The adult brown-throated wattle-eye is a stout bird about 14 cm (5.5 in) long. The breeding male has glossy black upperparts, and white underparts with a neat black breast band. There is a strong white wingbar, and fleshy red wattles above the eye.
The females are grey-black above, and also have the white wing bar and red wattles. There is a small patch of white below the bill, and the throat and breast are maroon, separated from the white belly by the black breast band. Young males are washed-out, greyer versions of the female.
These active insect-eating birds are found in pairs or small groups. The ringing call of the brown-throated wattle-eye is a very characteristic six note doo-dd-dum-di-do-do.
