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.

With luck
About 10% of wildlife watchers report a Southern Gray-headed Sparrow sighting in Durban on a given day, based on 136 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Southern Gray-headed Sparrow in Durban on a given day, against under 5% in June, the lowest month. That is one of Durban's wettest months, with about 210 mm of rain against 25 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Southern Gray-headed Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 8
Of the 8 cities where we can rate Southern Gray-headed Sparrow sightings, Durban ranks 5th at about 10%. The best odds are in Harare (Zimbabwe, about 50%), Pretoria (South Africa, about 40%) and Johannesburg (South Africa, about 20%).
GBIF citizen-science records
It is estimated from how often the Southern Gray-headed Sparrow is recorded against all the birds logged in Durban (136 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.
