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:

Most likely to be confused with Little Crake (P. parva). Most important field characters is the very short primary projection and lack of red base of bill. Some caution should be taken as missing or unorderly tertials can be confusing with regards to the projection, and immature Little Crake may sometimes also lack red base of bill. Flanks and belly more extensively barred than P. parva. Upperparts richer brown with white spots. Sexes alike, but females often with paler throat. Brown cheeks occurs in both sexes. Legs dirty olive colour and bill greenish. Immature even more easily confused with P. parva, but apart from the missing projection, note warmer brown upperparts and more heavily barred underparts, even on breast. Crown less evenly coloured than P. parva, with blackish speckles.

Sound:

Rich repertiore. Male song easily overlooked due to similarity to The edible frog Pelophylax esculentus., and to being audible only a few hundred meters. The sound, a rolling "trrrrrrrr", differs from frogs in being drier and more stable in pitch. Sometimes the pitch rises slightly in the beginning of the call, but then remains stable also at the end. The call is uttered in 1-2 seconds intervals and each call is 2-3 seconds long. Some overtone modulation is common (stable pitch but change of vocal "ooeeii"). Unmated female sings with a more hurried "wirrr". Alarm call a series of nasal, hoarse "weeat" or a sharp "kriik".
