Willow Tit (Poecile montanus)
Hooded Crow (Corvus cornix)
Very similar to Marsh Tit, but cheeks whiter, head bigger, and upperparts greyer with white wing-panel. Black bib wider and bigger than in Marsh Tit. Lacks white spot at base of upper mandible. Willow Tits in Great Britain are warmer brown and are more difficult to separate from Marsh Tit.
Sound:Call: Most characteristic call a frequently uttered, nasal "ti ti chaa chaa chaa". First notes high pitched and the following lower, coarse, nasal and drawn. Sometimes uttered without the introductory high pitched notes. Song: One or two soft, clear, melancholic notes repeated in a slow, even rhythm. At first rising slightly in pitch, then gradually falling. In some areas song is evenly pitched. Other sounds: high pitced "zi zi" similar to other tits.

CCUnmistakable, 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.
