A small flycatcher found in the midstory of both wooded and bamboo forests in lowland and hill regions. Male is dazzling sapphire-blue with a dirty-white belly; lack of other markings or warm coloration distinguishes it from other flycatchers. Female is brown with a pale orange throat and chest. Often joins mixed flocks. Song is a short but pleasant series of throatily warbled whistles, typically a burst of ascending notes, followed by one or two falling notes, then a final rising whistle. Call is sharp “tsik-tsik-tsik”, akin to scissors snipping.
