I always wondered how they ate the fish, with such long slender beaks, and its fascinating to watch, how they grip the fish, turning it around and then...plop...into its wide maw, or "crop" that is our word for today.
A crop is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods, earthworms, leeches, and insects.
