Circaetinae
Template:Short description Template:More citations needed Template:Automatic taxobox
Circaetinae is a subfamily of the family Accipitridae which contains a group of medium to large broad-winged birds of prey.<ref>Template:Cite journal</ref><ref>Template:Cite book</ref> The group is sometimes treated as tribe Circaetini.<ref>Template:Cite book</ref><ref>Template:Cite web</ref> These birds mainly specialise in feeding on snakes and other reptiles, which is the reason most are referred to as "snake-eagles" or "serpent-eagles". The exceptions are the bateleur, a more generalised hunter, and the Philippine eagle, which preys on mammals and birds.
All but one of the subfamily are restricted to warmer parts of the Old World: Spilornis and Pithecophaga in south Asia, the others in Africa. The short-toed eagle Circaetus gallicus migrates between temperate Eurasia and Africa, as well as being resident in India.
They have hooked beaks for tearing flesh from their prey, strong legs and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance.
Taxonomy
The subfamily Circaetinae was introduced in 1851 by the English zoologist Edward Blyth with Circaetus as the type genus.<ref>Template:Cite journal</ref><ref>Template:Cite book</ref>
The genus level cladogram of the Circaetinae shown below is based on a molecular phylogenetic study of the Accipitridae by Therese Catanach and collaborators that was published in 2024.<ref>Template:Cite journal</ref> Template:Clade
The following taxonomy is based on the International Ornithological Congress.<ref name=ioc>Template:Cite web</ref>
