Hitherto treated as conspecific with M. olivaceus, but differs in characters given under that species. Songs of nominate and hederaceus are distinguishable from each other and differ rather strongly from those of other two races, which sound very similar (apart from rather different population of venezuelensis in Caripe, which may indicate an undescribed taxon); thus, at least one further species may be involved. Populations vary morphologically along two N–S clines, one from WC Panama to W Ecuador and the other following E base of mountains from NE Venezuela and Trinidad S to Bolivia; proposed race improvisus (N Cauca Valley) merged with hederaceus, as intermediate within W cline; pallidus (E Andes of Colombia in Magdalena and N Meta) and meridae (NW Venezuela and adjacent NE Colombia) are indistinct, intermediate forms within E cline, both treated as synonyms of venezuelensis. Four subspecies recognized.
