The purpose of this report is to provide a review of the bird and marine mammal observation data for the EMEC Billia Croo wave test site from 2009 to 2011. This report can assist in understanding the spatial and temporal distribution of wildlife at the test site, and specifically enable identification of where and when particular species are more likely to encounter test devices or related deployment activity. It provides information on how the most frequently occurring bird and marine mammal species use Billia Croo wave test site. This included: common eider, red-throated diver, northern fulmar, northern gannet, European shag, great skua, gull species, black-legged kittiwake, tern species, common guillemot, razorbill, black guillemot and Atlantic puffin, as well as grey and common seals, and harbour porpoise.

The aims were to explore relationships (if any) between the more frequently observed bird and mammal species’ site usage and environmental variables.
Completed, published report is publically available.
- Almost all species showed spatial variations in their use of the Billia Croo site;
- Almost all species analysed also showed seasonal variation in their use of the site, which reflected the breeding and wintering habits that are typical for the species; and
- Encounter rates were found to differ under particular environmental conditions, including wind strength, direction and glare extent.
