A spectacular medium-sized kingfisher of foothill and montane forest on Mindanao with a thick red bill, a white throat, a blue rump, and faintly scaled rufous on the underparts and cheek, extending around the back of the neck. The male has a blue crown, blue tail, and blue wings with buff spots. The blue is replaced by green in the female. The male also has an additional blue moustache stripe. Unmistakable. More often seen than heard. Song, given at dawn, consists of a single downslurred whistle with a slightly metallic quality, “wee-ooo,” repeated every few seconds.
