Appearance:

Unmistakable, 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.

Appearance:

Unmistakable. Very small, mouselike bird with short rounded wings, short neck and upright tail. Upperparts chestnut brown and finely barred. Underparts light buff. Forages in thick undergrowth and low bushes, crevices and holes for insects. Easily overlooked, but betrays its presence by its big voice. One of the smallest bird in northern Europe.

Sound:

Song surprisingly loud. A high-pitched stream of clear notes resembling Robin and Dunnock in timbre. Differs from those in showing frequent shifts in pitch with much larger register than Dunnock, and by the unique, numerous, interspersed long trills. Warning call a short hard "teck", like banging two rocks together. Often repeated in series when excited to form machine-gun-like "firing".
