HiDef Aerial Surveying Limited (HiDef) and Wildfowl and Wetlands Trust (Consulting) Limited (WWT Consulting) undertook post-construction aerial bird surveys in the LID wind farm area using HiDef’s digital recording system.Four surveys were conducted in mid to late winter (January to March) 2011. Surveys followed a series of randomly assigned transects oriented east-west along Ordnance Survey (OS) grid lines, and spaced 2.5km apart over the main survey area and 1.25 km apart in a high interest region covering the waters immediately around the LID wind farm footprint. Four high definition digital video cameras, attached to the underside of an aircraft, recorded images along each transect, with each camera covering a 50m wide strip. Images were scrutinised by experienced ornithologists from WWT Consulting to detect and assign species and species groups to birds.

The survey aircraft was flown at 2000ft with four cameras, attached to the underneath, recording images along each transect at 2cm resolution with each camera covering a strip 50m wide (thus the total strip width was 200m). Each of these strips comprises an individual sample set. Images were scrutinised to detect birds and identify the species or species group with an associated level of confidence in the identification. A more detailed methodology is described below.
