The Yellowish Imperial-pigeon (Ducula subflavescens), also known as the Bismarck Imperial-pigeon (leading to easy confusion with D. melanochroa), is a relatively large species of bird in the Columbidae family. It is endemic to forest and woodland in the Bismarck Archipelago. It is threatened by habitat loss.
It is often considered a subspecies of the Torresian Imperial-pigeon (which in turn sometimes is considered a subspecies of the Pied Imperial-pigeon), but is increasingly treated as a separate species. It resembles the Torresian Imperial-pigeon, but has a distinctly yellow-tinged plumage and a bluish base to the bill.
