Justification of Red List category
Past intensive sheep-grazing and ongoing persistent locust swarms have dramatically reduced and degraded the available habitat for this species. Combined with cat predation, which effectively removes mockingbirds from areas with little or no understorey, declines in its extremely small range are considered likely. Sheep eradication appears to have led to the population trend stabilising, but despite this and ongoing cat eradication, the species has not yet expanded its range. Therefore, it is listed as Critically Endangered.
