Serin (Serinus serinus)
Spotless Starling (Sturnus unicolor)
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.

CCSimilar to Starling, and may be difficult to tell apart in winter and immature plumages. Most birds are in breeding plumage from March on, completely lacking spots, and with a purple (not green) sheen. Flight feathers lacks pale fringes, and the overall look is much darker than Starling. Elongated head and throat feathers are slightly longer than in Starling. Winter and immature plumage birds difficult to identify, but has small and spearhead-shaped spots, and darker wings (due to lack of pale fringes). Leg colour generally paler pink, than Starling, but some overlap occurs.
Sound:Similar to Starling in form and variation, but the long, descending whistling notes are more dominant and accented. Sometimes uttered as trills, or "stuttered". Whistles also used as contact calls when not breeding.
