The common gull is a medium-sized gull that breeds on Scottish moorland and coasts, wintering widely on farmland and coastal habitats across the UK.
Common gull welfare is linked to breeding habitat security and winter food availability. Moorland breeding sites are vulnerable to predation pressure from foxes, mink, and corvids, particularly at low-density breeding locations. Urban roof-nesting birds face disturbance from building maintenance and deliberate nest removal. Winter farmland birds benefit from earthworm availability in grazed pasture. Gull welfare in urban settings is complicated by human-wildlife conflict around food provision and nesting. Humane deterrence methods at problem nesting sites are preferable to lethal control. Recording breeding population changes through monitoring schemes helps identify causes of decline.
