Surveys were undertaken from two Vantage Points (VPs) on the coast of Islay, Coull Point and Frenchman’s Rocks, between mid September and mid November 2012. Target species were geese and waders using the west coast of Scotland as a migratory flyway either to wintering destinations on the island of Islay or locations further south, including Ireland. All target swan and goose species were recorded with the highest numbers comprising barnacle goose, a qualifying species of three Special Protection Areas (SPAs) on Islay. In some cases these birds approached Islay from the direction of the proposed wind farm flying at heights between 20 and 200m above sea level, i.e. potentially at rotor height. This is more likely to occur when strong easterly winds pushed large numbers of migrating geese off course towards Ireland. Collision modelling could incorporate this risk by inspecting the number of days when such weather conditions occur and incorporating them in to calculations.
