2001-2002, Casella Stanger Ltd., North Hoyle Offshore Wind Farm, Ornithological Study, Technical Report series https://portal.medin.org.uk/portal/start.php?tpc=015_a01f76ed-da94-408d-b1f6-1b141a0fba89 Surveys of Liverpool Bay during 2000/2001 have demonstrated that the inshore waters have wintering populations of common scoter and red-throated diver that would justify classification of parts of the Bay as European Sites for these species. A number of other populations, from designated sites of importance for birds, use the offshore waters of the Bay. Common, sandwich and little terns from The Dee Estuary SPA and potential extensions feed offshore, as do cormorants from breeding colonies at Puffin Island SPA and Little Orme’s Head SSSI and, in significant numbers, shag, guillemot and razorbill from the breeding cliffs of Great Orme’s Head SSSI. All of these populations are qualifying features of the designated sites. The report presents the methodology adopted in the assessment of these ornithological issues. 20070319 2005
