The slaty-backed gull is a very large North Pacific gull with dark slate-grey wings, a broad white trailing edge and pink legs. It breeds on rocky coasts and islands and disperses south in winter. A powerful opportunist, it takes fish and marine invertebrates, raids seabird colonies for eggs and chicks, scavenges carrion and gathers around harbours and fishing vessels (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
