Distribution

Region

Baja California Pacific islands

Typical Environment

Formerly restricted to Guadalupe Island, where it used open scrub, rocky slopes, and coastal areas. It often patrolled around seabird colonies and shoreline wrack lines for carrion. The species exploited carcasses of introduced goats and dead seabirds, and also hunted small vertebrates and invertebrates. Widespread habitat degradation by feral goats likely reduced nesting sites and prey availability before its extinction.

Useful to know

Also called the mourning caracara, it was endemic to Guadalupe Island off Baja California, Mexico, and is one of the few raptors known to have gone extinct in historic times. Its bold, inquisitive nature made it unusually approachable, which, combined with persecution and habitat degradation by introduced goats, hastened its demise. It was once placed in Polyborus and long treated as close to, or within, the crested caracara complex.
