Marmora's Warbler (Curruca sarda)
Kittiwake (Rissa tridactyla)
Very similar to Balearic Warbler but breeding range does not overlap. Also easily confused with sympatric Dartford Warbler due to similar build with long tail, high crown, short wings and spiky bill. Told from latter by all over lead-grey plumage, lacking vinous underparts. Female similar to male but lacks dark lore and throat is paler . Immature birds are very similar to immature Dartford Warbler and are best identified by call, but have less brown back, paler throat and dirtier and greyer underparts.
Sound:Song hurried and similar to both Sardinian, Dartford and Spectacled Warbler, but is softer with more tinny timbre. Interwoven soft rolling "trrrrtrrr" usually become more prominent towards the end of each phrase which often is concluded by 3-4 clear whistling "wit". Alarm call a short, Stonechat-like and grating "treck", very different from both Balearic and Dartford Warbler.

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.
