Skuas are seabirds that are commonly found in the sub-Antarctic and polar regions. These birds are known for their aggressive behavior and are often seen scavenging for food. There are several synonyms for the word skuas, including jaegers, gulls, and predatory birds. Jaegers are a type of seabird that belong to the same family as skuas, and are known for their hunting abilities. Gulls are also similar in appearance to skuas, but are less aggressive and are found in more coastal areas. Predatory birds is a broader term that encompasses all birds that hunt and kill other animals for food.
