The black-chested snake eagle or black-breasted snake eagle (Circaetus pectoralis) is a large African bird of prey of the family Accipitridae. It resembles other snake eagles and was formerly considered conspecific with the short-toed and Beaudouin's snake eagles, to which it is closely related.
Although originally proposed as separate species, many authors previously considered both the black-chested and Beaudouin's snake eagles to be subspecies of the short-toed snake eagle (Circaetus gallicus). However, this convention was not followed by all taxonomists, with some citing differences in adult plumage and breeding ranges as evidence in favour of awarding each full species status. Brown (1974) followed this latter view, but cited several instances of alleged hybridization between the three forms which would justify their treatment as a single species under the Biological Species Concept. However, Clark (1999) suggested that these alleged hybridization events may have instead resulted from misidentification of juvenile or subadult black-chested snake eagles as adults of other species.

Rare
Under 5% of wildlife watchers report a Black-breasted Snake Eagle sighting in Bwindi Impenetrable National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 366th most-seen of the 400 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-breasted Snake Eagle in Bwindi Impenetrable National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-breasted Snake 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.
41st of 41
Of the 41 parks where we can rate Black-breasted Snake Eagle sightings, Bwindi Impenetrable National Park ranks 41st at under 5%. The best odds are in Kgalagadi Transfrontier Park (South Africa, about 30%), Masai Mara National Reserve (Kenya, about 20%) and Serengeti National Park (Tanzania, about 20%).
Same family: Accipitridae
The closest relatives of the Black-breasted Snake Eagle that you can see in Bwindi Impenetrable National Park (family Accipitridae, Hawks, Eagles, and Kites) are Augur Buzzard (about 20%), African Harrier-Hawk (about 10%) and Mountain Buzzard (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-breasted Snake Eagle is recorded against all the birds logged in Bwindi Impenetrable National Park (6 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.
