This species is listed as Near Threatened because it is suspected to have a moderately small range. If this was found to be in decline or smaller than suspected, the species may qualify for uplisting to a higher threat category. It frequents open sea all-year-round, only approaching land during the breeding season, at dusk and after dark. Its foraging areas are poorly known, but presumably related to highly productive areas of oceanic upwelling. It flies low, taking food from the surface of sea, probably mainly plankton e.g. fish eggs, ctenophores and polychaete worms).
