Appearance:

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.

Appearance:

In all plumages told from Great Grey Shrike L. excubitor by very long primary projection, stout bill, large rectangular wing patch and extended white at base of tail. Tertials without white edge. Adult birds with black forehead (more extended in male and often speckled grey in female), and a pink wash to underparts (especially male). Immatures lack the black forehead and wing coverts have pale fringes.

Sound:

Contact call a series of Magpie-like "che-che-che". Two very different types of territorial song: Most diagnostic is the short song which consists of a single, parakeet-like "irtscha". Like in a sneeze, with rapidly rising and falling pitch. Given monosyllabic, disyllabic or in series. Other song type very varied with lots of mimicry of other birds and mammals. Similar to Woodchat Shrike but usually also includes the call from the short song. The varied song is more subdued in mated males.
