The brown-streaked flycatcher (Muscicapa williamsoni) is a species of bird in the family Muscicapidae.It is found in southern Myanmar, southern Thailand, northern peninsular Malaysia, and northeast Borneo.[1] Some authorities consider it to be a subspecies of the Asian brown flycatcher. In 2020, a vagrant was sighted 300km (200miles) south of the Australian town of Broome and its identity was confirmed from DNA analysis from the droppings of the bird.[2] The species has a rufescent plumage in the breeding season and then becomes drab.[3] The species name is after the collector Sir Walter James Franklin Williamson.
