s. The black-browed fulvetta, ''Alcippe grotei'', is sometimes considered to be conspecific with mountain fulvetta, but the two forms differ in morphology and vocalisations, and are separated altitudinally. Black-browed fulvetta occurs primarily below 400 m, and mountain fulvetta above 900 m. Both have a warm brown back and tail, whitish underparts, a grey face and a slate grey crown bordered below with a black line, but black-browed has brown flanks and a weaker white eyering. Mountain has a ''yi-yuii-uwee-uwee'' song, whereas black-browed's is ''yu-chi-chiwi-chuwoo, yu-uwit-ii-uwoo''.
