    Predation: The Pink-footed Shearwater (Puffinus creatopus) is lested as 'Vulnerable (VU)' in the IUCN Red List of Threatened Species. It breeds only on Robinson Crusoe and Santa Clara of the Juan Fernandez group; Isla Mocha and Isla Guafo (recent evidence). Major threats to this species include habitat degradation due to herbivory and trampling, and predation by introduced mammals. Invasive species threats on Robinson Crusoe include predation by cats (Felis catus), rats (Rattus spp.) and coaties (Nasua nasua) and habitat degradation due to herbivory and trampling of rabbits (Oryctolagus cuniculus), cattle (Bos taurus) and goats (Capra hircus) causing erosion and burrow loss. On Isla Mocha predation by rats maybe an issue. Rabbits have been eradicated on Santa Clara. Other threats include ententanglement in fishing gear and impact of longline fishing activities (BirdLife International 2012c)
    Predation: Defilippe's Petrel (Pterodroma defilippiana) is listed as 'Vulnerable (VU)' in the IUCN Red List of Threatened Species. It has a small breeding range at three or four locations on islands off the coast of Chile- In the Des Venturadas Islands- San Ambrosio and San Felix and in the Juan Fernandez Islands - on Santa Clara. It is believed to be extirpated on Robinson Crusoe Is. due to predation by feral cats (Felis catus) and coaties (Nasua nasua); on San Felix predation by cats are believed to have caused extensive mortality (BitdLife International 2012d)
