    Impacts:
    Reduction in native biodiversity: House mouse, Mus musculus are highly omnivorous, and are known to eat seeds, flowers and invertebrates, including giant ground beetles (Ashmole and Ashmole, 2000 in Varnham, 2006). They may predate on the 'Critically Endangered (CR)' endemic wirebird's (see Charadrius sanctaehelenae in IUCN Red List of Threatened Species) eggs (known to eat eggs of ground nesting birds elsewhere in the world) (McCulloch and Norris, undated in Varnham, 2006).
    Threat to endangered species: House mouse, Mus musculus are implicated in the decline of endemic snails (Succinea spp.) , the 'Critically Endangered (CR)' giant earwig (see Labidura herculeana in IUCN Red List of Threatened Species) and other endemic invertebrates on the island (McCulloch and Norris, undated in Varnham, 2006).
