Appearance:

Very similar to Herring Gull, and not always possible to identify with certainty. Generally thicker neck, rounder head and longer wings than Herring Gull. Adults: Silvery upperparts, bright yellow legs (beware that it is not uncommon for Herring Gull to have yellow legs!), and more black and less white in wing-tips. Bill heavier than H.G. with markedly curved tip. Orbital ring red, not orange. Big, red gonys spot, often extending to upper mandible. Marked gonys angle. Primary feather P5 (counted from innermost feather in gulls) usually with broad, black band. In winter plumage head is less streaked than in H.G., and often completely white. Immatures first winter: Pale belly and head. Dark underwings with blotchy markings. Only vague pale window of inner primaries, and well defined, wedge-shaped tail-band. Dark base of bill. For a detailed account of all plumages see Gull Research.

Appearance:

Unmistakable in breeding plumage with golden, speckled upperparts and white-bordered black throat and belly. Male generally blacker than female, but due to regional differences, some females may be darker than males from other areas. Juveniles and birds in winter plumage, lacks the black underparts, and could be mistaken for Grey Plover. Differs from that species in more golden coloured back, less heavy bill and neck and by being slightly smaller. In flight easily told apart from Grey Plover, Pacific Golden Plover and American Golden Plover by white axillaries.

Sound:

Most common call at breeding ground a disyllabic, melancholic and wailing whistle with the end falling in pitch. In song flight also a trilling, warbling and cyclic "preecaria-preecaria-preecaria". Contact call a straight, short "kluee".
