Largely all-blue flycatcher, with blue becoming intense on the forehead. Also note black face and pale, grayish belly. A bird of Sri Lanka’s hills and mountains, where it occurs as singles and pairs in the understory of dense, wet montane forest. Told from other largely blue songbirds, such as Tickell’s Blue Flycatcher and Black-naped Monarch, by combination of pale grayish belly and bold black marking between the bill and the eyes. Song comprises structured verses of rising and falling warbling notes, “chee-choo-choo-chewee-wee”. Also gives some short “chip” calls.
