The white-billed buffalo weaver (Bubalornis albirostris) is a resident breeding bird species in most of Africa south of the Sahara Desert. This common weaver occurs in open country, especially cultivation and scrub. It is a communal breeder, building massive untidy stick nests in tree colonies, each of which may have several spherical woven nests within. Two to four eggs are laid.
The white-billed buffalo weaver is large and stocky, commonly measuring 23 to 24 centimeters. The adult is mainly black with white flecking on the back and wings. The conical bill is very thick, and appears more so because it is surmounted by a white frontal shield. The bill is white in breeding males.
The adult female and non-breeding male are similar, but the bill is black. Young birds are dark brown in plumage. The white-billed buffalo weaver is a gregarious species which feeds on grain and insects. This is a noisy bird, especially in colonies, with a range of cackles and squeaks.

Possible
About 20% of wildlife watchers report a White-billed Buffalo-Weaver sighting in Kidepo Valley National Park on a given day, based on 53 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 105th most-seen of the 332 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.

GBIF citizen-science records
It is estimated from how often the White-billed Buffalo-Weaver is recorded against all the birds logged in Kidepo Valley National Park (53 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.
