Northern Giant-petrel (Macronectes halli)

Order: Procellariiformes
Family: Procellariidae

The Northern Giant-petrel is a large, robust seabird found in the Southern Ocean, including the coasts of Patagonia. With a wingspan reaching up to 2 meters, it is one of the largest petrels. Adults are mostly dark brown with a massive, pale bill tipped with a reddish tip. Unlike its close relative, the Southern Giant-petrel, this species has a more uniform plumage and lacks the greenish bill tip. Northern Giant-petrels are highly adaptable, feeding on a wide range of food from live prey to carrion. They are often seen following fishing vessels or scavenging at seal and penguin colonies. Their strong sense of smell helps them locate food over vast distances at sea. Breeding occurs on remote islands, where they nest on open ground, often in loose colonies. The species is considered Near Threatened due to threats from fisheries bycatch and changes in food availability.

Habitat

Open ocean, coastal waters, and subantarctic islands, especially near breeding colonies and rich feeding grounds.

Foraging

Feeds by scavenging carrion, hunting live prey, and following ships for discards.
