Great skuas look like bulky brown gulls. They have a large hooked bill. Make sure you are wearing gloves if you want to help a wounded great skua lying on the beach! Great skuas spend practically the entire year at sea, hunting fish and fish waste. They act like true pirates around fishing vessels, where they get their food here by pestering gulls and terns until they let go of their prey or disgorge it out of fear. Great skuas don't even hesitate to kill their victim as well.
