The Buteoninae are a subfamily of

birds of prey Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively predation, hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds). In addition to speed ...

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

Systematics

The subfamily Buteoninae was introduced (as "Buteonina") by the Irish zoologist Nicholas Vigors in 1825 with '' Buteo'' as the

type genus In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearin ...

. 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).
