Buteoninae

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

They have large, powerful, 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.

This subfamily contains the buzzards (buteonine hawks) with great diversity in appearance and form and some appearing eagle-like, with at least 50 species included overall in the subfamily. 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.

Systematics
The subfamily Buteoninae was introduced (as "Buteonina") by the Irish zoologist Nicholas Vigors in 1825 with Buteo as the type genus. The subfamily includes about 79 currently recognized species. 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).

A genus level cladogram of the Buteoninae is shown below. It is based on a molecular phylogenetic study of the family Accipitridae by Therese Catanach and collaborators that was published in 2024.
