Appearance:

Notably smaller than Curlew. Bill is shorter and curves more closer to the tip. Markings on head much more prominent than in Curlew, with double dark lateral crown-stripes (light stripe on top of crown) and dark eye-stripe. Note that young Curlews have noticeably shorter bill than adults! Gives an overall darker impression than Curlew, especially underwing and flanks.

Sound:

Song starts similar to Curlew with long wailing notes "kluuueee", which then accelerates to a continuous, vibrating single note. Lacks the cyclic phrase ending of Curlew.

Appearance:

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.
