Duck or anitra, from the Latin anas is the common name of an important number of anseriform birds, generally migratory, belongin

Duck or anitra, from the Latin anas is the common name of an important number of anseriform birds, generally migratory, belonging to the Anatidae family. It is a definition devoid of systematic value, as it groups species belonging to various different genera and sub-families; in general the term `duck` applies to the smaller Anseriform species and with marked sexual dimorphism, as opposed to goose, which on the contrary defines species of great size and devoid of dimorphism.
