Herring Gull (Larus argentatus)
Nightingale (Luscinia megarhynchos)
Large gull with deep chest, light grey back and heavy yellow bill with red spot (adult). Pinkish legs and black tipped primaries with white windows. Winter plumage with streaked head and neck. Develops grey mantle in 2.nd winter. Young birds may be difficult to distinguish from juvenile Greater- or Lesser Black-backed Gulls, and the species shows notable variation in both plumage and size. Juveniles generally shows darker head and less contrasting markings than Greater Black-back, and pale inner primaries (window), as opposed to the all black hand of young Lesser Black-backs.
Sound:Quite vocal. A long and strong "ay-kay-kay-kay-kay" with fading strength commonly heard. A deep "ga-ga-ga" heard from anxious birds. All calls much deeper pitched than Common Gull. Difficult to distinguish from Lesser Black-backed Gull, but tone is less nasal.

CCVery similar to Thrush Nightingale. Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Tail rufous brown, upperparts warm brown. Underparts buff and white. Throat without streaking. Tail more rufous, and contrasts less with the warm brown back, than in Thrush Nightingale. Overall a more smooth and clean appearance. Thrush-like behaviour despite the small size, with jumping gait, erect posture, raised tail and drooping wings.
Sound:Alarm call either a thin, flycatcher-like "weeet", or a Chiff-chaff-like "piuu". Also a characteristic (but similar to Thrush Nighitingale) dry, rattling, frog-like "rrrrr". The song is the best characteristic to separate it from T. Nightingale. It consists of extremely resonant, full-bodied notes and lacks the, dry, rolling, rattling sounds of T.N. Most distinct species specific sound is the interwoven series of slightly ascending, plaintive notes (0.04 - 0.10 in recording). May mimic Thrush Nightningale!
