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.

Likely
About 60% of wildlife watchers report a White-backed Mousebird sighting in West Coast National Park on a given day, based on 902 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 192 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
June and July
In those months about 80% of wildlife watchers report a White-backed Mousebird in West Coast National Park on a given day, against about 50% in December, the lowest month. Those are among West Coast National Park's wettest months, with about 65 mm of rain a month against 5 mm in February.
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.
Yes
Of the 9 parks where we can rate White-backed Mousebird sightings, West Coast National Park has the highest daily chance: about 60%. Next come Namib-Naukluft National Park (Namibia, about 30%) and Kgalagadi Transfrontier Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the White-backed Mousebird is recorded against all the birds logged in West Coast National Park (902 verified sightings from 2019 to 2026), 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.
