Cetti's Warbler (Cettia cetti)
Treecreeper (Certhia familiaris)
Small, warm buff warbler with skulking behaviour, but conspicuous song. Similar in size to Reed Warbler, but with short, rounded wings and rounded tail. Build fairly compact, but bill thin and slender. Supercilium thin and dull. Cheeks and underparts greyish white, lacking the purer white belly of confusion species. Pale eye-ring. Under tail-coverts usually brown with pale fringes. Often flicks tail or holds it raised. Usually hides among undergrowth, and shows itself only when moving from one shrub to another.
Sound:Contact call a short, metallic, ascending "vitt". Often given in rapid series. Song diagnostic, and readily given throughout the year. Phrases last from 2 - 5 seconds, consisting of a few loud, clear and rapid glissandi, given in approximately same register. E.g. "cetti cetti cetti", usually with a few introductory notes, and some variation to the phrase. Overall a very explosive, and with a staccato rhythm.

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.
