Family Stercorariidae is a group of predatory seabirds commonly referred to as the skuas. These birds are known for their aggressive behavior and are often seen stealing food from other birds. The term "skuas" is often used synonymously with the scientific name Stercorariidae, and refers to the family's predatory nature. Other synonyms for this family include the jaegers, which are smaller species of skuas, and the parasitic jaegers, which are known for their habit of chasing smaller birds to steal their food. Despite their reputation as aggressive predators, skuas are an important part of many marine ecosystems and play a vital role in maintaining the balance of these delicate environments.
