Hooded Crow (Corvus cornix)
Mistle Thrush (Turdus viscivorus)
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.

CCA large, and often shy, thrush. Most similar to Song Thrush. Other than size, it is distinguished by a long tail with white corners, white under wing-coverts and a pale, vertical cheek patch. Underparts are boldly covered in round (not arrow-shaped) spots that forms a dark patch on each side of upper chest. Rump slightly paler than the olive back. Noticeably bulkier than Fieldfare, with a heavier bill. Posture upright when foraging on ground, and head seems paler than the back. Flight non-undulating, but with alternating bursts of wing-beats and glides with folded wings. Often flies high.
Sound:Song loud, far reaching and melodic. Most similar to Blackbird, but pitch is higher, phrases shorter (3-6 notes) and most notably, pauses between phrases are much shorter. All which gives the song a much more hurried feel than that of the Blackbird. Timbre is thinner and slightly shivering, and tonal range more limited. May have recurring favourite motifs, but does not repeat phrases like Song Thrush. Sometimes adds higher pitched parts and imitations. Other calls; a dry rattle, likened to the sound of a piece of wood drawn over a coarse comb, and a Fieldfare-like "chuck".
