With a similar behavior between a hawk and a vulture, brown Mugger eats other sea birds, their young and eggs, while not depreciated to dead animals and waste from ships. It also uses the well-known system of gulls launched from the air in some bivalve repeatedly breaking its shell. Bird apparently has a fondness for pigeons, petrels, which draws from their burrows, but if the bird does safarse, can hardly be achieved due to its erratic flight.
Nesting in the Antarctic archipelago west to latitude 65 º S., and Shetland islands and southern South Orkneys, South Georgia, and possibly in the South Sandwich chain.
