Clearly very closely related to D. bicolor (which see), D. subflavescens and D. luctuosa; the notion that yellow bill is a constant character of present species is not borne out by museum material, which describes bills as “blue slate”, “slate-blue”, “greenish-slate, yellow tip”, “olive-yellow”, “yellow”, “yellow, cere battleship grey”, etc., suggesting perhaps an age-related or seasonal condition. Often united with D. subflavescens but differs on account of its white vs yellowish plumage (3), grey-tinged vs black primary underwing-coverts (2), and narrower black tips of outer tail (2)#R. Proposed races include tarara (SC New Guinea) and melvillensis (Melville I) but these forms are confused by intergradation. Proposed form constans (Kimberley region of NW Australia) has even been considered a separate species, but is not widely accepted; herein provisionally not recognized at any level, pending further work. Monotypic.

Distribution:

Aru Is, and coastal New Guinea (penetrating inland along some major rivers) and islands in Geelvink Bay E to D’Entrecasteaux Archipelago, Trobriand Is, Woodlark Is and Louisiade Archipelago, then S to N & NE Australia (Kimberley region and NW Northern Territory E to N & C Cape York Peninsula, and S down E Queensland coast to Aquila I, near Carmila).
