Appearance:

Male with shiny black upperparts and pure white underparts. Female grey-brown with pale underparts. Both sexes with broad white edges to tertials and greater coverts, forming a broad white patch (largest in males). Fairly compact body compared to Spotted Flycatcher, with shorter tail and bill. Easily confused with Collared- and Semicollared Flycatcher where these occur. Both sexes differs from Semicollared in no white edges to end of tail and less white at base. Distinguished from Collared in white patch beneath alula being narrow and not reaching edge of wing (both sexes), white base of tail (black in Collared males) and no collar (males).

Sound:

Alarm call a sharp, energetic "wit", often in combination with a short "tic"; "whit-tic". Song a pleasant, tuneful, simple but varied phrase. Typically starts with disyllabic notes being repeated 3-5 times, diminishing in pitch and intensity like an echo of the first two syllables. Occasionally throws in a quick diagnostic ascending scale excercise. Clear notes and well defined pauses between phrases.
