The Great Skua, also known as the bonxie, is a large seabird found in the northern hemisphere. Synonyms for this bird include the Northern Skua, Arctic Skua, and Brown Skua. The Great Skua is known for its aggressive behavior, stealing food from other seabirds and even attacking them to force them to regurgitate their meals. The name bonxie is believed to come from the Old Norse word for "bent beak," which describes the strong, hooked bill of the bird. Despite their aggressive behavior, the Great Skua plays an important role in the ecosystem as a predator and scavenger.
