, 1882,



Until recently treated as a race of M. castaneiventris (and always as conspecific with M. megarhynchus), but genetically#R, morphologically and vocally distinct. Differs from geographically, genetically and morphologically closest form M. megarhynchus in its all-black underparts (3); slightly larger size, with longer bill (effect size 2.08, score 2); three-note phrase vs single whistle (3) or single whistle-length (ns[3]); and different call (1)#R. Monotypic.

What do (1) and (2) mean? Learn more about the scoring system.
