Guadalupe Caracara (Caracara lutosa)


Taxonomy

French: Caracara de Guadalupe German: Guadalupekarakara Spanish: Carancho de Guadalupe
Taxonomy:

Polyborus Lutosus

Ridgway

, 1876,

Guadalupe Island

.

Previously placed in genus Polyborus, now shown to be invalid as type unidentifiable#R#R. Frequently treated as a race of C. cheriway, and, together with latter, often regarded as race of C. plancus. Initial DNA studies, however, suggested that present form was a distinct species#R, and this view was supported by later molecular analysis#R. Monotypic.

Distribution:

Guadalupe I, off W Baja California, NW Mexico.

Last recorded in 1903#R#R. Decline and ultimate extinction due primarily to direct persecution by settlers, who often shot large numbers of this species which had gathered at water-holes#R. Loss of vegetation cover through overgrazing by introduced goats may also have played a part.
