Pigeons and Doves (Columbidae)

White Imperial-pigeon (Ducula luctuosa) - HBW 4, p. 241

French: Carpophage luctuose German: Elsterfruchttaube Spanish: Dúcula Luctuosa
Other common names: Sulawesi Pied/Celebes Pied/Silver-tipped Imperial-pigeon, Nutmeg Pigeon, White Fruit-pigeon

Taxonomy: Columba luctuosa Temminck, 1825, Sulawesi.
Forms a distinctive superspecies with D. bicolor and D. spilorrhoa; species limits in this group are unclear, and all three sometimes considered conspecific; other authors recognize up to five species; further study required. Range apparently overlaps with that of D. bicolor in N & C Sulawesi (e.g. Gorontalo, Bumbulan), where the two are segregated by habitat preferences. Monotypic.

Distribution: Sulawesi and islands off NE (Manadotua, Manterawu, Talisei, Bangka, Lembeh) and SE (Muna, Labuan Blanda, Butung) to Banggai and Sula Is.
