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.

A small wader with yellowish legs and short, almost straight, dark bill with pale base. Noticeably smaller than Dunlin, and with shorter and straighter bill. Similar in size to Little Stint, but legs light yellowish, tail longer with white edges and markings on back quite plain. Clear divide between markings of breast and white underparts. Juveniles with prominent scale-pattern on back. Upperparts of adults in winter plumage more evenly grey, lacking the star shaped spots of summer. Prefers fresh or brackish waters, even on migration.

Sound:

Call a hard, thin, ringing "trrrrrr". Song a cyclic series of variations on the call; "trrrrrrrr" rising and falling in pitch. Often sustained for several minutes at a time.
