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.

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.

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:

The "Calalie" is abundant on every part of the island; and no bird could be a more persistent or more cruel enemy of the poultry and domestic animals. It is continually on the watch, and in spite of every precaution often snatches its prey from the very doors of the houses. The destruction of the wild goats is not so great, as these animals are better able to protect themselves than the tame ones. No sooner is one kid born - while the mother is in labor with the second - than the birds pounce upon it; and should the old one be able to interfere, she is also assaulted. No kid is safe from their attacks. Should a number be together, the birds unite their forces, and, with great noise and flapping of their wings, generally manage to separate the weakest one and dispatch it. They sometimes fasten upon the tongue when the poor creature opens its mouth to bleat, and have been known to tear it out, leaving the animal to perish, if not otherwise destroyed. Sometimes the anus is the point of first attack. The birds are cruel in the extreme, and the torture sometimes inflicted upon the defenceless animals is painful to witness... …
