Assessment Summary

Assessment Summary – November 2004

Common name:
Ancient Murrelet

Scientific name:
Synthliboramphus Antiquus

Status:
Special Concern

Reason for designation:
This burrow-nesting seabird is impacted by mammalian predators that have been introduced to its breeding islands. Predators have been removed from some islands but populations have not increased as a result. About half of the world population nests in the Queen Charlotte Islands, British Columbia; the Canadian population is thought to be declining.

Occurrence:
British Columbia

Status history:
Designated Special Concern in April 1993. Status re-examined and confirmed in November 2004. Last assessment based on an update status report.
