Kittiwake (Rissa tridactyla)
Peregrine Falcon (Falco peregrinus)
Small and agile gull with all black wing-tips, black legs (adults) and yellow bill. Area close to wing-tips much paler than rest of wings, and often visible at surprisingly long range (more so than the black tips). Adult winter with grey neck and black half-collar. Juveniles with black zig-zag pattern to wings, resembling pattern seen in Little Gull, Ross's Gull and Sabine's Gull. Differs from those in; no dark bar on secondaries, underparts of wing white, back grey, black on primaries reaches wing-tip. Flight action different from larger gulls; fast, stiff wing-beats and elegant maneuvering even in strong winds.
Sound:Highly vocal at breeding ground. A mewing "kitti-wake", with the pitch rising on the second drawn out syllable, and then falling. Generally silent elsewhere, except when squabbling over food.

Large and athletic falcon. Adults slate-grey above. Underparts white with black barring. Head almost black. Juveniles with brown tone to plumage, coarse longitudinal streaking below and paler head. Differs from the smaller falcons by less pointed wings, heavier hips and short tail. Highly contrasting and broad moustache-stripe. Smaller than Gyrfalcon with a more compact silhouette. The wings are not as broad, and belly not as deep. Underside of wings evenly barred, without contrasting coverts. Flight-pattern can recall Fulmar, with shallow, stiff wing-action.
Sound:A harsh, drawn out "kiaaaa" with emphasised endings repeated in series. Much slower than Merlin, but higher pitched than Gyrfalcon. Also shorter, coarse warning-calls.
