately or accidentally, have established self-sustaining breeding populations; Category D - species that would otherwise appear in Categories A or B except that there is doubt that they have ever occurred in a natural state; ategory E - species that have been recorded as introductions, transportées or escapees from captivity, and whose breeding populations are not thought to be self-sustaining. I he main part of the species accounts consists of species that occurred in Suffolk in 2009, ich fall into Categories A and C. Where a species is included in multiple categories, this îown in the initial status summary. Categories D and E do not form part of either the tish or Suffolk lists. Species from these Categories that occurred in Suffolk in 2007 are luded as appendices to the main list. The order and nomenclature follow the latest published for The British List by the British rnithologists' Union (BOU 2006). This list can be accessed on their web site at vvw.bou.org.uk English names follow the same list. Subspecies are listed under the main species' heading, which includes the scientific name. The records for each species are listed mostly under the parish where the bird occurred, nietimes followed by a more precise location if known. The exception to this is at the river estuaries and larger, well-known sites criss-crossed by several parish boundaries e.g. • alberswick NNR, Minsmere, Orfordness, Alton Water, etc. The gazetteer on page 160 y ves locations for those sites not easily located on a standard road map. The order of records is north to south down the coastal region, working round the estuaries, then inland from the northeast to the southwest of the county. To minimise any potential threats to site security, some records of rare breeding birds are published anonymously and under a vague site heading. As much use as possible is made of systematic monitoring schemes such as the WeBS counts. Using such co-ordinated data instead of maximum counts gives a better idea of the Populations of each species wintering in the county on a given date. However, fluctuations ln n u m b e r s due to changing weather patterns will affect totals and higher counts are given ln e text after the table where appropriate. Counts from North Warren include Thorpeness 39
