Assessing habitat use of Herring Gulls in the Morecambe Bay SPA using GPS tracking devices

Number of coastal Herring Gull populations have reduced markedly in recent years. The breeding gull colony of the South Walney and Piel Channel Flats Site of Special Scientific Interest (SSSI), within the Morecambe Bay and Duddon Estuary potential Special Protection Area (pSPA), is of national and intermational importance for its number of Herring Gull Larus argentatus and Lesser Black-backed Gull Larus fuscus.

Improving understanding of the possible relationship between improving freshwater and coastal water quality and bird interest on designated sites - phase 1 review

Over the past 50 years there has been widespread improvement in water quality in many freshwater and coastal systems driven by domestic and European legislation, most recently the EU Water Framework Directive (EC Directive 2000/60/EC), but also including the Urban Waste Water Treatment Directive (EC Directive 91/271/EEC) and Bathing Water Directive (EC Directive 76/160/EEC).

Estimating national population sizes: Methodological challenges and applications illustrated in the common nightingale, a declining songbird in the UK

Large-scale population estimates of species are used for several reasons, including the assessment and protection of important sites. However, determining a national population requires extensive surveying and using methods that allow counts to be scaled up to the number of birds actually present and across a larger area.

Dodging the blades: new insights into three-dimensional space use of offshore wind farms by lesser black-backed gulls Larus fuscus

Initial findings suggest that Lesser Black-backed Gulls in north-west England fly within wind farms, but may avoid wind turbines once there.
