    Details of this species in Mexico
    Status: Alien
    Invasiveness: Invasive
    Occurrence: Present/controlled

    Species Notes for this Location:
    Feral cats were present on 26 islands in north-west Mexico in 1994. They have since been eradicated from 15 of these.
    Management Notes for this Location:
    Feral cats were eradicated using a combination of hunting, dogs and trapping. Hunting at night with .22 and .222 calibre rifles was found to be most effective. Hunting during the day was most effective using trained dogs, particularly Jack Russell Terriers. Victor #1½ padded leg-hold traps were used, and were particularly effective in removing the last few cats. Cubby sets (where the trap blocks the single entrance to a cave or hole with bait/scent behind the trap) and walk-through sets (where the trap is along a trail with bait/scent placed above or to the side of the trap) were used. The location of tracks and scats were used to guide placement of the traps.
    Location Notes:
    Predation: 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)
    Reduction in native biodiversity: It is reported that in northwestern Mexico, on the islands of Baja, California, cats have caused rodent extinctions with over 10 taxa extinct or nearly extinct (Nogales et al 2004).
