A striking kingfisher with clean white underparts and collar and blue-green upperparts. Restricted to the Talaud Islands. Inhabits forest and forest edge away from the coast, often close to rivers and streams. Distinguished from Collared Kingfisher by being smaller, shorter-billed, and shorter-tailed, with a greener cast to the upperparts. Talaud Kingfisher is absent from the coastal areas to which Collared is restricted. Gives a raucous, repetitive “kee-kee-kee-kee…” call as well as a slower-paced, pulsating “kree-ow-kree-ow…”.
