Herring Gull (Larus argentatus)
Red Kite (Milvus milvus)
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.

CCA medium sized, long-winged raptor, with deeply forked tail. Adults with warm brown underparts and typical whitish "window" contrasting with black wing tips. Tail rufous above. Easily confused with Black Kite, but this has shallower forked tail and gives a darker brown impression. Note that birds gliding with tail fanned may give impression of less forked tail. Flight elegant, with frequent and typical tail twisting to maintain position in the air.
Sound:Mainly heard in breeding season. A piercing long whistle, quickly ascending, then descending "piuuu". Often used in movies to give an eerie wildlife mood. Differs from Black Kite in being a clear whistle all the way through the call, without "shivering". Higher pitched than Buzzard, and with less pause between calls.
