The African Dusky Flycatcher inhabits forests (mainly edges and clearings), riverine woodland and densely planted parks and gardens, and is easily overlooked. They feed mainly on flying insects but do include a little fruit in their diet on occasion. They are small birds, weighing about 11g as adults and measuring around 13cm in length.
Pairs of the African Dusky Flycatcher are monogamous and build their cup-shaped nests in holes in trees or crevices in rocks using fine plant material, feathers and spider webs. Their breeding season spans spring and summer, and only the female incubates the clutch of 2 or 3 eggs over a 2-week period while the male brings food to her at the nest. The chicks become independent within 3 weeks of hatching, often allowing the parents to raise another brood in the same season.
While noting that their populations are probably declining due to habitat destruction, the IUCN lists the African Dusky Flycatcher as being of least concern. The species is distributed patchily from east and central Africa south to South Africa, where they occur throughout our wetter eastern and southern provinces.
