Great Reed Warbler (Acrocephalus arundinaceus)
Treecreeper (Certhia familiaris)
Large and bulky warbler with long tail, heavy, thrush-like bill and relatively strong facial markings. Supercilium broad and strong and continues behind eye. Lores dark. Primary projection same length as tertials. Flanks warm beige. Crest often raised. Flight heavy and jerky, and birds are also much more detectable by moving reeds when foraging about in vegetation than congeners. In the Middle East be aware of confusion species Clamorous Reed Warbler and Basra Reed Warbler.
Sound:Contact call a grating, dry "kirrrat", where each rolling r is discernable. Song similar to Reed Warbler in timbre, but much deeper and slower. Fairly concise motifs typically consisting of two deep mono- or disyllabic notes followed by a few higher tones. I.e: "kerek kerek, trii trii trii". Clamorous Reed Warbler differs in more diffuse motifs.

CCSound recording:Recorded by Edmunds Racinskis
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.
