During December 2003 and February 2004, JNCC conducted aerial surveys of wintering aggregations of seaducks, divers and grebes within a number of UK inshore areas. The aim of the surveys was to collect data on the wintering numbers and distribution of inshore waterbirds in areas of the UK known to be important for this group of species. The surveys were carried out as part of JNCC's annual programme of surveillance of wintering inshore waterbirds in the UK.
The areas covered by aerial surveys in 2003/04 were Scapa Flow, the west coast of the Outer Hebrides, Coll and Tiree, part of the west coast of Mull, the Dornoch, Moray and Inverness Firths, Aberdeen Bay, the Firth of Forth, the Firth of Tay and St Andrews Bay. Surveys were conducted from light aircraft, following a line-transect method designed to collect data that were suitable for both distance sampling (to estimate total numbers of birds) and geostatistical modelling (to identify areas with the highest densities of birds). In addition, shore-based counts were conducted within the Aberdeen Bay area in February, March, April and May 2004 to provide additional data on inshore waterbird numbers.
