Spotless Starling (Sturnus unicolor)
Treecreeper (Certhia familiaris)
Similar 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.

CCUnmistakable, except in areas where it coexists with Short-toed Treecreeper. Differs from said species in pure white flanks (sub-species macrodactyla has faintly buff flanks but not as marked as in Short-toed), shorter and only moderately curved bill, hind-claw as long as hind-toe and "notched" wing-bar (uneven "steps"). Tips of primaries with buffish/white tips/fringes extending along inner web. Mostly distinguished from Short-toed by call, and identification exclusively by plumage characters difficult in areas where both species occur.
Sound:Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). Song a short, continuous three-part phrase. Each phrase starts with a few contact call-like notes followed by a Willow Warbler-like descending part, which then jumps to a few descending high notes to form a marked conclusion. Note that "mixed singers" are not uncommon in areas where both species of treecreepers occur.
