捕食: Craveri's Murrelet Synthliboramphus craveri) is listed as 'Vulnerable (VU)' in the IUCN Red List of Threatened Species. It has a small breeding range, It breeds on Islas Partida, Tiburón, San Jorge, San Esteban, Estanque, San Pedro Mártir, San Pedro Nolasco, San Francisco, Espíritu Santo and San Ildefonso, and possibly on the Pacific coast of Baja California, north to Islas San Benitos. Introduced predators mainly cats (Felis catus), black rats (Rattus rattus) and Deer mice (Peromyscus maniculatus) to some extent predate on adults and chicks, and have caused declines in population numbers. Craveri's Murrelet was most probably extirpated from the San Jorge's islands due to predation by introduced mammals (BirdLife International 2010)
