Appearance:

May be confused with Ruddy Shelduck, but differs in long, pinkish legs, pink bill, long neck, greyish underparts and striking, brown mask. Conspicuous black and white wing pattern similar to Ruddy Shelduck, but crossed with a thin, black stripe. Sexes similar. Immature duller and without facial mask, and thus closer to RS in appearance. Spends much time foraging while walking, but may also dive. Flight heavy and goose-like.

Sound:

Quite vocal when interacting. Female calls may resemble RS, but are coarser, harder and trills are more rolling. Single calls are longer, and falls markedly in pitch. Male calls quite different, with husky, wheezing or hissing "kaahhh", or with the same timbre in series lika a steam engine.

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.
