- Ichthyaetus relictus
Larus relictus
Identification
Length 44 to 45 cm, weight 420-660 g; wingspan not recorded.
Breeding adult reminiscent of second-summer Mediterranean Gull, with a black hood, pale silvery grey mantle and inner wings; outer primaries with white tips and black subterminal bands. Differs in the broader, more conspicuous white half-moon 'eyelids' (recalling Franklin's Gull), more rounded head, and shorter bill. Legs and bill dark red. Non-breeding adults lose almost all of the black hood, with only faint blackish ear coverts and hind crown, unlike Mediterranean Gull's more obvious black smudges; bill and legs often paler than in summer.
Juvenile and first winter similar to the same ages of Mediterranean Gull, but the latter's black bar on secondaries is reduced to a series of black spots in Relict Gull, head mainly white with faint black streaks, and bill also often paler; can recall the same ages of Common Gull as much as Mediterranean Gull.
Distribution
Breeds from Kazakhstan east to Mongolia, south-central Russia and northern China. Winters in eastern Asia, primarily near the East China Sea
Taxonomy
This is a monotypic species which like its congeners was formerly placed in the genus Larus. It is closely related to Mediterranean Gull, and was first described as a subspecies of it despite the differences in structure as well as plumage.
Habitat
Islands in saltwater lakes and estuarine mud and sandflats in summer; coasts in winter.
Status
Classified as Vulnerable in the 2008 IUCN Red List.1
Behaviour
Similar to Mediterranean Gull.
