Skuas are seabirds in the family Stercorariidae. The three smaller skuas are called jaegers in North America.
They are in general medium to large birds, typically with grey or brown plumage, often with white markings on the wings. They have longish bills with a hooked tip, and webbed feet with sharp claws. They look like large dark gulls, but have a fleshy cere above the upper mandible. They are strong, acrobatic fliers.
