Digital video aerial surveys were conducted between 2015 and 2020 by HiDef Aerial Surveying Ltd (‘HiDef’) and commissioned by DONG and Ørsted as part of their post-consent monitoring programme for Burbo Bank Extension offshore wind farm. Eight surveys were completed between January-March in 2015, 2018, 2019 and 2020. The aim of this monitoring programme and report is to provide updated density and abundance estimates for red-throated diver, common scoter and the waterbird assemblage within the SPA. Estimates for other species, including little gull, red-breasted merganser, and cormorant were included in this report as components of the waterbird assemblage.
