The white-backed mousebird (Colius colius) is a large species of mousebird. It is distributed in western and central regions of southern Africa from Namibia and southern Botswana eastwards to Central Transvaal and the eastern Cape.
This mousebird prefers scrubby dry habitats, such as thornveld, fynbos scrub and semi-desert. This bird is about 34 cm (13.5 in) long, with the tail comprising approximately half the length, and weighs 38–64 g (1.3–2.3 oz). The upper parts, head, prominent crest and breast are grey apart from a white back stripe flanked by two broad black stripes and a dark red, or maroon, transverse band at the base of the tail. The white is not visible unless the wings are at least partly open, such as when the birds are alighting, or sometimes in hot weather. The belly is buff in colour. The bill is bluish white with a black tip, and the legs and feet are red.
The speckled mousebird can be distinguished from this species by its differently coloured beak, legs and upperparts. The white-backed mousebird has a whistled zwee-wewit call. It also has a buzzing or crackling call that might be for alarm or keeping in contact with the group.

Rare
Under 5% of wildlife watchers report a White-backed Mousebird sighting in Johannesburg on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 185th most-seen of the 219 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-backed Mousebird in Johannesburg on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-backed Mousebird sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate White-backed Mousebird sightings, Johannesburg ranks 2nd at under 5%. The best odds are in Cape Town (South Africa, about 20%).
GBIF citizen-science records
It is estimated from how often the White-backed Mousebird is recorded against all the birds logged in Johannesburg (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
