North East Scotland Breeding Bird Atlas 2002-06
All breeding birds recorded during the 5 survey years 2002-06, except for sensitive and confidential records (for further information on these see section 8). See <a href=' http://www.nescotlandbirdatlas.org.uk'>www.nescotlandbirdatlas.org.uk</a> for further details.<br /><br />
Data were classed in four categories of breeding status as follows: <br />
<li>Observed: 3,407 records</li>
<li>Possible: 22,183 records</li>
<li>Probable: 23,258 records</li>
<li>Confirmed: 31,935 records</li>
It should be noted that the 'Observed category' comprises records of birds that were 'present but not breeding'. E.g. foraging gulls, Rooks, Herons, Swallow, House Martin, Sand Martin etc.
All records come from a) the North-east Scotland recording area and b) the Moray part of the Moray & Nairn recording area (i.e. Nairn was not covered by the survey) (see <a href=' http://www.thesoc.myzen.co.uk/soc-recorders.htm'>www.thesoc.myzen.co.uk/soc-recorders.htm</a>). All 2,341 tetrads in North-east Scotland and Moray were visited. <br /><br />
Over 340 observers submitted 115,400 records for a total of 179 species. These are presented here as maximum breeding status for each species in each tetrad over the survey period, reducing the number of individual records to 80,783. No attempt has been made to analyse recording effort, but it was thought to be good across the whole area. Records of species present during the breeding season, but not showing evidence of confirmed, probable or possible breeding (e.g. Red-throated Divers off-shore) have been EXCLUDED from the dataset.
The aim of the survey was to build a complete picture of the breeding distribution of birds in North-east Scotland and Moray at tetrad scale. This will update the Birds of North-east Scotland Atlas which covered the period 1981-84.
The data are of high quality, having been checked and verified by the Local Recorder and the NESBBA Working Group.
Data were collected during systematic surveys of all the tetrads in North-east Scotland and Moray. All records have been validated by the NESBBA working group. All records are geo-referenced at 2x2 km scale.
