Hooded Crow (Corvus cornix)
Red-backed Shrike (Lanius collurio)
Unmistakable, if not in silhouette. In poor light or at a distance, when the grey plumage is not visible, confusion with other crows is possible. Bill is deeper than in Rook, and the upper mandible more curved towards the tip. Smaller than raven, and much less heavy bill. The wings are shorter and more rounded, and the tail is not wedge-shaped. Posture less upright than Rook.
Sound:Cawing is aggressive and more raucous than in Rook, with more rolling r's. Has a large repertoire of seldom heard calls, and even sub-song. Many of these calls are surprisingly resonant and pleasant sounding, and sometimes resembles Raven. Probably impossible to tell from Carrion Crow with certainty by sound alone.

CCMale with brown back, pinkish white underparts and a bluish grey head with a black eye mask. Female more dull with barred underparts. Juvenile like female, but upperparts also barred . Tail brown with white edges in all plumages. Females and juveniles easily confused with other southern/eastern or vagrant shrikes like; Brown Shrike, Isabelline Shrike, Woodchat Shrike and Turkestan Shrike. Differs from those in white sides of tail, barred rump, mantle and scapulars, scaly underparts and dark or yellowish base of bill (not pink).
Sound:Call a hard "check check" (like striking two rocks together), and a variable nasal "twee" Song surprisingly varied with many expert imitations of small passerines, interwoven with bell-like ringing and dry chirping sounds. May be confusing and hard to identify if bird not seen. Song not very loud, but phrases can be very long.
