Cassin's hawk-eagle (Aquila africana) or Cassin's eagle, is a relatively small eagle in the family Accipitridae. Its feathered legs mark it as member of the Aquilinae or booted eagle subfamily. A forest-dependent species, it occurs in primary rainforests across western, central and (marginally) eastern Africa where it preys on birds and tree squirrels. It was named after John Cassin who first described it in 1865. Due to widespread habitat destruction, its populations are steadily declining but have not yet warranted upgrading its status from Least Concern.
The adult Cassin's hawk-eagle appears as a small eagle, with short rounded wings and a long rounded tail. It has dark brown upperparts, with white spots and a brown tail with three black bars and a broad black subterminal band. The tarsi are white with black streaks, and the underparts are all white or white with black blotches along the sides of the lower breast. It has yellowish-brown eyes, pale yellow ceres and feet and a black bill. Immature and juvenile plumage is strikingly different from that of adults. A brown or rufous head with dusky lores and streaked black on the throat and centre of the crown is typical... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cassin's Hawk-Eagle sighting in Semuliki National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 280 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.
August
In that month about 20% of wildlife watchers report a Cassin's Hawk-Eagle in Semuliki National Park on a given day, against under 5% in September to July, the lowest months. That is one of Semuliki National Park's wettest months, with about 120 mm of rain against 5 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cassin's Hawk-Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Cassin's Hawk-Eagle sightings, Semuliki National Park ranks 3rd at under 5%. The best odds are in Nyungwe National Park (Rwanda, about 10%) and Bwindi Impenetrable National Park (Uganda, under 5%).
Same family: Accipitridae
The closest relatives of the Cassin's Hawk-Eagle that you can see in Semuliki National Park (family Accipitridae, Hawks, Eagles, and Kites) are Palmnut Vulture (about 70%), African Fish-Eagle (about 20%) and African Harrier-Hawk (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cassin's Hawk-Eagle is recorded against all the birds logged in Semuliki National Park (13 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.
