Abstract: | Some 3,000 pairs of Herring Gulls are now known to be nesting on buildings, mainly in coastal towns they are increasing most rapidly in eastern Britain, where recruitment is taking place from natural colonies. A smaller number of Lesser Black-backed Gulls has occupied rooftops in the Bristol Channel region. |
