The little swift (Apus affinis) is a small species of swift found in Africa and southwestern Asia, and are vagrants and local breeders in southern Europe. They are found both in urban areas and at rocky cliffs where they build nests in a way typical of all members of the order Apodiformes. The genus name Apus is Latin for a swift, thought by the ancients to be a type of swallow without feet (from Ancient Greek α, a, "without", and πούς, pous, "foot"). The Latin specific affinis means similar to or related to, but in this case the species that the little swift supposedly resembles is not clear from the description. A population formerly considered to be an eastern subspecies of little swift is now separated as a distinct species, the house swift (Apus nipalensis).
Little swifts are readily identified by their small size. Their wingspan is only 33 cm compared to 42 cm in the case of common swift. Their plumage is black except for a white throat and rump, the white rump patch extending onto the flanks. They have a short square tail, with all rectrices round-tipped. The flight is fluttering like that of a house martin, and the call is a high twittering. Like other swifts... Wikipedia →
With luck
About 10% of wildlife watchers report a Little Swift sighting in Harare on a given day, based on 89 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 213 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
November to March
In those months about 20% of wildlife watchers report a Little Swift in Harare on a given day, against under 5% in May and August, the lowest months. Those are among Harare's wettest months, with about 140 mm of rain a month against almost none in August.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Little Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
50th of 98
Of the 98 cities where we can rate Little Swift sightings, Harare ranks 50th at about 10%. The best odds are in Abuja (Nigeria, about 70%), Brazzaville (Republic of the Congo, about 60%) and Marrakesh (Morocco, about 60%).
GBIF citizen-science records
It is estimated from how often the Little Swift is recorded against all the birds logged in Harare (89 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.
