Guadalupe caracara

The Guadalupe caracara was similar to the crested caracara, but differed in having less white on the upper breast and being barred on the belly rather than black. ==Distribution and taxonomy==

This species inhabited Mexico's Guadalupe Island until the beginning of the 20th century. The crested caracara is sometimes incorrectly referred to as "Guadalupe caracara", because the extinct birds were formerly considered a subspecies of the extant taxon. They were reinstated as a full species in 2000. ==History==

Described as "evil" and "vicious" by early observers, it was driven to extinction by a hunting and poisoning campaign led by goat herders on Guadalupe Island. As described by Edward Palmer: ==Conservation==

In 1876 the species was common throughout the island. 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. In an apparent case of coextinction, the ischnoceran louse Acutifrons caracarensis is only known from the Guadalupe caracara. Around 35 specimens (skins, skeletons and two eggs) remain in public collections today. Specimens are available for display in Chicago, Washington, and London. ==References==
