Justification of Red List category
In 1980, this robin had the smallest population of any bird species for which precise figures were known and it seemed doomed to extinction. Its spectacular recovery, following intensive management, is a renowned conservation success worldwide. Although numbers continue to increase, it still has a very small population and is therefore classified as Endangered.
