Antarctic Giant Petrel

Popular penguin films fail to disclose a terrible and dark shadow looming over the colonies of these almost humanlike Antarctic waterbirds. Macronectes giganteus. The Southern Giant Petrel. Weighing up to 18 pounds (8 kg) with a wingspan of 7 feet (2 meters,) the ghastly Giant Petrel stalks the colonies of multiple penguin species. Entire adult penguins and the large young of huge Emperor Penguins are seized by this monstrous, yellow eyed marine bird with the appearance of a gigantic gull or demonized albatross. Having no raptorial adaptations, this terrifying avian freak of nature conducts incredibly crude and brutal butcherings in its bid to live like an eagle. You can see a shocking attack here.
