Wahlberg's eagle (Hieraaetus wahlbergi) is a bird of prey that is native to sub-Saharan Africa, where it is a seasonal migrant in the woodlands and savannas. It is named after the Swedish naturalist Johan August Wahlberg. Like all eagles, it belongs to the family Accipitridae.
Wahlberg's eagle is a medium-sized raptor, and the sexes are similar. It is about 53–61 cm (21–24 in) in length with a wingspan of 130–146 cm (51–57 in) and a body mass of 437–845 g (15.4–29.8 oz) for males and 670–1,400 g (24–49 oz) for females on average. The head has a small crest, and the legs are yellow. The plumage tone is variable but may be dark brown except for dark-streaked grey undersides to the flight feathers, and a barred grey undertail. Light and dark plumage phases occur. A pale variant may be much lighter brown with whitish, rather than grey undertail and flight feather undersides. The pale variant is much less common than the darker variant.
Wahlberg's eagle is distributed from central Chad to the north-east coast of South Africa. Its western boundary is thought to be Cameroon, although it most commonly occurs further east across the continent... Wikipedia →
With luck
About 10% of wildlife watchers report a Wahlberg's Eagle sighting in Kigali on a given day, based on 96 verified sightings from GBIF citizen-science data. It is the 102nd most-seen of the 244 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March, May, July–September and November–January
In those months about 10% of wildlife watchers report a Wahlberg's Eagle in Kigali on a given day, against under 5% in February, April, June and October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Wahlberg's Eagle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Wahlberg's Eagle sightings, Kigali has the highest daily chance: about 10%. Next come Kampala (Uganda, about 10%) and Addis Ababa (Ethiopia, under 5%).
GBIF citizen-science records
It is estimated from how often the Wahlberg's Eagle is recorded against all the birds logged in Kigali (96 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.
