					Total Length:  15 to 19 cm; Wingspan:  38 to 42 cm (Ref. 8812).  Population is affected by some predation, krill exploitation, and breeding success due to snow blocking burrows (Ref. 84934). Inhabits open ocean (Ref. 81748); found over seas and along shores (Ref. 83946).  Exhibits dipping and pattering (Ref. 81748).   Skips and hops over water surface while feeding.  A colonial breeder.  Typically gregarious at sea.  Often trail ships (Ref. 91362).
