The Horus swift (Apus horus) is a small bird in the swift family Apodidae that is found in sub-Saharan Africa. Horus, whose name this bird commemorates, was the ancient Egyptian god of the sun, son of Osiris and Isis. The Horus swift was formally described in 1869 by the German explorer and ornithologist Theodor von Heuglin under the binomial name Cypselus horus. The specific epithet is from Ancient Egyptian mythology: Horus was the god of the sun. This species is now one of 20 swifts placed in the genus Apus that was introduced in 1777 by the Italian naturalist Giovanni Antonio Scopoli. The species is treated as monotypic.
The Horus swift is 13–15 cm (5.1–5.9 in) long and quite bulky. It appears entirely blackish except for a white patch on the chin and a white rump. It has a medium length forked tail. It has a fluttering flight like little swift. The little swift has a square tail, and more extensive white on the rump than Horus, and white-rumped swift has a more deeply forked tail and a narrower white band... Wikipedia →

Rare
Under 5% of wildlife watchers report a Horus Swift sighting in Masai Mara National Reserve on a given day, based on 123 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 223rd most-seen of the 398 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April–May and November
In those months about 10% of wildlife watchers report a Horus Swift in Masai Mara National Reserve on a given day, against under 5% in June–October and December–March, the lowest months. Those are among Masai Mara National Reserve's wettest months, with about 110 mm of rain a month against 15 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Horus 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.
7th of 22
Of the 22 parks where we can rate Horus Swift sightings, Masai Mara National Reserve ranks 7th at under 5%. The best odds are in Arusha National Park (Tanzania, about 10%), South Luangwa National Park (Zambia, about 10%) and Mana Pools National Park (Zimbabwe, about 10%).
Same genus: Apus
The closest relatives of the Horus Swift that you can see in Masai Mara National Reserve (genus Apus, Typical Swifts) are Little Swift (about 20%) and White-rumped Swift (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Horus Swift is recorded against all the birds logged in Masai Mara National Reserve (123 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.
