Gull-like birds are a type of seabird that are characterized by their webbed feet and long wings. Two examples of these birds are terns and skuas. Terns are medium-sized birds with long, pointed wings and a forked tail. They are often seen in large flocks near the shoreline. Skuas are larger than terns and have a more powerful flight. They are known to be aggressive predators and will often chase other birds away from their nests.
