Overview
The Common Gull is, confusingly, not Britain's most common gull — Black-headed and Herring Gulls both outnumber it. It occupies a middle size between the smaller Black-headed and larger Herring Gull. It has a gentle, dove-like expression with rounded head and dark eye — quite different from the fierce yellow-eyed Herring Gull. Follows agricultural machinery on farmland behind the sea wall in winter and roosts at Marshside.

Frequently Asked Questions
How do I tell Common Gull from Herring Gull?
Size and bill are the key features. Common Gull is noticeably smaller with a more rounded, gentle head and dark eye. The bill is thinner and yellow-green with no red spot (Herring Gull has a yellow bill with a distinctive red spot). In winter, Common Gull has finely streaked brown on the head; Herring Gull has heavier blotchy streaking.
