About This Species

Look for this dark-backed gull on coastal cliffs, estuaries and increasingly on urban rooftops across Britain and Europe, distinguished from the paler herring gull by its slate-to-blackish upperwings. Many birds migrate south for winter, so summer is the best time to find breeding adults near colonies. It forages widely, following ploughed fields and scavenging opportunistically.

Ethical Viewing Guidelines

  • It nests colonially on cliffs, islands and rooftops, and defending adults can become aggressive toward anyone approaching chicks, so keep a clear distance during the breeding season.
  • It is protected under the UK Wildlife and Countryside Act 1981 and comparable legislation elsewhere in its European range.
  • Avoid lingering near nest sites and give roof-nesting colonies in towns a wide berth in summer.
