    Impacts:
    Threat to endangered species: Feral cats were introduced to Socorro in the early 1970's and have been implicated in reducing the critically endangered Townsend's shearwater (Puffinus auricularis in IUCN Redlist of Threatened Species) numbers. More than 92% of cat scats above 500m have been reported to contain shearwater remains. P. auricularis has been extirpated from two islands (Clarion and San Benedicto), and breeding is now restricted to an extremely small area on one island. Sheep (Ovis aries) are also a threat to nesting habitats through grazing (BirdLife International 2006).
