					Total Length:  79 to 89 cm (Ref. 8812).  Breeds biennially  from September to October in Southern Ocean islands.  World population is estimated at 150,000 birds, or some 25,000 breeding pairs.  Current threat is long-line fishing that kills about 4,000 birds per year (Ref. 84934). Scavenging; surface seizing; oceanic (Ref. 356).
