Herring Gull (Larus argentatus)
Rufous-tailed Rock-thrush (Monticola saxatilis)
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.

CCCompact built bird attached to rocky habitat. Differs in all plumages from Blue Rock-thrush, Monticola solitarius by short, rufous tail and shorter bill. Primary projection very long, and wing-tips almost reaches end of tail in perching birds. Male in breeding plumage unmistakable with blue-grey head, orange-buff underparts and white patch on back (variable). Male resembles female and immature birds when not in breeding plumage, but can sometimes be sexed by partly grey head and hints of white on back. General characteristics of non-breeding plumage are greyish brown and speckled upperparts, and orange-buff, vermiculated underparts. Then told from female Blue Rock-thrush by aforementioned different build, bill and tail, and also by paler throat-sides/breast and warmer rufous flanks. Posture usually upright with giss resembling more a wheatear than a thrush.
Sound:Alarm call a soft, wheatear-like "peeu", often accompanied by harder "tek" calls. Also a very nasal, drawn-out wheeze. Song varied and pleasing, and often very difficult to tell from Blue Rock-thrush. It is generally softer, more varied and the deeper notes are less tremulous and vibrating. A higher proportion of the song is in the higher register, with fewer lower fluting sounds, and more mimicry. Both sexes sing, but females less than males.
