Appearance:

Very deep and heavy, conical bill. Large head and bull-neck, gives the bird a front-heavy appearance, especially in flight. The short tail adds to the impression. Wings with broad, white bars and tail with white terminal band. Bill grey in breeding plumage, and yellowish in winter. Largely unmistakable, but easily overlooked when hiding high in foliage. Often flies high, even for short distances. Flight heavily undulated.

Sound:

Most typical call a sharp and explosive "tzek", with abrupt, emphasized, cut-off ending. Quite similar to Robin, but harder, with each syllable marginally longer with a slightly wheezing timbre. Repetitions are slower and more singular than Robin. Diagnostic when interspersed with high frequency notes.

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.
