The African Dusky Flycatcher, Dusky-brown Flycatcher, Muscicapa adusta, is a small passerine bird of the Old World flycatcher family, Muscicapidae. It is a resident breeder in Africa from Nigeria, the Central African Republic, Sudan and Ethiopia south to South Africa. It is very common in its woodland habitat, which includes riverine forests, evergreen forest edges and clearings, especially near water bodies such as lakes, dams and streams, and well-wooded suburban gardens.
Its upperparts are plain brown, with the only facial marking being an indistinct narrow eye-ring. The chin is plain pale grey, and the rest of the underparts are grey-brown with indistinct streaks. The short, straight, laterally flattened bill is black, the legs and feet are grey, and the eyes are brown.
The African dusky flycatcher has soft, high-pitched "tzeeet" and tsirit calls.
This species is monogamous, mating for life.
The African dusky flycatcher is usually seen singly or in pairs. It forages from an open perch for insects typically taking its prey in a short flight.
