Is the Guadalupe flicker extinct

The Guadalupe flicker, a bird species native to the islands off the coast of Mexico, is considered extinct. The last confirmed sighting was in the 1980s, and extensive searches have failed to locate any individuals since then. Habitat destruction and predation by introduced species are believed to have contributed to its decline. Conservation efforts have focused on protecting its former habitat, but as of now, the species is not known to exist.
