A striking medium-sized kingfisher of lowland and foothill forest. Whitish below with dark scaling and dark green above with buff spotting. Bill bicolored, black above and orange below. Note the broad black band through the eye, reaching the back of the head, and the green crown and rump. Male has a full rufous collar, throat, and band below the eye, as well as a bright blue moustache and band behind the eye that are green in the female. Unmistakable in its range. Song, given at dawn, consists of a single downslurred whistle, “wee-ooo,” repeated every few seconds.
