The southern grey-headed sparrow (Passer diffusus) is a passerine bird of the sparrow family Passeridae. It is sometimes treated as a subspecies of the grey-headed sparrow. It is found in savanna and woodland in Angola and Zambia southwards into South Africa, where it is expanding its range and is kept as a caged bird, like its relative the white-rumped seedeater.

Possible
About 20% of wildlife watchers report a Southern Gray-headed Sparrow sighting in Johannesburg on a given day, based on 863 verified sightings from GBIF citizen-science data. It is the 32nd most-seen of the 219 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
November to February
In those months about 30% of wildlife watchers report a Southern Gray-headed Sparrow in Johannesburg on a given day, against about 20% in March to October, the lowest months. Those are among Johannesburg's wettest months, with about 110 mm of rain a month against almost none in July.

GBIF citizen-science records
It is estimated from how often the Southern Gray-headed Sparrow is recorded against all the birds logged in Johannesburg (863 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.
