Circaetus, the snake eagles, is a genus of medium-sized eagles in the bird of prey family Accipitridae. The genus name is from the Ancient Greek kirkos, a type of hawk, and aetos, "eagle". These are mainly resident African species, but the migratory short-toed snake eagle breeds from the Mediterranean basin into Russia, the Middle East and India, and winters in sub-Saharan Africa and east to Indonesia. Snake eagles are found in open habitats like cultivated plains arid savanna, but require trees in which to build a stick nest. The single egg is incubated mainly or entirely by the female.
