 Increased tourist developments and birds getting caught in nets from commercial fishing operations also pose a danger.It is also threatened by introduced species such as mice, rats and feral cats; this threat has been lessened lately by efforts to restore its habitat by removing introduced predators.This species was described, named and dedicated to Federico Craveri and Ettore Craveri by the ornithologist Tommaso Salvadori, in acknowledgment of the fact that the Craveri brothers had enriched the Turin Museum of Natural History with many species of birds of Mexico and California.
