Rock Sparrow (Petronia petronia)
Rook (Corvus frugilegus)
Heavily streaked sparrow with diagnostic combination of broad, strong supercilium and white spots at end of tail. Bill deep and cone-shaped with yellow to pinkish base. Primary projection very long. End of under tail coverts pale, giving the bird a broadly barred rump. The white pearls on the short tail and the long wings are conspicuous in flight. Adults with yellow throat-patch, although this is often hidden in many postures. Agile flight, much superior to Passer with regards to both speed and maneuverability.
Sound:Large repertoire of calls of which many recalls Passer, but all with a nasal timbre. Main contact call a nasal "peey-u", rising sharply in pitch and then ending one note lower on the last syllable. Recalls alarm call of Serin in timbre. Sometimes given with only the first syllable. Also a short and explosive "pit", and many less distinct calls when interacting.

CCAn all shiny black crow with diagnostic bare, pale grey base of bill, and "baggy trousers". Juveniles lacks bare bill base and are difficult to separate from Carrion Crow. Young Rooks however, has a steeper forehead and more conical bill with less curved culmen. Tail is more rounded and base of wings more narrow. Flight action includes less gliding than Carrion Crow, and individuals are more spread when a flock flies.
Sound:Makes similar caws as Carrion Crow, but is harsher, softer, flatter with less rolling r's. Also gives a varied song of soft gurgling and rattling sounds, interwoven with calls at breeding ground.
