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.

Appearance:

Only small wader in the region with a dark or spotted belly. Most common small wader in area, and an important reference species when identifying congeners. Bill quite long with slightly curved tip. Legs dark. Summer plumage with unmistakable large black patch on belly, and variable warm, rufous brown back. Juveniles and moulting adults usually shows at least some diagnostic dark spots on belly in contrast to white flanks. White V-shaped markings on back, but not as striking as in juvenile Little Stint. Only adults in winter plumage shows completely white underparts (and uniformly grey back).

Sound:

Contact call a diagnostic, very nasal "trrreeet" . Given throughout the year and in many situations, including when being flushed. Song: A drawn out, nasal "tweeet", and ringing variations on the contact call in decrescendo. Low chattering heard from feeding birds.
