Marmora's Warbler (Curruca sarda)
Tree Sparrow (Passer montanus)
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.

Differs from House Sparrow by warm brown crown, white cheeks, white (incomplete) collar and diagnostic, black cheek patch. From Spanish Sparrow by cheek patch, and lack of black breast markings. Brown and streaked rump. The black bib does not expand towards the chest. Head profile rounder and neater than House Sparrow, with slightly smaller bill. Identification by profile alone is possible with practice. Sexes and ages alike.
Sound:Distinct, high-pitched and explosive contact-call; "che-witt" typically given in flight. Second syllable rising rapidly in pitch. Most other sounds similar to House Sparrow, and may be difficult to identify. Chattering sounds are generally harder, and song slightly higher pitched than House Sparrow.
