Yellow-legged Gull (Larus michahellis)
Garden Warbler (Sylvia borin)
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.

CCAn almost featureless, large warbler with greyish brown upperparts and buff underparts. Lack of distinct characters is a character! Most distinct character is probably the faint, slate grey half-collar. Vent has no markings, eye is dark and bill is relatively short. Body quite plump, and facial expression gentle and mild. Usually stays hidden in foliage. Lacks nervous behaviour of other Sylvia, and does not normally flick its tail and wings.
Sound:Song: a full bodied, flowing, melodious stream of notes, distinguished by its almost constant, warbled quality and lack of clear whistling notes (see Blackcap). Tempo is fairly even. Beware confusion possibility with occasional subsong of Blackcap that never reaches the whistling part! Call a nasal "che". Alarm call a hard "check", and a hoarse "tcherr".
