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:

Small raptor with long tail and short, rounded wings. Quite similar to Goshawk, and female Sparrowhawks may approach male Goshawks in size (female much larger than male in both species). Upperparts grey in male, and brownish in female and juvenile. Underparts barred in buff in male, and brown barring in female and juveniles. Supercilium may be prominent in females. Less bulky than Goshawk, with more slender hips and less deep chest. The sharper corners of the tail is visible when soaring.

Sound:

Series of short "ke-ke-ke-ke-ke", with rising pitch. Less resonant and less full than similar call of Goshawk, and much faster. Also a short "peeaaaa", shorter and more squeaky than Buzzard.
