Circaetinae

Circaetinae is a subfamily of birds of prey in the family Accipitridae, commonly known as snake eagles. These eagles are found in the Old World, primarily in Africa and southern Asia. They are characterized by their specialized diet, feeding almost exclusively on snakes, although they may also consume lizards and other reptiles.

Members of the Circaetinae subfamily are typically medium to large-sized eagles. They possess strong talons adapted for grasping slippery prey and keen eyesight to spot reptiles from a distance. Their plumage varies, but often includes cryptic coloration that aids in camouflage within their habitats, which range from open woodlands and savannas to more arid regions.

A notable feature of Circaetinae is their remarkable resistance to venom. While not entirely immune, they can withstand the venom of many snakes, allowing them to hunt and consume even the most venomous species. This adaptation is crucial for their survival and dietary specialization.

Several genera are recognized within Circaetinae, including Circaetus, Spilornis, Dryotriorchis, and Eutriorchis. The snake eagles are an important part of their respective ecosystems, helping to regulate reptile populations. Their conservation status varies, with some species facing threats from habitat loss and persecution.
