Caracara is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara, and one recently extinct species, the Guadalupe caracara. The crested caracara had in recent years been split into a northern species C. cheriway and a southern species C. plancus, but the South American Classification Committee of the American Ornithological Society has voted to again merge the two, retaining C. plancus as the crested caracara.{{Cite web|url=https://www.museum.lsu.edu/~Remsen/SACCBaseline.htm|title=South American Classification Committee|website=Museum.lsu.edu|access-date=17 March 2022}} The taxonomists of the International Ornithologists' Union have also merged them.{{cite web |url=https://www.worldbirdnames.org/new/updates/proposed-splits/ |title=IOC World Bird List (v 10.2) Proposed Splits/Lumps |last1=Gill |first1= F. |last2=Donsker|first2=D.|last3=Rasmussen |first3=P.|website=Worldbirdnames.org|date=December 2020 |access-date=2 January 2021 }}

Appearance

The crested caracara is distinguished by its long legs and medium size.{{Cite web|url=https://www.britannica.com/animal/caracara|title=Caracara {{!}} bird|website=Encyclopædia Britannica|language=en|access-date=2019-12-04}} The birds can reach a length of {{cvt|49|-|58|cm}} from head to tail.{{Cite web|url=https://www.allaboutbirds.org/guide/Crested_Caracara/id|title=Crested Caracara Identification, All About Birds, Cornell Lab of Ornithology |website=Allaboutbirds.org|language=en|access-date=2019-12-04}} There are usually four points of identification of the caracara: strikingly white markings on the neck, the tip of both wings, and the tail.{{Cite web|url=https://houstonaudubon.org/birding/gallery/crested-caracara.html|title=Crested Caracara {{!}} Bird Gallery {{!}} Houston Audubon|website=Houstonaudubon.org|language=en|access-date=2019-12-04}} Along with their medium length, the caracara also has a wingspan of {{cvt|122|-|129|cm}}. When flying, the caracara is often noted to have a pattern on their underside that looks like a cross.{{Cite web|url=https://wildlatitudes.com/crested-caracara-1/|title=Crested Caracara: Not Your Everyday Falcon|website=Wildlatitudes.com|language=en-US|access-date=2019-12-04}}

Behavior

The behaviors of caracaras are considered quite strange in relation to those of other falcons.{{Cite web|url=https://houstonaudubon.org/birding/gallery/crested-caracara.html|title=Crested Caracara {{!}} Bird Gallery {{!}} Houston Audubon|website=Houstonaudubon.org|language=en|access-date=4 December 2019}} The bird is often seen walking on the ground in search of prey.{{Cite web|url=https://birdsna.org/Species-Account/bna/species/crecar1/introduction|title=Crested Caracara - Introduction|work=Birds of North America Online|access-date=4 December 2019|archive-date=23 October 2019|archive-url=https://web.archive.org/web/20191023145924/https://birdsna.org/Species-Account/bna/species/crecar1/introduction|url-status=dead}} In addition to a preference of walking over flying, the birds also create close bonds with their mates. Caracaras are territorial creatures who are year-round landlords of trees and land that they occupy. Their aggression is an extension of this, which is why they have been seen taking food from much larger creatures like vultures.{{Cite web |url=http://www.birdsoftheworld.org/bow/species/crecar1/cur/introduction |title=Crested Caracara Caracara cheriway |work=Birds of the World |publisher=Cornell Lab of Ornithology |access-date=17 March 2022 |archive-date=19 June 2021 |archive-url=https://web.archive.org/web/20210619155531/https://birdsoftheworld.org/bow/species/crecar1/cur/introduction |url-status=dead }}{{Cite web |url=https://www.fws.gov/verobeach/MSRPPDFs/AudubonsCrestedCaracara.pdf |title=Audubon's Crested Caracara Polyborus plancus audubonii |publisher=U.S. Fish and Wildlife Service|access-date=4 December 2019 |archive-date=4 December 2019 |archive-url=https://web.archive.org/web/20191204075913/https://www.fws.gov/verobeach/MSRPPDFs/AudubonsCrestedCaracara.pdf |url-status=dead }} In flight, this bird is known for having very direct flight.

Taxonomy and fossil record

File:Schopfkarakara.jpg]]

The crested caracara is the only extant species in Caracara, and was formerly separated into two species, the northern and southern crested caracaras. The modern range includes Cuba, South America, most of Central America and Mexico, just reaching the southernmost parts of the United States, including Florida and Southeast Texas.{{ITIS |id=175594|taxon=Caracara |access-date=3 April 2011}}

Native to Guadalupe Island off the west coast of Baja California, the Guadalupe caracara was hunted to extinction by 1906.

An additional six species have been described on the basis of fossil and subfossil records:
