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.

Sound:

Voice more nasal than Herring Gull, but ID by sound difficult.

Appearance:

Adult breeding birds unmistakable. White mask, warm rufous brown throat and underparts. Bill noticeably heavier than in Red-necked Phalarope in all plumages and and ages. Female more brightly coloured than male (reversed dimorphism). 1st winter birds differs from Red-necked in white fore-crown, while fresh juveniles have less contrasting markings on back. Both mentioned characters are often difficult, or impossible to use at a distance. With experience and practise, one can use the powerful flight and more stocky build as field marks.

Sound:

Flight-call a short and sharp, Coot-like "kit". Cleaner and higher pitched than Red-necked Phalarope. Display sound a rolling cooing, at stable pitch. Other calls: a hissing like the squeezing of a rubber duck, rising quickly in pitch and ending abruptly.
