Justification of Red List category
This species had shown a significant increase during the past two decades (probably owing to greater availability of carrion from expanding populations of fur seals, increased waste from commercial fishing operations, and the use of measures to reduce seabird bycatch around some breeding colonies). It no longer approaches the threshold for classification as threatened and is therefore classified as Least Concern.
