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.

Possible
About 30% of wildlife watchers report a Black-breasted Snake Eagle sighting in Kgalagadi Transfrontier Park on a given day, based on 192 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 36th most-seen of the 122 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September and November–March
In those months about 30% of wildlife watchers report a Black-breasted Snake Eagle in Kgalagadi Transfrontier Park on a given day, against about 10% in August, the lowest month. Those are among Kgalagadi Transfrontier Park's wettest months, with about 20 mm of rain a month against almost none in July. May has too few records to rate.
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.
Yes
Of the 41 parks where we can rate Black-breasted Snake Eagle sightings, Kgalagadi Transfrontier Park has the highest daily chance: about 30%. Next come Masai Mara National Reserve (Kenya, about 20%) and Serengeti National Park (Tanzania, about 20%).
GBIF citizen-science records
It is estimated from how often the Black-breasted Snake Eagle is recorded against all the birds logged in Kgalagadi Transfrontier Park (192 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.
