Often considered conspecific with C. merulinus, as their “songs… are the same, their juvenile plumages are similar, and the host species of passerinus appear to be the same as for races querulus and merulinus, indicating a similar ecological role too”. Subsequent consideration of acoustic and other evidence, however, indicates that passerinus is a separate species on account of all slaty-grey underparts vs yellowish-grey throat and breast switching to dull rufous belly (3); whitish-grey vs dull rufous thighs, vent and underwing-coverts (3); strongly different songs#R#R (assume 3); moreover, a narrow hybrid zone exists (2). Monotypic.
