Order: Procellariiformes
Family: Procellariidae
The Southern Giant-petrel is a powerful and imposing seabird found throughout the southern oceans, including the coasts of Patagonia. Adults are large, with a heavy bill and a wingspan that can exceed 2 meters. Their plumage varies from mottled brown to almost white, and they are easily recognized by their robust build and prominent nostrils. These birds are highly opportunistic, feeding on carrion, fish, squid, and even preying on other seabirds. They are often seen following ships or gathering in large numbers around whale carcasses. Southern Giant-petrels breed on remote islands, nesting on open ground and fiercely defending their territories. Their adaptability and aggressive nature make them a dominant presence in their ecosystem, playing a crucial role in cleaning up dead animals and maintaining ecological balance.
Habitat
Coastal waters, open ocean, and subantarctic islands, especially near breeding colonies and rich feeding grounds.
Foraging
