Tree Sparrow (Passer montanus)
Gannet (Morus bassanus)
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.

CCWhite with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.
Sound:Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
