The white-headed mousebird (Colius leucocephalus) is a bird belonging to the mousebird family, Coliidae. It is found only in east Africa where it occurs in southern Somalia and parts of Kenya with its range just extending into southern Ethiopia and northern Tanzania. It inhabits arid bushland up to 1,400 metres above sea-level.
It is 32 cm long with the long, graduated tail accounting for over half of this. The plumage is mainly greyish with black and white barring on the back, neck and breast. It has a white crest, crown and cheeks. There is a white stripe down the back which becomes visible when the bird flies. Around the eye is a patch of dark, bare skin. The bill is bluish-white above and buff below. In juvenile birds, the throat and breast are buff.
The contact call is a scratchy chattering and the bird also has a descending song. Sinclair, Ian & Ryan, Peter (2003) Birds of Africa south of the Sahara, Struik, Cape Town.

Possible
About 20% of wildlife watchers report a White-headed Mousebird sighting in Mkomazi National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 127th most-seen of the 272 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a White-headed Mousebird in Mkomazi National Park on a given day, against under 5% in November, the lowest month. That is one of Mkomazi National Park's driest months, with about 20 mm of rain against 150 mm in December. May has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-headed Mousebird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 7
Of the 7 parks where we can rate White-headed Mousebird sightings, Mkomazi National Park ranks 2nd at about 20%. The best odds are in Samburu National Reserve (Kenya, about 50%).
GBIF citizen-science records
It is estimated from how often the White-headed Mousebird is recorded against all the birds logged in Mkomazi National Park (25 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.
