They will run into penguin burrows to eat chicks or penguin eggs and are considered a pest during the Rockhopper penguin breeding season.
Despite being a member of the falcon family, they do not behave like most falcons! They spend a lot of time on the ground and have very powerful legs which they use to turn over pieces of driftwood and rocks to find crustaceans.
They will scavenge from people and have been known to raid rubbish bins and even run into tents to take food items. During the Falklands War, they would wait outside the soldiers tents in order to swoop down and steal their rations.
