Skylark (Alauda arvensis)
Herring Gull (Larus argentatus)
Short foldable crest. Pale eye-ring and supercilium. Long primary projection (primaries extend well beyond tertials), white trailing edge to wing and white outer tail feathers. Tail much longer than in Wood Lark.
Sound:Song a pleasing energetic stream of chirping, merry trills, interspersed with mimicry. Trills quite resonant with fairly full tone. Song usually given in flight high in the air. Less characteristic, shorter, weaker and more varied song when given from ground. Most typical flight call a short trilling "chirrup", with the end note noticeably lower pitched than the start. Also several other more cryptic calls.

CCLarge 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.
