Suffolk Birci Report
2007
The 2007 Suffolk Bird Report Systematic List Introduction The list and its appendices have been written using data supplied by the county's birdwatchers and conservation organisations. The raw data have been collated and interpreted by the following: Swans, geese and hérons Ducks Game birds, rails to crâne Divers to Shag Raptors Oystercatcher to Ruff Snipes to phalaropes Skuas to gulls

The 'officiai' British list is maintained by the British Ornithologists' Union (BOU). Species are included in various catégories according to their status, as follows: • Category A - species which have been recorded in an apparently natural state at least once since January Ist 1950; • Category B - species that would otherwise be in Category A but have not been recorded since December 3Ist 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 Catégories A or B except that there is doubt that they have ever occurred in a natural state; • Category E - species that have been recorded as introductions, transportées or escapees from captivity, and whose breeding populations are not thought to be self-sustaining. The main part of the species accounts consists of species that occurred in Suffolk in 2007, which fall into Catégories A and C. Where a species is included in multiple catégories, this is shown in the initial status summary. Catégories D and E do not form part of either the British or Suffolk lists. Species from these Catégories that occurred in Suffolk in 2007 are included as appendices to the main list. The order and nomenclature follow the latest published for The British List by the British Ornithologists' Union (BOU 2006). This list can be accessed on their web site at www.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, sometimes 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. Walberswick NNR, Minsmere, Orfordness, Alton Water etc. The gazetteer on page 161 gives locations for those sites not easily located on a standard road map. The order of records is north to south down the coastal région, 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
