The Swahili sparrow (Passer suahelicus) is a passerine bird of the sparrow family Passeridae. It lives in the savanna of southern Kenya and Tanzania. Until recently, it was usually treated as a subspecies of the northern grey-headed sparrow (Passer griseus), with which it hybridizes in southern Tanzania and possibly elsewhere. It has a more rounded head profile however, a smaller eye and the grey head plumage extends unto the mantle.
In addition to the subtle physical characteristics, the Swahili sparrow also differs from the northern grey-headed sparrow in terms of habitat preference, nest construction and post-breeding behaviour. They build grass nests in Acacia trees in dry regions, and generally avoid moister coastal lowlands or uplands. Following the breeding season they form nomadic flocks, and the bill colour will change from black to horn-coloured. They may nest in the proximity of northern grey-headed sparrow, but not on buildings, and may be found beside individuals of the latter species as they disperse onto farmland.

Possible
About 30% of wildlife watchers report a Swahili Sparrow sighting in Tarangire National Park on a given day, based on 512 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 57th most-seen of the 411 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March and April
In those months about 50% of wildlife watchers report a Swahili Sparrow in Tarangire National Park on a given day, against about 20% in January, May and August–September, the lowest months. Those are among Tarangire National Park's wettest months, with about 140 mm of rain a month against almost none in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Swahili Sparrow sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 7
Of the 7 parks where we can rate Swahili Sparrow sightings, Tarangire National Park ranks 2nd at about 30%. The best odds are in Ruaha National Park (Tanzania, about 40%).
Same genus: Passer
The closest relatives of the Swahili Sparrow that you can see in Tarangire National Park (genus Passer, True Sparrows) are Northern Grey-headed Sparrow (about 20%) and Chestnut Sparrow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swahili Sparrow is recorded against all the birds logged in Tarangire National Park (512 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.
