This section is unfinished. It is a work in progress.

The Verification of all the records was a long and tedious task, however, website technology allowed validation at both national and local level to be carried out simply and efficiently. County verifiers were Andrew Green, Colin Jakes, Dr Peter Lack, Nick Mason, Steve Piotrowski, John Walshe and Mick Wright.

The completed dataset contained a grand total of 488,897 records for Suffolk, comprising 216,531 records for the winter months (November 2007 to February 2011) and 272,364 for the breeding season months (April 2008 to July 2011). The breeding season total included records of observations for March and August to October, which had a breeding status assigned.

The total number of species recorded during the winter period was 277, and for the summer period 335, which included 147 breeding species.

The number of individuals that sent in records totalled 1070. There were 570 individuals that sent in more that 50 records; the top three people for sending in records were David Cawdron (36,000), Malcolm Fairly (19,000) and Stephen Goddard (18,000).

Maps: A comprehensive list of maps can be seen for summer and winter on Distribution and Change in the Species maps section of this site. These maps have been plotted at the tetrad level. Five rare bird species were mapped at a 10 km level with a single icon at its centre regardless of the number of birds or territories.

Interpreting Maps:

Suffolk Bird atlas species density maps based on info from the BTO surveyed from 2007 -2011. Below are the species density maps

This part of the result section examines this dataset in more detail and discusses, with maps and tables a range of results not covered in the main body of the species maps:

Total Species Density

Winter Species Density at Tetrad Level

Winter Density Map During the winter period almost 70% of all the County’s tetrads only held between 1 and 50 species of birds and a further 314 tetrads (29%) held between 51 and 100 species per tetrad. These relatively species rich tetrads were predominately on the coast, Waveney valley, the areas around Lackford and Livermere and the hinterland areas associated with the county’s tidal estuaries. Less than 3% of Suffolk tetrads held between 101 and 163 species. These hot spots for bird species occurred along the coast at Kessingland, Benacre, Southwold, Walberswick, Minsmere, Orford Ness, East Lane, Landguard and inland at Melton, Martlesham, Wherstead, Trimley, Oulton, Lackford and Lackenheath.

Summer Species Density at Tetrad Level

Summer Density Map There are large areas of Suffolk (53%) where the number of species was less than 50 per tetrad, a further 491 tetrads (45%) held between 51 and 100 species per tetrad. There were only 18 hot spots where the number of species per tetrad was between 101 and 147. The hightest was TM46T, which contains RSPB's reserve at Minsmere followed by TM23V which contains the Landguard Bird Observatory
