Smaragðsbreiðnefja Calyptomena whiteheadi

Magnificent emerald-green giant of a broadbill, with distinctive black mottling and streaking. Males have black streaking on the underparts which females lack. A specialty of Borneo’s central highlands, where it can be found in montane forest with extensive tall pristine growth. Typically seen singly, but occasionally also in pairs or small flocks, especially at fruiting trees. Gives a sharp metallic “tlak!”, followed by a grating rattle.
