Great Reed Warbler (Acrocephalus arundinaceus)
Short-toed Treecreeper (Certhia brachydactyla)
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
Very similar to Treecreeper C. familiaris, and id by sound generally easier than by appearance in areas where both species occur. Primaries with small, almost pure white tips restricted to outer web. Hind-claw shorter than hind-toe. Wing-bar usually with even "steps", but often difficult to determine. Underparts less white and more brownish than in continental C. familiaris (which again is browner than the pure white northern subspecies). Bill longer and with a stronger curved tip.
Sound:Contact call very similar to C. familiaris. A thin "sreee" often repeated in an even rhythm, perhaps with slighly shorter pauses. Flight call a short and sharp "wit" used freely when moving about. Song diagnostic, and introductory notes often used singly when interacting. Full song starts with one or two staccato introductory notes, the first higher pitched than the second, followed by a rapid, ascending crescendo ending in a drawn-out, less pure "sree". The tone is loud and much more penetrating and clear than C. familiaris. Timbre recalls wet rubber-boots on vinyl flooring. Note that "mixed singers" of C. familiaris are not uncommon in areas where both species of treecreepers occur.
