The '''mountain chiffchaff''' or '''eastern chiffchaff''' ('''''Phylloscopus sindianus''''') is a [[species]] of [[leaf warbler]] found in the [[Caucasus]] (''P. s. lorenzii'') and [[Tian Shan]] (''P. s. sindianus''). It is an altitudinal migrant, moving to lower levels in winter. The nominate subspecies is similar to the [[Siberian chiffchaff]], but with a finer darker bill, browner upperparts and buff flanks; its song is almost identical to the [[common chiffchaff]], but the call is a weak ''psew''. ''P. s. lorenzii'' is warmer and darker brown than the nominate race; it is [[Sympatric speciation|sympatric]] with common chiffchaff in a small area in the Western Caucasus, but interbreeding occurs rarely, if ever. The mountain chiffchaff differs from ''tristis'' in vocalisations, external morphology and [[mtDNA]] sequences. Its two subspecies appear to be distinct vocally, and also show some difference in mtDNA sequences.
