The southern giant petrel is an extremely aggressive predator which has a range of food sources from carrion, krill and squid, to other sea birds. They have some interesting nick-names, such as ‘stinker’ and stinkpot’. Given the opportunity, they will kill penguin chicks and have been known to prey on other pelagic seabirds such as the smaller albatrosses. In these images, a group of birds are feeding from a dead penguin in Antarctic waters, two are engaged in a fierce battle watched by a white morph giant petrel known asa white nelly, and another is leaving a penguin colony after an unsuccessful forage. The horny part seen clearly above the bird’s bill is the salt gland used for removing salt from the blood of the bird following its ingestion of salt water.
