Yellow-browed Warbler (Phylloscopus inornatus)
Hooded Crow (Corvus cornix)
Small and secretive warbler, usually discovered by the contact call. Broad, yellow/whitish wing-bars framed in black, and dark tertials with pale fringes gives the species a contrasting plumage. Long and strong yellow supercilium (lacking the orange base of Pallas' Leaf Warbler). No central crown-stripe. Slightly smaller than a Chiffchaff, with smaller bill and shorter tail. Rump same colour as back (as opposed to Pallas'), and overall greener and more strikingly coloured than Hume's Leaf Warbler (but beware individual variation).
Sound:Contact call and song both distinct. Contact call a very high-pitched "zeeoooee", with pitch rapidly dropping in the middle, and ending on a quickly rising note. Song an ornamented, drawn out, slow-motion version of the contact call, with similar timbre and pitch.

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.
