d’Orbigny and Lafresnaye, 1837,
Closely related to M. olivaceus. Proposed race poliocephalus (Pasco and Junín, in C Peru) merged with nominate, as it occupies indistinct zone of intergradation between subspecifically recognizable plumage patterns of N & S Peru; similarly, selvae (W Andes of Colombia) merged with columbianus, population in question occupying zone of diffuse intergradation between grey-crowned columbianus and green-crowned viridiceps. Four subspecies recognized.
