Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. First described by English illustrator John Frederick Miller in 1779, the Secretary Bird was soon moved to its own genus, Sagittarius, by French naturalist Johann Hermann in his Tabula Affinatum Animalium.It was not until 1935 that the species was moved to its own family, distinct from all other birds of prey a classification confirmed by molecular systematics.Recent cladistic analysis has shown Sagittariidae to be an older branch of the diurnal birds of prey than Accipitridae and Falconidae, but a younger divergence than Cathartidae. Sometimes, the enigmatic bird Eremopezus is classified as an early relative of the secretary bird, though this is quite uncertain as the bird is only known from a few fragmentary body parts such as the legs. The earliest fossils associated with the family are two species from the genus Pelargopappus. The two species, from the Oligocene and Miocene respectively, where not discovered in Africa but France.
