About 19, see article The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species.

They also have extremely keen eyesight to enable them to spot potential prey from a distance.

At one time, several types were grouped, including large assemblages such as booted eagles, but modern studies using mitochondrial DNA clarified that this subfamily was smaller than formerly classified.

[6] Unlike the many lineages of Accipitridae which seem to have radiated out of Africa or South Asia, the Buteoninae clearly originated in the Americas based on fossil records and current species distributions (more than 75% of the extant raptors from this lineage are found in the Americas).

It is based on a molecular phylogenetic study of the family Accipitridae by Therese Catanach and collaborators that was published in 2024.
