Appearance:

Small and compact, green and yellow bird. Smaller than Linnet and Siskin, with heavily streaked flanks, and stubby, deep and grey bill. Rump yellow in adults, but immature birds lack yellow tones in plumage altogether. Wing-bars narrow and much less marked than in Siskin, forehead in males bright yellow. Fairly long-winged with deeply forked tail. Flight light and bouncing. Song-flight of male characteristic, with butterfly-like gliding and slow-motion wing-beats.

Sound:

Song a hectic, jingling, continuous trill, like the pouring of broken glass. The highest notes are constantly modulated to form vague motifs. Timbre comparable to Corn Bunting. Ringing trill also used as contact call, with slightly falling pitch "trrilrlitlitlit". Alarm call a short, redpoll-like "weee-eeet", with an accented high-pitched middle part.

Appearance:

White with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.

Sound:

Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
