There are five species of brown snake eagles in the world, all belonging to the genus Circaetus in the family Accipitridae. These majestic birds of prey are specialized hunters, feeding primarily on snakes and other reptiles. Let’s dive into the details of these five fascinating brown snake eagle species.
The 5 Species of Brown Snake Eagles
- Short-toed Snake-eagle (Circaetus gallicus)
- Black-chested Snake-eagle (Circaetus pectoralis)
- Beaudouin’s Snake-eagle (Circaetus beaudouini)
- Brown Snake-eagle (Circaetus cinereus)
- Southern Banded Snake-eagle or Fasciated Snake-eagle (Circaetus fasciolatus)
Short-toed Snake-eagle (Circaetus gallicus)
The Short-toed Snake-eagle is the only migratory species among the brown snake eagles. It breeds in the Mediterranean basin and winters in sub-Saharan Africa and as far east as Indonesia. These eagles are known for their distinctive short, thick toes, which help them grasp and subdue their slithering prey.
Black-chested Snake-eagle (Circaetus pectoralis)
The Black-chested Snake-eagle is found in eastern and southern Africa, from Ethiopia to South Africa. These eagles have a striking black chest and belly, which contrasts with their pale gray upper parts. They are skilled hunters, using their keen eyesight to spot snakes and other reptiles from a distance.
Beaudouin’s Snake-eagle (Circaetus beaudouini)
Beaudouin’s Snake-eagle is a rare and localized species found in parts of West and Central Africa. These eagles have a distinctive dark head and neck, with a pale gray body and wings. They are considered Near Threatened due to habitat loss and hunting pressure in their limited range.
Brown Snake-eagle (Circaetus cinereus)
The Brown Snake-eagle is the most widely distributed of the five species, found throughout much of sub-Saharan Africa. These eagles are known for their large size, with a wingspan that can reach up to 1.8 meters. They are skilled hunters, using their powerful talons to capture and kill snakes and other reptiles.
Southern Banded Snake-eagle (Circaetus fasciolatus)
Also known as the Fasciated Snake-eagle, this species is found in parts of southern Africa, including South Africa, Mozambique, and Zimbabwe. These eagles have a distinctive banded pattern on their wings and tail, which helps them blend in with the dappled light of their woodland habitats.
Habitat and Behavior

All five species of brown snake eagles share a similar habitat preference, preferring open habitats like cultivated plains, arid savannas, and lightly wooded areas. They require trees in which to build their large stick nests, as they are not adapted to nesting on the ground.
These eagles are specialized predators, with heavy scaling on their tarsi (lower legs) to protect them from snake bites. They use their keen eyesight to spot their prey from a distance, often soaring high above the ground before swooping down to capture a snake or other reptile.
Conservation Status
The conservation status of the brown snake eagles varies across the different species. The Brown Snake-eagle is categorized as a species of Least Concern by the IUCN, but it is considered uncommon in most areas, and habitat destruction is likely having a negative effect on this species.
The Beaudouin’s Snake-eagle is considered Near Threatened, while the Southern Banded Snake-eagle is listed as Vulnerable due to habitat loss and hunting pressure within its limited range.
Ongoing efforts to protect the habitats of these remarkable birds of prey, as well as to reduce hunting and persecution, are crucial to ensuring the long-term survival of the brown snake eagle species.
Conclusion
The five species of brown snake eagles are fascinating and specialized predators, each with its own unique adaptations and characteristics. From the migratory Short-toed Snake-eagle to the rare and localized Beaudouin’s Snake-eagle, these birds play a vital role in the ecosystems they inhabit. By understanding and protecting these remarkable raptors, we can ensure that they continue to thrive in the years to come.
