Usually treated as conspecific with P. collybita, but differs in its almost total replacement of yellow in plumage with buffy grey-brown, with no olive in crown or mantle (1); blacker bill and legs (1); buff-washed pale supercilium (ns); distinctive call and song, latter having a faster pace (at least 2), narrower frequency range of notes (3), lower maximum frequency (ns[2]), and many more different note shapes including overslurred and rising notes (ns[2])#R. Broad intergradation with P. c. abietinus in W of range, as reported in HBW, poorly documented, with contradictory distributional evidence; research in progress, with recent suggestion that hybrid zone may be only 10 km wide#R. Name fulvescens proposed for seeming intergrades from (roughly) R Pechora to R Yenisey, but birds in question sing like present species, resulting in name being synonymized, although plumage has variable degrees of yellow; situation further confused by presumed P. collybita in Middle East and Caucasus reported as giving calls like those of present species; research required. Monotypic.
