A tiny kingfisher of lowland and foothill forest interior. Deep, cobalt blue head and wings with eye-catching paler blue patch on the back and pale orange belly. White throat and ear patch, with pale buff spot behind the bill. Flies overhead like a blue, speeding bullet. Devilishly difficult to see. Similar to Azure Kingfisher, but Papuan Dwarf-Kingfisher is smaller, lacks the blue on the sides of the chest and isn’t associated with water. Voice, high-pitched “cheep!” calls.
