Restricted to 7 forested mountain areas in Mozambique, Zimbabwe, and Tanzania, where it mainly occurs from around 1,200 m to 1,700 m elevation, but sometimes as low as 800 m up to 1,850 m. A significant exception is the population in East Usambara Mountains in Tanzania, where it is found only in lowland forest at 130–550 m. It is known from the following mountain areas:

Mt. Selinda, eastern Zimbabwe. Recorded from Chirinda Forest (type-locality) at 900–1,300 m (14, 15, 16).

Bvumba (Vumba) Highlands, eastern Zimbabwe. In several forest patches in this highland, including Seldomseen and Vumba Gardens, at 1,200–1,850 m (1, 16, 3; C. Chirara, in litt. 2012 in 17).

Mt. Rupere, eastern Zimbabwe. From 1,400–1,700 m in Stableford Forest (18, 19; A. Manson, in litt. in 20, 16).

Mt. Gorongosa, central Mozambique. The forest on this isolated mountain previously supported a large population, which ranged from 850 m to 1,750 m (21; J. Burlison, in litt. in 20). Status now uncertain as forest above 1,100 m was found to be much reduced in 2007 (22), but Swynnerton’s Robin was still present in 2011, when recorded by a Field Museum (Chicago) expedition (Mozambique Expedition 2011).

Mt. Mabu, northern Mozambique. Small population discovered in 2008, occurring from around 1,340 m to the upper limits of forest at 1,600–1,650 m (23).

Udzungwa Mountains, central Tanzania. Widespread in forests in this large mountain area; recorded from Ndundulu-Luhombero, Nyumbanitu, Mwanihana, Ukami, Iyondo, and Uzungwa Scarp forests most frequent between 1,350 m and near 1,500 m, but sometimes as low as 800 m and up to at least 1,850 m in the northern part of Uzungwa Scarp (24, 25; FPJ, unpublished data).

East Usambara Mountains, northeastern Tanzania. First recorded in 1990 and now known from several lowland forest patches in the East Usambara foothills (Mtai, Longuza, Segoma, Manga, Kambai, Marimba, and Kwamgumi Forest Reserves) at 130–550 m (26, 4, 27).
