Very little known; presumably fairly sedentary, remaining throughout year in waters adjacent to the colony, but movements at sea difficult to detect. Some dispersal northwards, e.g. from Falklands to N Argentina; may be more pelagic in dispersal than other species, and possibly even migratory to some extent.   (del Hoyo J, Elliott A, Sargatal J (eds), 1992)
