Amber Mountain, north Madagascar

See M. imerina. Often considered conspecific with M. sharpei, and recent molecular studies all argue for this based on low genetic divergence#R#R#R; however, differs markedly in morphology, having breast rich orange-rufous vs dull blue-grey (i.e. transition in colour is at lower throat; 3); rich blue-grey crown to nape sharply demarcated from dark chestnut-brown back to rump and scapulars vs duller (olive-tinged) blue-grey crown gently grading to dark grey-tinged olive-brownish back to rump (3); and larger size (effect size for both bill and wing in males 2.13; score 2); female mirrors male breast pattern by replacing long pale and dark streaks of M. sharpei with rusty breastband and broad straw-coloured streaks (ns). Monotypic.

Distribution:

Montagne d’Ambre (Mt Amber), in N Madagascar.
