The Guadalupe Caracara, Caracara lutosa or lotusos, is an extinct bird of prey belonging to the falcon family (Falconidae).

This species inhabited Mexico's Guadalupe Island until the beginning of the 20th century. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America. Guadalupe Island, or Isla Guadalupe ( is a volcanic island located 241 kilometers (150 Statute miles off the west coast of Mexico 's Baja The twentieth century of the Common Era began on The Crested Caracara is sometimes incorrectly referred to as "Guadalupe Caracara", because the extinct birds were formerly considered a subspecies of the extant taxon. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. A taxon (plural taxa) or taxonomic unit, is a name designating an organism or a group of Organisms In Biological nomenclature according to They were reinstated as a full species in 2000. ^[2]

It was described as "evil" and "vicious" by early observers. It was driven to extinction by a hunting and poisoning campaign led by goatherders on Guadalupe Island. In 1876 the species was common throughout the island. ^[1] However, in March 1897, only one bird was encountered,^[3] but additional members of the species survived. Year 1897 ( MDCCCXCVII) was a Common year starting on Friday (link will display the full calendar of the Gregorian Calendar (or a Common On December 1, 1900 collector Rollo Beck encountered 11 and preserved nine as scientific specimens.

The Guadalupe Caracara is one of the few species that were intentionally rendered extinct by humans. In its particular case, it was demanded by goat farmers that the birds were to be killed off as they occasionally fed on young goats (though the role of the caracara as a predator of goats was much exaggerated). ^[1] It stands to note that its erstwhile home was at that time being devastated by tens of thousands of goats gone feral, leading to the extinction of several endemic species caused by the near-total destruction of habitat. ^[6]

In an apparent case of coextinction, the ischnoceran louse Acutifrons caracarensis is only known from the Guadalupe Caracara. Coextinction of a Species is the loss of one species upon the Extinction of another The Ischnocera is a large suborder of lice mostly parasitic on Birds but including a large family (the Trichodectidae) parasitic on Lice (singular louse) ( order Phthiraptera) are an order of over 3000 Species of wingless Insects three of which are classified ^[7]
