Southern Giant Petrel Macronectes giganteus
Part-scavenger and part-predator, this large petrel is often seen on the fringes of penguin colonies or near the carcasses of dead seals and whales. It uses its powerful bill to tear apart carrion and to kill young birds. Most adults have a pale head and a dark grayish brown back, but some are almost completely white with scattered black flecks.
