The Bismarck Whistler (Pachycephala citreogaster) is a striking, medium-sized songbird endemic to the Bismarck Archipelago. Males are instantly recognizable by their bold plumage: a glossy black head and breast band contrasting sharply with a white throat and bright lemon-yellow belly, complemented by an olive-green back and wings, and a short, stout bill.
