Greylag geese are the wild ancestors of domestic geese. They are extremely familiar birds. During their migratory journey, families travel together, parents with their offspring. Family groups keep together in the wintering areas and maintain a certain separation from other families. They have a very elaborate social behaviour and have been protagonists of literary works such as "The Wonderful Adventures of Nils Holgersson", a story book by the Swedish author Selma Lagerlöf that is worth reading. These geese were the birds that allowed the Austrian Nobel Prize, Professor Konrad Lorenz, the discovery of the physiological and ethological process of imprinting, a mechanism that establishes mother-baby relationships in most animal species.
