Greenfinch (Chloris chloris)
Alpine Chough (Pyrrhocorax graculus)
Plumage green, grey and yellow. Note bright, yellow base of primaries and sides of tail in all ages and plumages. Deep and heavy conical bill. Tail forked and quite short. Plump build. Female more grey than male, with back diffusely streaked in brown and underparts greyish. Juveniles similar to females, with even more drab colours and heavier streaking (also on underparts). Strongly undulated flight. Often appears somewhat clumsy when trying to perch on feeders etc.
Sound:Song composed of various sequences of linked sounds, repeated in a vibrating manner; "trrrrrrrrr", "chechechecheche". Sometimes resembles Brambling when making the wheezy "rrrrrrrrr" sound, but differs in being harsher and by "pulling" the pitch downwards (or sometimes upwards) at the end. Contact call a fairly resonant "chep-chep", resembling Redpoll, but less nasal and with a fuller tone. Also a sharp, drawn, ascending "kooeee", (perhaps not obviously recognized as a finch).

CCAll black plumage, red legs and relatively short and straight, yellow bill. Note that immature Red-billed Chough has yellowish-brown bill, but never as pure yellow as in Alpine Chough, and the whole bill is curved. Easily confused with Red-billed Chough at a distance where both species occur, but note more narrow, less fingered wings, and longer, more rounded tail. Resembles Jackdaw in size, but flying Alpine Choughs differs by two-toned underparts of wings (darker coverts). Flight acrobatic, but a little more stilted than Red-billed Chough.
Sound:Diagnostic and very different from Red-billed Chough. A sharp, quite high-pitched, whistling trill "chreeeee". Usually alternated with pure-toned high-pitched whistles, falling abruptly in pitch with a "clipping" ending.
