Муравьиный москитолов Corythopis delalandi

Medium-sized odd-looking, ground-walking flycatcher of humid forests and second growth. Unmistakable in most of its range with its olive-brown back, yellow bill, white face and belly, and black breast. Told from Ringed Antpipit, for which there is barely any distributional overlap, by being paler and less olive above with a creamier chin and throat. Generally shy but its song is very distinct: a melodic series of explosive “preeeh-prrrwee-prurr-prii” notes. Also makes loud bill-snapping noises.
