The Alejandro Selkirk firecrown (Sephanoides fernandensis leyboldi) is an extinct subspecies of the Juan Fernández firecrown that lived on Alejandro Selkirk Island in the Juan Fernández Archipelago belonging to Chile.[1]
Taxonomy

Most worldwide taxonomic systems accept this species as putative. However, a few authors question this subspecies and whether a firecrown ever existed on Alejandro Selkirk Island.[2]
Extinction
The Alejandro Selkirk firecrown may have went extinct due to deforestation, erosion and predation by introduced cats, rats, goats, and rabbits.[3] It might have also competed with the introduction of plants such as Luma apiculata, as well as the green-backed firecrown. It was last seen in 1908, but the sighting was unconfirmed.[3]
