It is an endemic species to Revillagigedo Islands Mexico, and is considered endangered. Global population has been estimated on 46,000 individuals with a downward trend. Previously nests in Clarion and San Benedicto, now only found in Socorro. In 1952, the Barcena Volcano eruption destroyed the population of Saint Benedict, later some individuals have been recorded, but has not been confirmed to be reproduced again. Previously two subspecies were recognized P. a. auricularis and P. a. newelli, in 2004 the two were separated and raised to species level.
