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:

Elegant and very long-tailed wagtail. Vent always bright yellow in all plumages. Legs pinkish flesh-coloured, not black. Wings with single white bar, visible both from below and above. Male with black throat in summer. Constantly wags tail, often in a more horizontal posture than congeners. Flight more attenuated and more bounding than in other wagtails. Attached to water and streams.

Sound:

Contact call short, metallic and with a clipped ending. Often disyllabic, "tzeet-tzeet", with each syllable more separated than in White Wagtail, and timbre more "dirty". Song simple but variable. Often starts with the contact call, followed by short melodic phrases. Sometimes with more elaborate song-flight like White Wagtail.
