Population justification: None remain. Buller described them as common in the 1870s, but there were few specimens ever collected (specimens are only known to exist in Chicago, Tring, Philadelphia and Wellington), the last being from 1902. Occasional sight records persisted until 1970 (Tennyson and Martinson 2006).
