Snow Bunting (Plectrophenax nivalis)
Treecreeper (Certhia familiaris)
Easily recognized bunting with highly contrasting plumage. Tail with black center, boldly framed by white edges and white rump in all plumages. Males with white wings with black hand. Adult females with most inner parts of wings white, juveniles with white wing-bars only. A flock usually has a few adult males which gives away the species with their flashing white wings. Summer plumage of male white with black back, bill and legs. Female less pure white, with buffish head and cheeks. Juveniles mostly grey. Though most of adults white on wing is missing, the tail-pattern is diagnostic in flight also in young birds. In winter plumage the black parts of the plumage turn more brown and buff in both sexes.
Sound:Contact call a short, melodic and rapidly descending "peeuu". Often alternating with a rattling "trrreet". "Peeuu"-call quite similar to Lapland Bunting, but harder, purer in tone and less nasal. Song simple and melodic. 2-5 syllable motifs with fairly wide tonal range. Can be confused with Lapland Bunting, but is much purer in tone with a less jingling timbre. Local dialects.

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.
