After a pelican caught fish, a brown noddy was landing on his head and tried to get a piece of the pelican's catch. With each catch, a pelican picks up many litres [over a gallon] of water into his flexible pouch. It releases this water by slightly opening its bill, while pointing the bill downward. Only thereafter, a pelican can swallow the remaining fish. During this procedure, the brown noddy is waiting for the pelican to open its bill, hoping to prey on some pieces while the pelican is tossing and swallowing its catch.Source
