Crested caracara (C. plancus) in flight

Caracaras are birds of prey in the family Falconidae. They are traditionally placed in subfamily Polyborinae with the forest falcons,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> but are sometimes considered to constitute their own subfamily, Caracarinae,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> or classified as members of the true falcon subfamily, Falconinae.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Caracaras are principally birds of South and Central America, just reaching the southern United States.

Unlike the Falco falcons in the same family, the birds in the five relevant genera are not fast-flying aerial hunters, but are comparatively slow and are often scavengers (a notable exception being the red-throated caracara).

Distribution

The caracaras are found throughout much of the Americas. The range of the crested caracara extends as far north as the states of Arizona, Texas, and Florida in the United States.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In the Southern Hemisphere, the striated caracara inhabits the Falkland Islands and Tierra del Fuego, just off the coast of the southernmost tip of South America.<ref>Template:Cite journal</ref>

Taxonomy

The genus Caracara Merrem 1826 was previously known as Polyborus Vieillot 1816. Hence, the differing subfamily names Polyborinae or Caracarinae. In addition, different authors give differing scopes to the subfamily, sometimes including the forest falcons, laughing falcon, or spot-winged falconet.

Peters' checklist<ref>Template:Cite book</ref> in 1931 listed the caracaras in their own subfamily, Polyborinae, containing Daptrius, Milvago, Phalcobœnus, and Polyborus. Ibycter americanus is included as Daptrius americanus.

Whilst recognizing "three major, deep divisions in the Falconidae",<ref name=SACCBaseline05>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> the South American Classification Committee (SACC) of the American Ornithologists' Union voted<ref name=SACCprop281>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> in 2007 to recognize two subfamilies: Herpetotherinae containing the forest falcons; and Falconinae containing the caracaras and true falcons.

Based on recent research in molecular genetics,<ref name=Fuchs2012>Template:Cite journal</ref> John Boyd<ref name=TiF-Falc>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> places the spot-winged falconet (Spiziapteryx) in Caracarinae, and the forest falcons in Herpetotherinae. He also comments that "many of the caracaras are closely related, and it would not be unreasonable to merge Ibycter, Milvago, and Phalcoboenus into Daptrius".
