Neck with incomplete black band, creating contrasting, jagged edge. Heavy, goose-like flight.

Song: Like a slow Black-throated Diver. Pitch slowly rising with a register break, progressing into a cyclic, two to four syllable, motif. Also various vibrating eerie descending calls. Often used as sound effect in horror movies.

Appearance:

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).
