The Guadalupe Caracara is an extinct member of the Crested Caracara superspecies. It formerly was very common on the island of Guadalupe in the Pacific Ocean west of Baja California. Toward the end of the 19th century, however, this caracara began to be perceived as a threat to the livelihood of the island’s goat herders. Within the matter of a decade the Guadalupe Caracara was eliminated from the island by persistent human persecution. Due to their incredibly bold and fearless nature the Guadalupe Caracara easily was shot with rifles or poisoned at watering holes. This was probably one of those rare instances when humans have intentionally caused the extinction of a species of bird, for no other reason than to have it removed from the ecosystem.
