"Red-fronted Tinkerbird Pogoniulus uropygialis is split into Northern Red-fronted Tinkerbird Pogoniulus uropygialis and Southern Red-fronted Tinkerbird Pogoniulus pusillus. These two species are widely separated in range, with a large gap between the range of Southern (Southern Africa north to far southern Mozambique) and Northern (East Africa south to southern Tanzania). Although these two species look similar, they differ vocally and do have subtle face pattern differences, with whiter throat and eyebrow in the northern bird (more yellow in the south) and a golden cast to the wing marking in the south (vs. yellow in the north). Habitat also differs, with Southern being a bird of tall forest and Northern preferring lower Acacia scrub."
